Welcome from a fellow Albertan!
Those Brew Canada kits are simple and cheap, which makes them attractive to a new brewer. The quality of the beer is not particularly great, but you will end up with beer in the end and you can proudly say "I made this" when you drink it and share it with others. The biggest problem with the kits is the addition of 1 kg of sugar - it will boost the alcohol, but not add much flavour. Corn sugar will ferment completely but won't add any body to the beer. The beers in those kits tend to lack body and flavour. Using DME may help some, but the beer is what it is. If you are used to drinking mass-market lagers like Coors Light, then you will probably enjoy your beer for what it is. If you were hoping for a double IPA or an Imperial Stout, you will find it disappointing.
There are a couple of options for simple kit brewing here in Canada. Festa Brew makes kits that have 23L of pre-made wort and a packet of yeast. Pour the wort into a sanitized fermenter, add the yeast and let it do it's magic. It is a very simple way to brew, and the quality of the beer is very good.
There is another kit out there called Brew House. They have 15L of acidic wort, to which you add in a powder that balances the pH and 8L of water, then pitch the yeast. It seems trickier, but it really isn't. BH kits are also very hackable. For instance, they have an IPA kit that I have heard is pretty good. If you wanted to make it into a more substantial American-style IPA, you could just add 4L of water to the wort and dry hop with Cascade. Use Safale US-05 instead of the yeast that comes with the package. Or, you could steep some Carafa III in with the added water and make a black IPA. Options are there. Their website has a recipe for making a Duvel clone (I made it last summer, and it is very good), and I am currently attempting a Saison from a hacked cream ale kit.
The best advice I can think of, other than watch your sanitation, is to ignore the instructions that came with the kit. You don't need a secondary fermentation, and don't follow a timeline (let the hydrometer tell you when fermentation is done). Even then, give it a few weeks on the yeast cake before you bottle. Then give it at least 3 weeks in the bottle before you crack one open. Let your bottles condition in a warm place, but put them in the fridge a good couple of days before drinking to let the yeast settle out of suspension. You will probably find that the best beer of the bunch is the last one.
Finally, beer done right takes time. Consider getting a second fermenter to fill the pipeline.
