So under General Compliance it says the following:

(4) The person responsible for a business or organization that is open shall ensure that any person in the indoor area of the premises of the business or organization, or in a vehicle that is operating as part of the business or organization, wears a mask or face covering in a manner that covers their mouth, nose and chin during any period when they are in the indoor area unless the person in the indoor area

And then in Section 4 it says this:

(g) has a medical condition that inhibits their ability to wear a mask or face covering;

And then Section 6 says this:

(6) For greater certainty, it is not necessary for a person to present evidence to the person responsible for a business or place that they are entitled to any of the exceptions set out in subsection (4).

So even though Costco has a big fucking sign saying No Mask, No Entry, I can use this clause in Ontario Law to bypass the bullshit?
