Give geographical reasons:

Canada has 6 different standard times.

Canada is one of the biggest countries in the world. It ranges from 52° W to 141° W. Thus, the local time in the east is nearly 6 hours ahead of the west. If Canada had selected a time single time zone, then both east and west Canada would be offset from local time by 3 hours. Then, eastern Canada would experience noon by 9:00 AM and 3:00 PM in western Canada. Thus, Canada has gone for multiple time zones. From west to east the time zones are Pacific, Mountain, Central, Eastern, Atlantic, and Newfoundland.
