If I had a question I live in Germany and if I were to play on a canada server which ping would I have?

A Twitch streamer lives in Canada wanted to play with him so I ask what ping I have there

That depends on several things:

The game
Server quality
place of residence
Internet connection

And there's no general answer at all. 😉

With luck about 120 ms more than to a server in Germany, so probably about 150 ms. With bad luck, however, also significantly more, that can't be precisely predicted.
