If you use jepps, there is a page in there that has the same info. The AIM has it as well. The altimeter doesn't work any differently in Canada. The same correction the AIM says to apply to US procedures is what you use in Canada.
It's in a publication called the CAP-GEN. It should come free if you pick up some approach plates from Canada. (This only applies to the Canada Air Pilot Plates, not Jepp or others) Maybe call up a pilot supply shop or Transport Canada and see if they can fax you the cold air temperature correction chart.
I've seen a picture of it. We used to carry it in my old life because we used to operate in -40 to -50 quite a bit. I remember leaving my truck running for a week and coming back to put it in reverse. The wheels just spun inside the tires. ugh. I don't really miss the cold but it would help in an accident i'm looking at.
