The 'import fee' is made up of Canadian duty, Canadian sales taxes and a $5 ish service fee to Pitney Bowes who run the program as well as the actual shipping cost.
So the shipping portion won't change and the service fee won't change. But both duty and taxes are based on a percentage of the value of the item.
So yes, the import fees should be lower.
Note that the duty applies to items not manufactured in a NAFTA country. Nothing to do with where you bought it.
And used items are still taxable, although not usually dutiable.
