No EU countries & VAT charged on upgrade

[BrianT]

So in theory, I have to pay Devialet 20% VAT and then GST to Jersey authorities when the goods are returned.

According to the Email I got back from Devialet they pay the GST (or other taxes) when it is returned to you.

This is the question that I asked:
From this response, it looks like I pay the 20% VAT to Devialet and Devialet pay all the 
import duties and taxes upon return to Canada. 

This is the reply:
HI Brian,
That is correct,
This is the path, you  pay the 20% VAT to Devialet and Devialet pay all the import duties and taxes upon return to Canada. 
Let me know if you have additional questions,
Best Regards,

Brian
