You are dong the right thing thinking about this in advance instead of fretting over it after the game is on the ground.
The Advice given so far is very sound. I would also recommend something smaller for your First big game animal also.
The only thing I would add to the advice given would be to look at the closest town to your planned hunting area for a local butcher/game processer. I don't know Canada, but you can contact the local Chamber of Commerce (or your version of that organization) and ask for a list of them. Use the internet, phone book, or if close enough take drive there and look for one. As mentioned Elk and Moose are Big critters and those quarters will hold a lot of heat. Getting the meat properly cooled and cared for will make a huge difference in the end product you put on the table.
