Under the Ontario’s Residential Act, a tenant has the right to reasonable enjoyment of the rental unit. Having an open house every weekend for the purposes of selling the property – though inconvenient – is well within the landlord’s right provided they have given you 24 hours notice. However, you still have the following rights:
You are not obligated to leave the premises during showings You are not obligated to leave the premises during showings
You are not obligated to stage the rental unit
You are not obligated to keep the unit in the tidiest state; however, it must be tidy and clean
You may continue to live your regular life during showings; e.g. if it happens at lunchtime you can choose to continue to have lunch as a family
Having said all of the above, it really is in your best interest the owner sells the place as soon as possible to minimize disruptions to your family due to the house sitting on the market for an extended period. For example, if you are in the unit while the open house is happening then potential buyers will feel uncomfortable and less likely to buy. If you maintain your unit in disarray it will show badly and won’t sell. This will translate to keeping the house in the market, schedule more viewings and schedule more open houses, and a very unhappy family.
Be cautious of how you act. Interfering with the landlord’s rights is basis for eviction so do not do anything that can jeopardize a sell.
Collaborate within reason (you don’t have to go out of your way though), keep your place tidy, leave during open houses, and learn to ignore visitors. It’ll all be over soon.
