Eastern Time (Toronto)

Eastern Time in Canada covers the country's most populous province, Ontario, as well as most of Quebec. Toronto, Canada's largest city and financial capital, anchors this timezone along with Ottawa, the national capital. The Toronto Stock Exchange (TSX), Canada's primary securities exchange, operates on Eastern Time in lockstep with US markets. EST/EDT follows the same DST schedule as the US since 2007, switching on the second Sunday of March and the first Sunday of November. Canada adopted standard time zones in 1884, shortly after the US, largely due to the influence of Sir Sandford Fleming, a Canadian railway engineer who is widely credited as the father of worldwide standard time. Eastern Canada's proximity to the US northeast corridor means extensive cross-border business, with many companies operating seamlessly across the Toronto-New York axis. The timezone is also home to Canada's technology sector in Ottawa and Waterloo, the French-speaking business hub of Montreal, and the automotive manufacturing corridor in southern Ontario.
