There are 6 standard time zones in Canada and 4 of them are the same as in the USA. Legally all matters concerning local time are officially regulated by the provincial legislation and decisions of the municipalities, that's why in practice many exceptions apply in some provinces.
- UTC-03:30 Newfoundland Time Zone includes the entire island of Newfoundland and the southeastern part of the Labrador region.
- UTC-04:00 Atlantic Time Zone comprises most part of Labrador and other 3 provinces - New Brunswick (NB), Nova Scotia (NS), Prince Edward Island (PE).
- UTC-05:00 Eastern Time Zone encompasses the eastern part of Nunavut (NU), most of Ontario (ON) and Quebec (QC) provinces.
- UTC-06:00 Central Time Zone includes entire Manitoba (MB), Saskatchewan (SK) with small exception and a rather big portion of Nunavut (NU).
- UTC-07:00 Mountain Time Zone comprises wholly Alberta (AB), Northwest Territories (NT), the western part of Nunavut (NU), the small exception in Saskatchewan (SK), the eastern and southeastern districts of British Columbia (BC).
- UTC-08:00 Pacific Time Zone covers most of British Columbia (BC) and entire Yukon (YT).
Almost all the provinces of Canada apply the Daylight Saving Time (DST) in the warm period of the year, excluding the most territory of Saskatchewan (SK) and some exceptions in British Columbia (BC), Ontario (ON), Quebec (QC) and Nunavut (NU). The DST schedule in Canada is synchronized with the USA.
