Daylight Saving Time was implemented in Canada in 1915 to reduce coal consumption and to extend daylight hours for factory work to aid in the war effort.  Since 1945, legislating Daylight Saving Time has been left to the provinces.  In 1952, 54% of British Columbians voted in favour of a plebiscite (a direct public vote) to introduce Daylight Saving Time.

Since the late 1960s, DST observance in Canada has been closely or completely synchronized with the United States.  Most jurisdictions in Canada and the U.S. move their clocks ahead (“spring forward”) by one hour on the second Sunday in March, and “fall back” by one hour on the first Sunday in November.

Some communities in the northeast and southeast regions of the province have adopted Mountain Standard Time (or Mountain Daylight Time) to align with Alberta for all or part of the year.

The last time B.C. conducted a public consultation on Daylight Saving Time was in 2007 and resulted in over 4,000 responses. The vast majority of respondents (92%) were in favour of changing the timing of B.C.’s observance of DST to align with practices in United States and other Canadian provinces.  A relatively small number (approximately 10%) of respondents favoured abolishing the time change and observing either Standard Time or Daylight Saving Time year-round.
