5 Common Reasons for Divorce in Canada: History, Statistics, Causes, and the Legal Process in 2026
Divorce has undergone a remarkable transformation over the past century. What was once an exclusive privilege of the wealthy has become a legal right available to all Canadians, regardless of gender or financial status.
The journey from private Acts of Parliament to no-fault divorce reflects broader changes in Canadian society, gender equality, and the legal system itself.
This guide traces that history, examines the current state of divorce in Canada with the latest 2026 statistics, explores the most common reasons marriages end, and explains what the divorce process looks like today.
A Brief History of Divorce Law in Canada
Before 1968, getting a divorce in Canada was extraordinarily difficult. The grounds for divorce were extremely narrow. A husband could divorce his wife if he could prove adultery, but a wife generally had to prove adultery combined with cruelty, desertion, or other aggravating conduct.
Some provinces had no divorce courts at all, forcing couples to seek a private Act of Parliament, a process that persisted in Quebec and Newfoundland until the 1968 reforms.
Only the wealthiest Canadians could afford this route, leaving most unhappy couples with no legal way to end their marriages.
The Divorce Act of 1968 changed everything.
For the first time, Parliament established a uniform divorce law across Canada. The 1968 Act widened the reasons for divorce from adultery alone to include mental or physical cruelty, desertion, separation for three years, or having an imprisoned spouse. It also introduced no-fault grounds alongside fault-based grounds.
The divorce rate surged immediately after 1968, likely because many couples who had previously lacked a viable legal route now had access to one.
The next major reform came in 1985, with the revised Divorce Act taking effect on June 1, 1986. This revised act fully embraced no-fault divorce, making marriage breakdown the sole ground for divorce. Marriage breakdown could be established in three ways: living apart for at least one year, committing adultery, or treating the other spouse with physical or mental cruelty.
The separation period was reduced from three years to one. Courts generally prefer the no-fault one-year separation ground because adultery and cruelty carry social stigma and tend to increase conflict.
In 1923, women gained the right to petition for divorce on the same grounds as men, a significant milestone in gender equality under the law. Before this change, women faced far higher barriers to ending a marriage than men did.
Divorce Statistics in Canada: What the Numbers Say in 2026
Understanding the current divorce landscape requires looking at several different measures, each telling a slightly different story.
The lifetime divorce rate. Approximately 38 to 40% of marriages in Canada end in divorce. This means roughly two in five couples will eventually separate legally. The divorce rate has remained relatively stable over the past 15 years after peaking in the 1980s and 1990s.
Statistics Canada's total divorce rate, an actuarial measure that estimates lifetime divorce probability based on current age-specific rates, stood at 369.4 per 1,000 marriages in 2019, which translates to roughly 37%.
With divorce rates continuing to decline and the married population becoming increasingly self-selected (older, more financially stable, more deliberate), the real number today is likely below 40% and falling.
The annual divorce rate. The most recent official data from Statistics Canada is from 2020, when Canada's divorce rate stood at 5.6 per 1,000 married persons, a 50-year low.
No official figures have been published for 2021 through 2025, and no other government source provides post-2020 divorce counts. Many websites cite "current" or "2025" divorce rates for Canada, but that data does not exist.
In 2020, 42,933 divorces were granted across the country. This represents a significant drop from more than 62,000 divorces in 2016. The 2020 figure was partly depressed by pandemic court closures and delays in processing cases.
Family law cases in 2024-2025. According to Statistics Canada's Civil Court Survey released on March 26, 2026, there were just over 278,500 family law cases active at some point in 2024-2025 in the six provinces and three territories that reported data.
Of those cases, 108,273, or 39%, were newly initiated, and 170,230, or 61%, were ongoing from a previous fiscal year.
Nearly half, 45%, of the active family law caseload pertained to divorce applications. Divorce cases without issues accounted for 28% of family law cases, though issues regarding finances, children, and property may have been dealt with earlier in a separation agreement.
Regional variations. Divorce rates differ noticeably between Canadian provinces. Quebec has unique patterns with more common-law partnerships. Alberta and British Columbia show slightly higher divorce rates. The Atlantic provinces tend toward lower separation rates. Ontario sits near the national average.
Age and marriage duration. Most divorces happen between 5 and 15 years of marriage. The average marriage length before separation is approximately 13 to 14 years. Early divorce within the first 5 years accounts for about 25% of all separations.
The so-called "seven-year itch" represents a real phenomenon in the statistics. Marriages before age 20 have significantly higher failure rates, while the mid-to-late 20s show better long-term stability. Couples marrying after 30 demonstrate strong success rates.
Grey divorce. Divorce among couples over 50 is increasing dramatically. Baby boomers separate at higher rates than previous older generations.
Statistics Canada reported a nearly 80% increase in divorced Canadians over age 65 from 2010 to 2020.
Longer life expectancy makes people less willing to spend 30-plus years in unfulfilling marriages. Financial independence, especially for women, enables grey divorce. Retirement transitions also trigger relationship reevaluations for many couples.
While Canada's overall divorce rate has declined since 1991, later-life marital dissolution presents a distinctive and complex trajectory. Recent data suggests a plateau or even a decline in divorce rates among younger cohorts while grey divorce continues to rise sharply.
Second and third marriages. Remarriages fail at higher rates than first marriages. Approximately 60% of second marriages end in divorce. Third marriages show even worse success rates, often exceeding 70% failure.
Blended family challenges contribute to these higher rates. Step-parenting issues, co-parenting with ex-spouses, and complex family dynamics create additional stress.
Statistics show that around 55% of divorces are initiated by women, a pattern that has remained consistent since 2000.
The 50% myth:
The often-cited figure that half of all marriages end in divorce is a myth. The 50% figure comes from a crude projection method that compares divorces in a given year to marriages in that same year, which are two different populations.
A better measure looks at what proportion of marriages entered into during a given period will eventually end in divorce.
The Department of Justice Canada previously estimated that 40 to 50% of Canadian marriages could end in divorce if trends at the time continued, but more recent data suggests the actual figure is lower.
Common Reasons for Divorce in Canada
Research consistently identifies several leading causes of divorce in Canada. Understanding these reasons can help couples recognize warning signs and seek help before it is too late.
1. Financial Issues
Money is consistently cited as the number one cause of divorce in Canada.
Around 68% of Canadians are sure that disagreements over finances or other property-related issues will be the main cause of divorce. Mismanagement of finances, deficient planning, and debt accumulation are all examples of financial issues that strain marriages.
According to Statistics Canada, more than half of the people currently going through a divorce identified financial difficulties as a reason that contributed to the decision to end their marital relationship.
The financial pressures on relationships have only intensified. A 2025 Love and Money survey by Money Mentors, an Alberta-based non-profit credit counselling agency, found that 47% of Canadians have had financial disputes with their partner. Eleven percent of couples have considered breaking up, separating, or divorcing due to financial stress.
Millennials and Gen X are the most likely to consider it, at 13% and 14% respectively, compared to Boomers at 9% and Gen Z at 6%. Financial-related arguments make 66% of people more anxious or depressed, 26% less patient with important people in their lives, and 23% less productive at work the next day.
Financial disagreements can start with something as simple as different spending habits. One spouse may be a saver who sets goals and thinks about the future, while the other spends excessively in a single day. Over time, these differences reach a point where divorce seems like the only solution.
The cost of moving and paying for lawyers is enough to make many people think twice about breaking up. Some researchers have suggested that Canadians cannot afford to get divorced given housing costs, inflation, other living expenses, and the legal costs of divorce.
Financial infidelity, where one spouse hides spending, debt, or assets from the other, is also a growing concern. If left unaddressed, financial infidelity can lead to ongoing conflict, separation, or even divorce.
2. Lack of Communication and Emotional Connection
Poor communication consistently ranks among the top reasons marriages fail. Yelling, making nasty comments, and expressing yourself poorly will never resolve conflicts. Having the same argument over and over again without resolution creates a cycle of frustration and resentment.
A lack of emotional connection can also lead to the dissolution of a marriage. Couples often experience this when they begin to see their partner as emotionally unreachable or when they feel they are no longer respected. Because of decreased communication and physical touch, both partners may experience feelings of abandonment and neglect. They may be encouraged to seek consolation elsewhere or contemplate ending their relationship.
Calm communication, appreciation for one another, and quality time together are essential for a healthy marriage. Simple dates and spending time at home watching favorite movies can help maintain connection. Presence matters more than anything else.
No matter how busy life gets, finding time to understand your spouse is critical. Couples who make a concerted effort to consistently express feelings of compassion and appreciation toward one another are far less likely to end up in divorce court.
3. Lack of Preparation for Marriage
These situations are highest for couples in their 20s. The lack of preparation is often the reason. Marriage is a decision that changes the rest of your life. It is exciting and romantic, but understanding the real meaning of it before entering into it is essential.
You may think you have planned everything and are ready, but sometimes your current lifestyle and future hopes and dreams do not align. Commitment means having no reservations about marrying your partner. Couples who marry very young face higher divorce risks than those who wait.
Financial stability and emotional maturity at the time of marriage matter tremendously for long-term outcomes.
Education levels also correlate with marriage longevity, with higher education generally associated with lower divorce rates. Life experience and career establishment before marriage provide stronger foundations for partnerships.
4. Physical and Emotional Abuse
Deep emotional issues are sometimes to blame. Marriage is not easy. Sometimes couples with the best intentions end up in courtrooms. Physical or mental cruelty that is severe enough to make cohabitation unsafe, unhealthy, or intolerable is grounds for divorce.
Examples of cruelty include patterns of behavior that make living together impossible.
When things get rough and emotions become a roller coaster ride, talking to an expert before things get worse is the best course of action. Seeking marriage counseling can help ensure that a marriage remains healthy. Even when things are going well, counseling can provide tools for maintaining a strong relationship.
Bill C-223, the Keeping Children Safe Act introduced in September 2025, proposes amendments to the Divorce Act aimed at strengthening how courts address family violence during divorce and custody proceedings.
The bill would impose new requirements on lawyers to screen for signs of family violence during divorce cases and give judges new tools to identify the existence and impact of coercive control on children. It would also require legal advisers who undertake to act on a spouse's behalf in a divorce proceeding to assess the risk of family violence and, if there is a risk, to take steps to implement an appropriate plan.
While the bill is still at an early stage as of 2026, if passed, it would reshape how lawyers, courts, and families navigate divorce-related parenting with a stronger emphasis on safety, child agency, and a nuanced understanding of abuse.
5. Infidelity
Infidelity remains one of the most common reasons for divorce in Canada. It often starts as an emotional affair that soon becomes a physical relationship. Adultery or having an affair while married is a violation of trust. One reason for unfaithfulness is a sense of emotional isolation from a partner.
Infidelity has the capacity to bring about feelings like betrayal, mistrust, and emotional distress. Some people who have experienced infidelity have a tough time regaining their confidence and reestablishing their connection with their spouse.
The act of cheating may result in substantial emotional distress that can have a profound impact on both parties and leave an indelible mark on their lives. Some couples are able to overcome an extramarital affair and repair their married connection despite the difficulties they face. Others believe the damage is insurmountable and decide to end their relationship.
Under Canadian law, adultery and cruelty carry social stigma and tend to increase conflict, which is why courts generally prefer the no-fault one-year separation ground.
However, in cases where an affair has led to substantial and significant financial misconduct, such as one spouse spending considerable money on the affair, the court will likely adjust the division of property. If a spouse has used family money to fund an affair, paying for hotels, gifts, or travel, this could be considered financial misconduct and factored into an equalization payment.
The Legal Process of Divorce in Canada
Understanding the legal framework for divorce helps reduce stress and uncertainty during an already difficult time.
Grounds for divorce. Under Canada's Divorce Act, the only ground for divorce is marriage breakdown. Marriage breakdown is established in three ways: the spouses have lived separate and apart for at least one year immediately preceding the determination of the divorce proceeding; one spouse has committed adultery; or one spouse has treated the other with physical or mental cruelty of such a kind as to make continued cohabitation intolerable.
The vast majority of divorces in Canada proceed on the one-year separation ground because it does not require proving fault and tends to be less adversarial.
Parties may file for divorce on the day of separation, although the divorce cannot be granted until one year has passed from the date of separation. If you apply for a divorce on the basis of a one-year separation, you can live together for up to 90 days to try to reconcile. If things do not work out, the clock does not necessarily reset.
Federal versus provincial jurisdiction. Divorce in Canada is governed by the federal Divorce Act, but everything that matters financially, how property is divided, how much support is paid, and how children are cared for, is set by the province where you live.
This single split is the source of nearly every dispute in this area of law. A couple who married in Ontario, owns a cottage in Quebec, and sends their child to school in British Columbia may simultaneously face the rules of three different jurisdictions. The federal Divorce Act tells the judge whether the marriage has broken down; the provincial code tells the judge what to do about it.
Quebec is a notable outlier. Its Civil Code imposes a mandatory 50/50 patrimony split that cannot be waived, yet excludes common-law partners entirely.
Civil marriage in Quebec automatically triggers the patrimoine familial regime: the family residence, household furniture, family vehicles, pension benefits, and registered retirement accounts accumulated during the marriage are divided 50/50 on divorce, regardless of who paid for them and regardless of any agreement to the contrary.
Even a notarized marriage contract cannot opt out of it.
Common-law partners in Quebec receive nothing, a result the Supreme Court of Canada upheld in Eric v. Lola in 2013.
Alternative dispute resolution. Across Canada, courts have increasingly required couples going through separation or divorce to try resolving their disputes through alternative dispute resolution methods such as mediation and arbitration.
In some provinces, such as Alberta, Ontario, and Saskatchewan, trying ADR methods is now a required step before taking a family law matter to court.
Mediation is strongly encouraged under federal and provincial laws and recommended by family court judges as a means to resolve issues including parenting, child and spousal support, and the division of assets.
In Quebec, five hours of free mediation is mandatory for couples with children as part of a February 2025 reform.
Mandatory ADR has become an integral part of family law across Canada, helping many families resolve their disputes efficiently and with less conflict.
The role of divorce lawyers. Hiring a good divorce lawyer is essential to get things done efficiently and smoothly. An experienced family lawyer will help negotiate the resolution of critical issues before heading to court, reducing stress and ensuring your rights are protected. Lawyers can also help with the mandatory family violence screening that may become required under Bill C-223.
For couples who can agree on the terms of their divorce, a lawyer can help prepare the necessary documentation and ensure the agreement complies with the law. For couples who cannot agree, a lawyer provides representation in court and advocates for their client's interests.
Average duration of proceedings. The average length of divorce proceedings in 2024 was four to six months. Marriages in Canada last, on average, 15 years before ending in divorce. The divorce rate per 1,000 married persons in Canada decreased from 7.5 in 2019 to 5.6 in 2020.
The psychological impact of divorce. During and after divorce, people can sometimes face psychological issues. Some people experience an increase in stress levels and can even suffer from lower self-worth. The support of experienced family lawyers and, when appropriate, mental health professionals can help individuals navigate both the legal and emotional challenges of divorce.
What the Future Holds
Bill C-223, if passed, will represent the most significant change to Canada's Divorce Act since 1985. The bill proposes amendments that would affect how courts assess parenting arrangements, family violence, and children's interests in divorce proceedings.
Key proposed changes include mandatory family violence screening and legal adviser obligations, as well as changes to how courts assess parenting disputes and evidence. The bill is a private member's bill introduced by Liberal MP Lisa Hepfner. Far too few practising lawyers and family law professionals are aware of the bill.
The decline in divorce rates since the 1990s reflects several factors. Younger Canadians are choosing common-law unions instead of marriage, which means separations do not require formal divorce proceedings. The average age of the married population is increasing.
Couples who do marry today tend to be older, more financially stable, and more deliberate in their decision, all factors associated with lower divorce rates.
The rise of grey divorce shows that even as overall divorce rates decline, later-life separations continue to grow. Longer life expectancy makes people less willing to spend decades in unfulfilling marriages. Financial independence, especially for women, enables grey divorce.
Divorce is never easy.
It can be traumatic for everyone involved. But understanding the history, the statistics, the common causes, and the legal process can help individuals make informed decisions and navigate the challenging journey with greater clarity. Whether you are considering divorce, in the middle of the process, or simply trying to understand the landscape, knowledge is power.
The support of experienced family lawyers and, when needed, mental health professionals can make a significant difference in achieving a resolution and moving forward with your life.
