Android,
I may be the only one who still uses an old two burner Coleman stove.  I bought my stove in about 1974.  Other than getting a new pump for the generator everything still works.  It is heavy, but provides a stable cooking surface and two burners can be convenient.  For a week with 4 guys, I would fill the tank on the stove and bring an extra gallon.  I just use a one gallon plastic gas can you can buy at Wal-Mart, Target or Menards for a couple of bucks.  To portage just carry the stove in one hand and the gas can in the other and a large pack on your back.  You need to bring a funnel to fill the tank.  You don't pack the gas in anything,  Just put the gallon container on the bottom of your canoe.
I highly recommend that you bring two small cigarette lighters and not rely on matches.  I have found that on rainy, damp days that matches are hard to light.  You can still bring matches, but use the lighter to light the match.  Then use the match to light your stove.

The biggest waste of gas is continuing to heat water after it is hot.
