Can I find out if a business is actually compliant with Ontario's accessibility rules?

This is generally something you assess directly rather than through a public compliance database, since accessibility compliance depends heavily on the specific business — its size, the nature of its customer-facing operations, its premises, and its policies — and there isn't a simple public lookup that confirms current status the way a corporate registry search does.

Practically, this means reviewing the business's own accessibility policies and training records where required, walking through its physical premises with accessibility requirements in mind, and reviewing its website and customer-facing materials if those are part of what you're acquiring. Requirements can differ depending on the size of the organization, so what a small operation needs to have in place can look quite different from what's expected of a larger one.

Ask the seller for whatever accessibility policies, training documentation, or premises accommodations already exist, and have someone knowledgeable review both the physical space and any customer-facing digital properties against current requirements before closing, rather than assuming compliance because the business has operated without complaint so far. Non-compliance found after closing becomes your responsibility to fix as the new operator, regardless of whether the seller ever addressed it. A Treadstone business lawyer can help you understand which specific requirements apply to a business of your size.
