I'd look into the EU / German laws to confirm the labelling requirements
Since the US-Canada tariffs, a lot of products in Canada have been identifying themselves as Canadian. However, as we're learning now - "Made in Canada" vs "Canadian" is very different. A lot of companies have been touting themselves as "Canadian" when they just have Greg from marketing who mentioned he has a cousin that used to live in Toronto a few years ago. Even "Made in Canada" is a grey area - the product doesn't have to be 100% Canadian to qualify
