I live in Northern Ontario Canada. It gets damn cold up here.

I have a friend who will make me a plow cheaper than I can buy in stores. (Good to know a professional welder.) Where is the strongest point on the front of the frame?

I probably will park it outside, with a cover over the majority of the bike. Any issues with starting it in the really cold times?
I plan on also getting chains for all wheels.

Any other suggestions for using the bike for plowing my driveway?
