When the tenant is given a notice to end tenancy, such as an N4 for non-payment, they do not have to acknowledge receipt of it. They either pay the rent and void the notice, move out, or stay and do not pay the rent. If they do not pay by 14th day after serving notice, you may apply to the Board on or after the 15th day for an eviction hearing. If they pay before your Landlord and Tenant Board (LTB)  hearing, they would also have to pay the filing fee. If they don’t pay, then you should continue with the hearing process to get an order. The tenant may pay after the LTB order is issued but before the Sheriff’s office comes to evict. In this case, the tenant can file a Motion to Stay and have the eviction stopped.
