Welcome aboard!! 
Al Simmons is in Hamilton, Lebaron's is in Mississauga.
A cheap but dependable deer rifle is a bigger window than you can imagine... esp. as you haven't defined "economical". But that won't stop us from making suggestions.
The first suggestion I'll make is to put a post in the hunting rifles forum (do an advanced search first, trying words like "deer", "first", newby(ie) etc.). Be specific about what you want it for, where you hunt (conditions and such), price range, do you have a preference for bolt action, or lever, auto... you get the idea.
To start you off, the Stevens modell 200 (under $350 brand new) gets good reviews, but you'll have to put a scope on it. In the same price range you can pick up a good used Marlin 336 or 30A in 30-30. A Winchester model 94 is in this group as well, again a 30-30 or .32 Winchester Special.
As you can see, this is just off the top of my head and not knowing what you're really after.
Try to get over to Al's or some place where you can get your hands on some guns and see what fits you.
Best of luck!!
