Like in the US, Canada's time zones are often referred to by their generic name, without making a difference between standard time and Daylight Saving Time designations. For example, Central Time (CT) refers to Central Standard Time (CST) or Central Daylight Time (CDT), depending on which is currently in use.
Note: Local time in these time zones changes when Daylight Saving Time begins and ends.

The above time zones are used during other parts of the year. They will become active again after the next clock change as Daylight Saving Time begins or ends.
Not all areas in Canada observe DST. They include most of Saskatchewan, some locations in Québec east of 63° westerly longitude (e.g. Blanc-Sablon), Southampton Island, and some areas in British Columbia.
Newfoundland, in Canadas most easterly province Newfoundland and Labrador, follows its own time zone. The standard time is Newfoundland Standard Time (NST), which is UTC-3:30. Newfoundland Daylight Time (NDT), the island's Daylight Saving Time, is UTC-2:30.
The reason for the unique 30-minute time zone is twofold: In terms of solar mean time, Newfoundland is located almost exactly 3.5 hours from Coordinated Universal Time (UTC) which is based on the prime meridian (0° longitude). The second reason is that Newfoundland was a separate dominion when time zones were established in Canada.
