DON'T SHIP UPS FROM THE US TO CANADA!!!!!!!!
Ups charges "brokerage" on cross border items. This is not the taxes and duties you would have to pay anyways, it's a "service fee".
It can be almost as much as the purchase price on your item, effectively doubling the purchase price.
Other couriers are no better, they all charge "extra".
A quick look at UPS site reveals 75.00 for "brokerage". This is on top of your shipping.
Then they charge you a COD fee at the door to collect the brokerage fees.
Then there's always a few more "surprise fees".
Here's a link to their current shipping PDF:

Add to this your duties and taxes.
If you can get it shipped USPS, they do not charge brokerage. Your shipping is what it is, not nasty extras at the door. However, there are limits on size and weight with USPS. Your hitch might be too large or too heavy.
I've shipped UPS from the states before, not a good experience.
It's either USPS or I don't ship in from the states now....
