Best bet is to go to the site and see.
I just did that and the prices are in usd (United States dollars).
There is a little German flag in the upper right web page corner that drops down and switches to a German language webpage and pricing.
If you purchase a product then somewhere along the way there will be a currency conversion made for you - maybe via use of a credit card.
Probably easy to find a currency calculator if you need Canadian pricing beforehand.
You could call or email them and ask about the conversion.
