Canada, it says that the law doesn't apply to us.
I'm in Canada - and while we don't have the ADA here, we DO have a number of similar Disability Rights laws here which function very much like the ADA, the main one being the Federal Disability Act (FDA).
Perhaps you live in a small town where you don't have much exposure to the various laws etc? (or because you're quite young just haven't had experience with them yourself).
Also - to clarify YES, there is a rule (law) stating that an interpreter MUST be provided (if requested) in various situations (medical appointments, schooling, things involving the government/government agency/government programs etc) and that in those situations it must be free to the Hoh/Deaf person. There are situations like private functions where the Hoh/Deaf persons would pay for the interpreter themselves, but they are the "exception, not the rule". It's also the law that "reasonable accommodations" be provided and that legally employers aren't allowed to discriminate against Hoh/Deaf etc.
Information about laws and regulations for those who are Hoh/Deaf, or have a physical or mental disability can be found on the official Government of Canada Website... your audiologist should also be able give you information.

Also, you mentioned in one of your posts (before you deleted it) that you thought that the Deaf schools in Canada were run by the USA - this is not true. There are a number of Schools for the Deaf across Canada -some are private schools (like many religious-based schools are) and some are public schools. Both are just like "hearing schools" in that they have to follow all the education rules and requirements made by each province as well as federally (mad by Canada in general). They are NOT "controlled by", or "run by" or connected to the US in any way, shape or form - they are
Canadian Schools for the Deaf. Period.
