So i have being researching gas masks and so far it seems to me that they are legal in Canada with the exception of wearing them during riots or public protests.

First of all, am i correct in this assumption?

Assuming the above is true, i am having issues finding a supplier in Canada...i have reached out to a couple and was told they only sell to LEO/Military. Are there any good Canadian sources for NEW (not surplus) masks?

Are gas masks ITAR? Can i order one from the US? Again, who are good sources?

I really like the AVON it still being produced? Most places show out of stock although there are surplus ones available here and there.

Any thoughts on the AVON FM12 and AVON C50 specifically? Any other recommendations?
