Do you split everything 50/50 when you separate in Ontario?

No. Ontario does not divide your assets down the middle. Each spouse calculates their net family property — what they own at separation, minus debts, minus their net worth on the marriage date, minus excluded property. The spouse with the higher number pays the other half the difference. You share the growth built during the marriage, not the whole pile.

What is net family property in Ontario?

Net family property is the measure used to divide property after a married couple separates. You take everything you own on the separation date, subtract the debts you owe that day, subtract your net worth on the day you married, and subtract any excluded property. The result is your net family property. Your spouse calculates theirs the same way.

Does the matrimonial home get divided differently in Ontario?

Yes. The home you were both living in on the separation date is the matrimonial home, and it gets no marriage-date deduction. If you owned that home before you married, its full value on the separation date counts — you do not get to subtract what it was worth on your wedding day. For men who owned a home before marrying, this is the most expensive surprise in the system.

What property is excluded from equalization in Ontario?

Excluded property stays yours and is not shared: a gift or inheritance from someone else received during the marriage, a personal-injury settlement, a life-insurance payout, and anything you agreed in writing to keep out. The protection only holds if you can trace it and kept it separate — mixing it into a joint account or the family home can erase it.

Do common-law partners divide property the same way in Ontario?

No. Equalization of net family property applies only to married couples in Ontario. Common-law partners have no automatic right to an equalization payment, and dividing what they own runs on a different, harder set of rules. If you were not married, get advice specific to your situation before agreeing to anything.
