How do you intend on keeping the product cold? A refrigerator? A tub of ice?
How long do you expect the keg to last?
You can't use a hand pump unless you plan on dispensing the keg in 1 day. If you want to keep the keg on tap for any period of time, you'll need a beer gas (Nitro/Co2 mix) for the guinness, a nitro regulator to regulate the beer gas pressure, gas line from the regulator to the coupler, beer line from the coupler to a stout faucet. In the beer equipment store, here, there's a stout tapping kit.

It does not include the coupler, or the gas tank. The coupler, you can get, it sounds like. You would have to find a local gas supplier to see if you can get beer gas. (75% nitro/25% co2).
You'd have to check with Canadian customs regarding duty fees. Those fees aren't charged by MicroMatic. Those fees are charged to you by your government.
