I own a renovation (remodel) company just outside Toronto.
My '51 3100 is a company vehicle and I use it to visit jobs and pick up some material and deliver it to the site.
I write off all my expenses and depreciate the original capital cost of the truck.
Rules may be different in Canada but, I think we generally follow the same rules as you do in the US.
Here they even pay ALL my medical bills - and all my prescriptions now that I am old.
What a beautiful country we live in!!!
Sorry for the editorial :-)
