Where can i calculate additional taxes for bringing expensive goods back home from Canada?

[Darth-Veger]

So i am going to Canada, Toronto this Sunday and i might wanna buy a GoPro Black+ (480 Canadian Dollar) back home but i am having a hard time finding a site or guide that lets me calculate the amount of taxes i need to pay the airport for bringing the thing over back to the Netherlands.
Does anyone have any experience with bringing goods over 60$ over the Canadian border?

Edit: While at it anyway, anyone know if there are stores in canada selling the gopro cheaper? Only site i currently found that has the GoPro is Bestbuy.
