Dave,
If you have $400 CDN to spend I recommend you try to find a good used Mexican Strat or Tele. You could also go with a Squier. Guitars dont go bad, so used is always a nice way to get more for the buck. You're in Canada? Check your PennySaver, local classifieds, Tri-Ad type publications.
I'm betting that if you go too cheap, you'll want a better guitar fairly soon, so you may as well get something pf reasonable quality to start with. That is what I found anyway. I wanted a better guitar after only a few months of practicing.
Everyone is going to have different opinions on what you should get. Spend some time thinking about what you want and research prices typical (even check Ebay although with an impoverished Canadian salary you are not likely to find a lot good deals vs. what you could find locally).
My preference leans toward Fender, but to each his own. It IS hard to go wrong with a realy Fender/Squier Strat or Tele, especially if you end up calling the electric guitar quits and you want to sell it.
What kind of music do you want to play? Amps are as hard to recommend as guitars, but initially you can probably get away with a really cheap solid state practice amp to hone your chops. It probably doesnt matter until you want to start jamming with drums and bass. Then you need some more power.
My leaning is toward low to medium wattage tube amps. In time, you may want to check a tube amp out (although they can be more expensive to buy and operate than solid state). Varieties are numerous, but there are still some good vintage values in Canada - 70's silverface Fenders with reverb (choice#1 in my book), Traynor, Peavy Classic series.
As a new guitar player you ABSOLUTELY need a tuner. Little sounds worse to me now than a badly tuned electric - I am nearly a tune-aholic. Virtually any cheap tuner is fine, until you get playing live and need some more versatility.
Of course you will also need a strap, extra strings, cord, picks (unless you're finger dude).
You could consider a capo. It is not essential, you will learn bar chords anyway.
A book of somekind as a reference for chords.
Good luck...and most importantly have a lot of fun.
