There are a number of US online stores that give Canadian prices, taxes, sometimes duty and generally make life easy.
Cabelas, just ordered my new duster, they already worked out tax, duty and broker.
Tigerdirect.ca for computer stuff.
Barnes and Nobles will do most of the Canadian taxes, too.

Don't gloat too much, though, we live in an export based economy. Manufacturing is taking a kicking with the dollar rise. Most companies want to see at least an $8 dollar wage differential and that's going fast, and taking jobs with it.

And no, without ruffling feathers, I don't want a continental monetary unit. We don't have a strong enough recognized national identity unlike the countries of the EEC. We will be absorbed into the US Borg and, no offense, I don't want that. (and please don't go on a tear with that comment.)
