Your Canadian certificate does not say Private Glider or Commercial Glider?
I had not seen that before.

In the most countries of this world, the glider pilot license does not
say "private glider" or "commercial glider", because in most countries
of this world, there is simply no such thing. There's a glider pilot
license, and that's it. A fully ICAO compliant glider license, by the way.

So I think you should try and get some paper by the Canadian authorities
confirming that your licence is ICAO compliant.
