Lee Enfield, most likely. Welcome to the board!
Given our location, the various models of Lee Enfield are almost certainly the most popular due to so many being available at reasonable prices for so long. That said, all of the Enfields (.303), Mausers (8x57), Swedish Mausers (6.5x55), Springfields (30-06), P14/17 (.303/30-06) and Mosins (7.62x54) are fine for most big game in NA.
Bigger questions are whether you reload (or plan to) and what type of game and where you hunt. Some of the above calibers are not easily available in hunting ammo at any price and all are some version of expensive in commercial ammo.
Not planning on the reloading route right yet. Only hunt deer in Eastern Ontario
Then buy a SPORTERIZED Enfield. They are cheap and plentiful. A full wood military version is not something to bang around in the woods with or cut up to lighten. For 150 bones you could get a sported Lee Enfield and go get the ammo anywhere. Most other milsurps have ammo that is either FMJ surplus and therefore no good for hunting or only really available in reloading your own.
While Recce21 is probably right, I would say that an M38 Swede Mauser in 6.5x55 would be a sweet bush rifle. It is light and handy, the calibre is extremely effective on medium game, recoil is about 1/2-2/3 of the .303 and you can find several different brands of ammo. Ammo isn't as cheap as .303, however, and you won't find it at your local CT or Wal Mart. Just a thought if you wanted to be different and still use a milsurp for your hunting.
OP, are you planning on using iron sights or scoping it?

A scope would be nice at some point, mainly to take advantage of low light conditions as most of the areas we hunt do not lend themselves to "hundreds of yards" kinda shots.
