Why would an Ottawa owner ask TSSA to cover a home stair lift?

Ontario Regulation 209/01 exempts stair lifts in private dwelling houses from TSSA oversight, unless the owner asks in writing for the regulation to apply. That opt-in exists.

What the opt-in means

We found no official source that explains why an owner would make that request. What the sources do say: when a device is regulated, TSSA describes its role as reviewing design submissions, licensing elevating-device contractors and mechanics, inspecting, and investigating incidents. The Regulation also does not apply to lifts for persons with physical disabilities that rise 600 mm or less and are not accessible to the general public. TSSA's own page notes that exempt devices may still be regulated by other entities.

Whether a home that is rented, shared or partly open to the public counts as a private dwelling house is decided by TSSA's questionnaire.

If you are weighing whether to opt in, the right starting point is TSSA's questionnaire about your premises, and then a direct conversation with TSSA about what registration and inspection would involve for your specific lift and home.

If you are looking for Ottawa contractors who do stair lift installation work, the request form on this page sends your details to contractors listed in the Ottawa Construction Network directory.
