Thank you for your sharing. While the box and manual should be accurate with the information, I would rather check with the FCC and Industry Canada filings to be absolutely sure. It is because there have been exception...
Anyway, both FCC and IC filings show the Nokia Lumia 920 (RM-820) is indeed supporting the UMTS Band IV (AWS) that used by WIND, Mobilicity and Videotron, as well as LTE Band 4 (AWS) that used by Rogers, Bell and TELUS.
