If you fly non-stop across Canada from Newfoundland in the east to British Columbia in the west, you can arrive before you set out, that is, by the time shown on clocks in British Columbia. Canada is such a big country that people in British Columbia may be having their breakfast while those in Newfoundland are perhaps already beginning their lunch. So the country is divided into five time zones, each an hour behind in time from the west zones to the east. For example, when it is 12 noon Atlantic Time in Newfoundland and the Madritime Provinces, it is 11a.m. Eastern time in most of Quebec and Ontario. Winnipeg, Manitoba, lies in the middle of the Central Time Zone, here it is 10 a.m. In most of the Prairies and the eastern half the mountains it is 9 a.m. Mountain Time while the west coast region has Pacific Time and it is 8 a.m.
