Jepp CA19

The Cold Temp correction chart is published by Jeppesen. It's page CA19, but I believe you have to have a Canadian subscription to get it.

The link posted by Mike Jenvey appears to be correct (I didn't check all the values), but it doesn't have the text to clarify how it's used.

In a nutshell, if you "hear" the altitude, i.e., an altitude given by ATC, fly it without correction. They've already done the math.

If you "read" it, i.e., from a Jepp chart, then you must apply the corrections.

In the USA, the AIM now has a section on cold weather altitude corrections.
