Just look around, you can find several retailers who will ship to Canada. You can even find the cards in both French and English. If you are having a hard time finding one that will ship, then look on ebay.com
Here is a list of places I know ship to Canada:
starcitygames.com
collecterschache.com
Trollandtoad.com
Bigfireball.com
Mtgstronghold.com
Keep in mind that there are many, many, many more.
Edit: Beware that Wizards has passed a rule that retailers in the US are NOT allowed to ship boosters and booster boxes outside of the US.
thegameshop.ca is one of the only sites I've found, and they don't have much for magic.
There are several places online, including the MTG homepage where you can do a mock booster draft. However there is no program/website licenced or otherwise where you don't have to download anything.
They've sold starter and theme decks, but rarely (if ever) single booster packs.

At time of writing, probably Gatecrash. Aurelia, the Warleader and Aurelia's Fury are huge in terms of value and longevity.
the abbreviation is mtg
The suggested retail price of a booster pack (15 cards - sometimes more) is $3.99. Taking into consideration a margin of profit, I estimate the cost of production for a non-foil, common MTG card to be anywhere from $.03 to $.07. This would allow for Wizards to make profit.
