Where, in Canada, might I find a set of .22LR headspace gauges?

I never found the need for them. I just have an assortment of different brand shells I try to make sure it will close on. 22LR ammo varies a lot in dimension and in general application isn't that critical on headspace. I have seen target grade guns that wouldn't close on certain brands of ammo.
 
I ordered my go and no go gauges from Brownells. No issues getting them. I'm not aware of availability from a Canadian supplier although it's possible one or more of them could order it in for you.

Not a particularly hard set to make for your own purposes, given that all the features are essentially cylindrical, and about the only critical part is the thickness of the rim.

Make them of brass, for all that you will be using them. They will outlast whoever inherits them, as they are not expected to be able to withstand ill handling by the cheap help in a shop where the guys are not careful handling stuff!
 
RDSC has Shield Rifleworks go and no-go for 22LR. You will crap yourself when you see the price. $90 each

Hirsch Precision has Forsters for $49 each

Why would a No-Go headspace gauge be a waste of money? Doesn't it tell you that if the bolt closes on it, you've got excessive headspace?

Excessive headspace with a .22 rim fire - you will have misfires and those that fire will have a very bulged case at the rear...

Normally a rim fire barrel is fitted so that the bolt contacts the rear face of barrel and the chamber rim is not cut deeper into the barrel. The headspace is built into the bolt face...

but for a gunsmith chambering and fitting barrels to minimum specifications a no go gauge is not required. It is all done with a go gauge.

It s true if the bolt will closes on a no go gauge you have excessive headspace but it still may be safe to use. If it closes on a field gauge it is no longer considered safe to use. The military use 3 gauges - go, no go, field.

I guess I should say that as someone who fits metal parts together for a living, I personally don't usually drop money on a nogo gauge. It's just too easy to stick a shim on the back end of the go gauge, and Bob's your uncle.
Thread gauges are a different thing altogether. I have cut more threads than I care to remember, and I still remember the first time using a set of go nogo ring gauges. The realization that I didn't to have use the wires and a mike on that thread was thrilling!
