If the refurbishment or renovations at your rental property are extensive and require your tenant to vacate, how much notice must you give?

The answer is 90 days but this only applies to periodic tenancies. You cannot give notice to a tenant on a fixed term tenancy to move out because you want to renovate.

The renovations or refurbishment must be of such a nature that the tenant couldn’t continue to live there. Replacing the toilet or putting in a new carpet may not be sufficient reason to have your tenant move out.
