> If you go to a Canadian hospital wearing an N95 these days there's a good chance they will insist you to take it off in favour of a "clean" surgical mask with gaps around the sides and nose.

Wouldn't that just be because of protocol, ie. they don't know if you, a member of the public, actually have a legit N95 mask, or if you know how to correctly implement it, etc.

actually have a legit N95 mask

Incidentally, if you want to validate 3M N95 masks, 3M has a web site for that.[1] You type in the code on the bottom of the box and 3M checks it. You can only do this once per code; the site will tell you if a valid code has been used before. They suggest signing and dating the box after doing this, to indicate that check has been done.

Is a surgical-mask better than a fake N95 mask?

How do they know that one is not wearing a fake surgical mask then? The obvious conclusion is that parts of the medical establishment are still being dumbasses about masks, two years into the pandemic.
