Canada, with its vast geographical span, operates within six distinct time zones. Here’s a comprehensive guide to help you navigate these time zones and understand the local time in different parts of the country.
Time Zones in Canada
From west to east, Canada’s six time zones are:
Pacific Time Zone (UTC -8)
This time zone includes parts of British Columbia, the Yukon, and a portion of the Northwest Territories. The standard time is Pacific Standard Time (PST), and during Daylight Saving Time (DST), it becomes Pacific Daylight Time (PDT)[1][2][4].
Mountain Time Zone (UTC -7)
This zone covers Alberta, most of British Columbia (except the Kitimat-Stikine Region), the Northwest Territories, and parts of Nunavut. The standard time is Mountain Standard Time (MST), and during DST, it becomes Mountain Daylight Time (MDT)[1][2][4].
Central Time Zone (UTC -6)
This time zone includes Manitoba, Saskatchewan, parts of Ontario (western region), parts of Quebec (around James Bay and Hudson Bay), and the Kivalliq Region of Nunavut. The standard time is Central Standard Time (CST), and during DST, it becomes Central Daylight Time (CDT)[1][2][4].
Eastern Time Zone (UTC -5)
This zone encompasses Ontario (except the western part), most of Quebec (except the areas around Estrie, James Bay, and Hudson Bay), and the Kitikmeot and Qikiqtaaluk Regions of Nunavut. The standard time is Eastern Standard Time (EST), and during DST, it becomes Eastern Daylight Time (EDT)[1][2][4].
Atlantic Time Zone (UTC -4)
This time zone includes Nova Scotia, New Brunswick, Prince Edward Island, and most of Quebec (except the area around Estrie). The standard time is Atlantic Standard Time (AST), and during DST, it becomes Atlantic Daylight Time (ADT)[1][2][4].
Newfoundland Time Zone (UTC -3:30)
This unique time zone is specific to Newfoundland and Labrador. The standard time is Newfoundland Standard Time (NST), and during DST, it becomes Newfoundland Daylight Time (NDT)[1][2][4].
Daylight Saving Time (DST)
Canada observes DST, which typically begins on the second Sunday in March at 2:00 a.m. local time and ends on the first Sunday in November at 2:00 a.m. local time. During DST, each time zone moves one hour ahead of its standard time[1][4][5].
Time Zone Boundaries and Adjustments
The time zones in Canada were established based on geographic location, political boundaries, and transportation and communication needs. Over the years, these boundaries have been refined to better suit regional needs. For example, the time zone boundaries in Quebec were adjusted in 1966 to account for the unique geography of the James Bay and Hudson Bay regions[2].
Important Facts
Number of Time Zones: Canada has six standard time zones and six corresponding Daylight Saving Time zones[1][2][4].

Exceptions to DST: Some areas in Canada do not observe DST, including parts of British Columbia, Saskatchewan, and the Yukon Territories[4].
Understanding these time zones and their adjustments for Daylight Saving Time will help you accurately determine the local time in any part of Canada.
