All items do not have import charges.
Any item with a value of over $20.00 Canadian is subject to Canadian taxes
whether they are new or used. And whether they com from USA or somewhere
else outside of Canada.
If shipped by USPS many times items with a value over $20.00 are not
checked by customs.
Many US sellere are now using the Global shipping system wheras they collect the taxes
due and forward them to Canada .so items with a value over $20.00 do not slip by
this method of shipping.
