Buying a home does not give you the right to break your lease in Ontario. If you rent month to month, you can end your tenancy with 60 days of written notice. If you signed a fixed-term lease, you are committed until the end date unless your landlord agrees to let you out early or you assign the lease to a new tenant.
The rules come from Ontario's Residential Tenancies Act, and they apply no matter how good your reason for leaving is. A firm purchase agreement does not change your obligations as a tenant. Plenty of first-time buyers in Toronto learn this only after signing an offer, which is why it belongs on your radar early, alongside the other homework in the first steps to buying a home in Toronto.
How notice works
To end a month-to-month tenancy, you give your landlord Form N9 with a termination date at least 60 days out that lands on the last day of a rental period. Most Ontario leases automatically become month to month once the original term expires, so if your one-year lease ended a while ago, you likely already have this flexibility. During a fixed term you can still serve an N9, but the earliest termination date is the final day of the term.
Leaving a fixed term early
You have three realistic paths. Ask your landlord to sign Form N11, a mutual agreement to end the tenancy. Assign the lease to a replacement tenant, which needs your landlord's consent, though the Act says consent cannot be refused arbitrarily. Or sublet, which gets you out of the unit but keeps you responsible for the rent. There is one useful wrinkle: if you request an assignment and your landlord refuses or ignores you for seven days, you can terminate with just 30 days of notice, even mid-term.
For buyers, the practical move is lining up your closing date with your notice. A typical Toronto purchase closes 30 to 90 days after the offer is accepted, and the full timeline is covered in how long it takes to buy a home in Toronto. Many buyers deliberately keep a few weeks of overlap between closing and lease end. Paying rent and a mortgage for one month costs less than moving twice.
