Can You Be Separated While Still Living Together in Ontario?

In Canada, living together before marriage is common.  Living together after separation, on the way to divorce?  Not as common.

Or maybe it’s becoming more so.

With tough economic times, an unstable job climate, and high housing costs, many struggling couples have opted to stay living together, even though they have decided to end their marriage.

If this describes you, then it’s important to understand what it might mean to your eligibility to get a divorce. Because under the Canadian Divorce Act, one of the most-used grounds for qualifying for a divorce is that you and your Ex have lived “separate and apart” for at least one year.

That means you have to settle on an official separation date.  And believe it or not, you can still be legally “separated” even while you are still living together under the same roof – it’s just a lot harder to prove to the Divorce court.  So here’s what you need to know.

Separation is About the Breakdown of Relationship – Not Just Where You Live

Living “separate and apart” is more than just physical separation, and “separate” doesn’t necessarily mean separate homes.  In fact, as mentioned you can live in the same home and still be legally separated.

A legal separation refers to the end of your conjugal relationship, meaning the mutual rights and obligations that define your marriage.  It’s about whether one or both of you have withdrawn from the marriage with the intention of ending it.

Ontario courts have repeatedly emphasized that this is a highly fact-driven inquiry. There is no single test or checklist that determines whether separation has occurred. Instead, courts look at the “global” circumstances of the relationship — how you actually live your lives day-to-day.

Troubled Marriages are a Bit Tricker to End, in Law

Maybe you’ve had a rocky marriage for a while – with lots of separations and reconciliations.  Now, you’re both set on divorce.   Settling on a separation date that satisfies the court is a little bit harder and a bit more uncertain in these circumstances.

This was the scenario before the Ontario Court of Appeal in Kassabian v. Marcarian, 2025 ONCA 239, which shows why the date of separation can remain uncertain even where a marriage has been troubled for years.

In that case, the husband claimed the parties had separated in 2014, when they stopped sharing a bedroom but still lived in the same home. The wife said the marriage, though unhappy, continued until 2021, when she clearly said she wanted to separate and then confirmed that intention by email.

The trial judge accepted the wife’s version, and the Court of Appeal upheld that result.

The Court emphasized that a marriage can be unsatisfying, emotionally distant, or quite different from what the parties once expected – all without having legally ended.  Marital unhappiness is one factor, but it’s not the only one that determines when a marriage ends.  Rather, it’s necessary to consider the entire relationship, including:

• Whether the parties continued to share family routines,
• How they handled finances,
• How they presented themselves to others,
• Whether they took legal or formal steps toward separation, and
• Whether there was any real prospect of reconciliation.

The Key Factors That Establish “Separation”

The Court in Kassabian went on to provide a more thorough blueprint for how the date of separation is determined in any Canadian divorce case.  Here are the key points:

• Separation is about the relationship, not just where you live. You can be “separate and apart” even under the same roof, but only if the marital relationship has truly ended.
• At least one person must intend to end the relationship. You do not both have to agree. One spouse can decide the marriage is over.
• That intention must be clear and communicated. Courts look for a clear statement or obvious conduct showing the relationship has ended. You cannot “separate in secret.”
• Courts look at the whole picture. There is no single test. Judges consider all the circumstances together, not just one factor.
• The key question is: What changed, and when? The court focuses on the shift from married life to separate lives — not just whether the relationship was unhappy.
• Living separate lives matters more than living in separate homes. Courts look at whether you have stopped functioning as a couple in daily life.
• Day-to-day behaviour is important. This includes many straightforward indicators of whether you and your Ex have the required intent to separate.
• Financial separation is also important. This is one of the key telltale signals that you have opted to end your relationship.
• How you present yourselves to others matters. It is relevant whether you tell friends, family, and institutions (like the Canada Revenue Agency) that you are separated, and whether you still present yourselves as a couple.
• Taking formal steps helps show separation. Speaking to a lawyer, preparing a separation agreement, or starting legal processes can support your position.
• Attempts to reconcile are considered. Genuine efforts to get back together may delay the separation date. Casual or half-hearted discussions usually will not.
• The court looks at your real behaviour, not just what you say. If your actions do not match your claim that you are separated, the court may reject your position.
• Every relationship is different. There is no “one-size-fits-all” checklist. The court looks at how your particular relationship functioned.
• Separation is often a gradual process. Many couples drift apart over time. Even so, the court must still identify one specific date when separation legally occurred.
• The separation date matters — and it can be disputed. Because the separation date affects property division and support under the Canadian Family Law regime, courts examine the evidence carefully where spouses disagree.

How-To: The Practicalities of Living Separate Under One Roof

With these principles from Kassabian in mind, here’s a little “how-to” guide on day-to-day tasks, aimed at helping prove to the court that you and your Ex are no longer functioning as a couple:

• Living arrangements
  Move into separate bedrooms.
  • End the intimate/sexual relationship.
  • Stop sharing personal space the way spouses normally would.
  • Keep personal belongings separate where possible.
• Daily routines
  Stop functioning as a household “team.”
  • Stop eating meals together.
  • Stop cooking for each other.
  • Stop doing each other’s laundry or household chores.
  • Handle your own day-to-day domestic tasks independently.
• Finances
  Separate your financial affairs.
  • Open and use individual bank accounts.
  • Stop pooling income.
  • Stop paying household expenses jointly where possible.
  • Pay your own personal expenses going forward.
• Social life
  Stop presenting yourselves publicly as a couple.
  • Attend social events separately.
  • Stop vacationing together.
  • Celebrate holidays separately.
  • Do not jointly mark anniversaries, birthdays, or other milestones.
• Communication
  Limit communication to practical matters.
  • Focus discussions on children, schedules, or household logistics.
  • Stop sharing personal plans, problems, or emotional support.
  • Avoid maintaining the kind of emotional partnership typical of a marriage.

While this list is not exhaustive, it gives you the flavour of the type of changes to your relationship that the courts expect to see, before they will grant your divorce.

The Social and Emotional Factors

It’s not just the daily logistics that courts will look at; the social and emotional aspects of your relationship count too.  The courts will assess whether you have withdrawn from the interpersonal and social components.

To support your separation date, you need to essentially act like you are already divorced.  In particular:

• Don’t celebrate anniversaries, birthdays, or holidays together, and don’t exchange gifts.
• Let it fall to others to support your Ex through any illnesses or personal difficulties.
• Avoid socializing together when seeing friends or extended family.
• Don’t present yourselves publicly as a couple, at places like church, your children’s school, or at social events.
• Avoid all joint social activities with friends and neighbours.
• Do tell your children, family and friends groups about the separation (assuming it’s otherwise appropriate to do so).

None of these steps are legally mandated, but they help provide persuasive evidence that the relationship has ended.

Intent is the Key

One of the most important elements of separation is intention. At least one spouse must have formed a clear intent to end the marriage, and must act in accordance with it.

Surprisingly, you both don’t have to agree. One of you can decide that the relationship is over, even if the other disagrees. Nor does it require a formal declaration (in writing or verbally), although clear communication is extremely helpful to establish a separation date. Courts will look for decisive acts or statements – for example a conversation or correspondence between you, indicating the relationship is over.

It’s also important to know that brief or unsuccessful attempts at reconciliation do not necessarily interrupt a period of separation. The law recognizes that relationships can be complex, and that you may struggle with your decision before separating for the final time.
