Key takeaways
  • If you are married, the Divorce Act treats spouses as separated if they have lived apart, and Ontario says this can happen under one roof, with an intention to live separately.
  • An informal parenting plan can be hard to enforce, and enforcing your rights is harder without a written arrangement.
  • Legal decision-making responsibility exists only through a signed separation agreement or a court order.
  • If you or your children are unsafe, safety comes first, and there are options to get help.

Many separated parents cannot afford two homes, or are waiting for a lease, a sale or the end of a school year. Living under one roof after the relationship ends is common, but it raises hard questions about who does what with the children and what it means for your legal position.

This article explains in general terms how separation under one roof works in Ontario and how to set up parenting arrangements while you share a home. It is not advice on your case. If there is any family violence, read the safety section first.

Can you be separated in the same home?

Yes. Under the Divorce Act, spouses are treated as separated if they have lived apart, and Ontario says living separate and apart can happen under one roof, for example with separate bedrooms and separate areas, along with an intention to live separately. Divorce requires at least one year of separation immediately before the divorce is decided.

Which law applies depends on your situation. If no divorce proceeding has started, the Children's Law Reform Act applies and you would need a parenting order under that Act. Whether other issues, such as who may remain in the home, are affected by sharing it is a question for a lawyer.

Setting parenting arrangements while sharing a home

Parenting time and decision-making are separate ideas. Decision-making covers significant decisions such as health, education and religion, and can be sole or joint, while parenting time includes time the child is at school or elsewhere. Joint decision-making needs parents who can cooperate and communicate.

When you live together, it is hard to say whose parenting time it is. A written routine can help: who handles mornings, bedtime, school pickups, activities and appointments. A parent with parenting time has exclusive authority for day-to-day decisions during that time, unless the court orders otherwise. Setting out the schedule on paper reduces arguments about who is in charge at any moment.

Parents have the right to parenting time unless a court decides otherwise. For married spouses under the Divorce Act, courts also give effect to the principle that a child should have as much time with each spouse as is consistent with the child's best interests.

Informal, agreement or order: how strong is each?

Type of arrangementWhat to know
Informal arrangementAn informal parenting plan can be hard to enforce. De facto decision-making exists when the child lives with you full-time, you live separate and apart, and the other spouse accepts this
Separation agreementA plan can be part of a separation agreement. Legal decision-making responsibility exists through a signed separation agreement or a court order
Court orderIf parents cannot agree, either can apply for a parenting order, and the judge must act in the child's best interests and consider family violence

If you agree on a parenting plan and it becomes part of a court order under the Divorce Act, the court must include it unless it is not in the child's best interests, in which case the court may modify it. Enforcing your rights is harder without a written arrangement. Because you share a home, a fully de facto arrangement may not fit, since the child is not living with only one of you.

Protecting your position and your children

Sharing a home does not stop you from asking a court for a parenting order. For married spouses under the Divorce Act, a court can make parenting orders, including interim orders, that set schedules, conditions and supervision. Practical steps still matter.

Under the Divorce Act, a person with parenting time or decision-making responsibility can ask others holding information, such as health and education providers, for information about the child's well-being, unless the court orders otherwise. How this applies if you were never married depends on your situation, so it is worth confirming with a lawyer.

If it is not safe at home

Staying together for money reasons should never mean staying unsafe. Family violence includes physical, sexual, psychological and financial abuse and harassment, and conduct that causes someone to fear for their safety, whether or not it is a crime. If you leave an abusive situation you can still apply for parenting of your children, and if the children might be in danger you can contact police to take you to a shelter or safe place.

Justice Canada notes that separation can be a particularly dangerous time and recommends a safety plan for you and your children where there is family violence. A motion can be brought without notice in limited situations, including where there is immediate danger that a child will be removed from Ontario or to someone's health or safety and delay would probably have serious consequences. After a without-notice order, you usually must return to court within 14 days so the other party can respond.

What to do next

Decide what you can realistically agree on, put it in writing, and get legal advice about turning it into a separation agreement or a consent order. If you cannot agree, a parenting order is the next step. If safety is a concern, make a safety plan first.

Frequently asked questions

Do we have to move out before we are legally separated?

No. Living separate and apart can happen under one roof, with separate bedrooms and areas and an intention to live separately. For a divorce, at least one year of separation immediately before the divorce is decided is required.

Is a verbal parenting schedule enough?

It can work while you cooperate, but an informal plan can be hard to enforce. Legal decision-making responsibility exists only through a signed separation agreement or a court order.

What if we were never married?

Which law applies depends on your situation. If no divorce proceeding has started, the Children's Law Reform Act applies and you would need a parenting order under it. A lawyer can confirm how this applies to you.

What if I fear for my safety at home?

Contact police if the children might be in danger, and they can take you to a shelter or safe place. A lawyer can explain urgent court options, including a motion without notice in limited situations such as immediate danger that a child will be removed from Ontario or to someone's health or safety.
