What happens if my landlord doesn't give proper notice?

It's likely invalid. In Ontario, a Notice of Entry without 24 hours notice can be challenged at the LTB. A rent increase notice with insufficient notice is void. Document the violation in writing.

Does the notice period include weekends and holidays?

Yes, notice periods are calendar days, not business days, unless your provincial law specifies otherwise.

Can I waive the notice period?

In most provinces, you can agree to a shorter notice period in writing at the time the notice is needed (not in the lease). Pre-signed lease waivers of notice rights are generally unenforceable.

What's the difference between notice to end tenancy and an eviction notice?

A notice to end tenancy gives the tenant a deadline to vacate. An eviction order comes from a tribunal after the landlord applies. The landlord cannot physically remove a tenant without a tribunal order — even after a notice period expires.

Do notice periods differ for fixed-term vs month-to-month leases?

Yes. Month-to-month tenancies have clear notice rules. Fixed-term leases typically end automatically unless renewed — the landlord doesn't need to give notice to end a fixed-term lease in most provinces, but must give notice if they want the tenant to vacate at end of term.
