Though the law differs in each province and territory, landlords must usually provide a 90-day notice before increasing rent. In some parts of Canada, landlords can only increase rent on the anniversary of the date you first moved in. They can also increase rent only once a year and only by a maximum amount set by your provincial or territorial government. If the landlord does not provide you with proper notice, you may be able to refuse to pay the rent increase until they provide proper notice.

Renewing your Lease
When you first move into your rental, you probably signed a lease for a fixed term, such as one year. At the end of the year, depending on which province or territory you live in, the terms of your lease may change from one year to ‘month-to-month.’
A month-to-month lease means that after the first year, your lease is now renewed on a monthly basis. Month-to-month lease still provide protection from illegal eviction, but it is easier for you or your landlord to terminate your tenancy provided you give adequate written advance notice, and the proper protocol is followed.
