Question

give geographical reasons Canada has 6 different Standard Time

Answer 1

Because Canada is the second biggest country on Earth and needs a lot of time zones to cover the country. The biggest country on Earth is Russia, which has 11 time zones.
Canada extends from the Pacific Ocean to the Atlantic Ocean. Time zones generally change when the time difference is greater than one hour. So Canada’s time zones are Pacific standard time, Mountain standard time, Central standard time, Eastern standard time, Atlantic standard time, and Newfoundland standard time.
I like to call the last, “Newfoundland Substandard Time” because it only differs by half an hour from Atlantic standard time. But that’s just me. The island is only half a time zone wide, so the western end should be on Atlantic standard time, but the capital of Saint John’s is half a time zone east, 30 minutes earlier.
However, in summer most provinces advance their clocks by an hour to take advantage of the longer summer days. The main exception is Saskatchewan which is doesn’t change its clocks and so is on the same time zone as Manitoba in winter, and as Alberta in summer. The Peace River area of BC is similar in that it doesn’t change clocks, so it spends the winter on Alberta time and the summer on BC time.

Answer 2

The size of the country is so big that it spans 90 degree of longitude. And hence, there are six different time zones in Canada.

They are referred to as Eastern Daylight Time. They are,

• Newfoundland Daylight Time  (GMT-2:30)
• Atlantic Daylight Time  (GMT-3)
• Central Daylight Time  (GMT-5)
• Central Standard Time  (GMT-6)
• Mountain Daylight Time  (GMT-6)
• Pacific Daylight Time  (GMT-7)

Reasons:

• The size of the country.
• The longitudinal extent.
• For better understanding of time across the country.
