About London Time Zone
London, Ontario uses the IANA timezone America/Toronto, the same timezone database entry used for Toronto and much of southern Ontario. Its standard time is UTC-5 under Eastern Standard Time (EST), and during daylight saving time it changes to UTC-4 under Eastern Daylight Time (EDT). Because London follows the Toronto timezone rules, it changes clocks on the same dates as most of Ontario and the eastern United States.
Daylight saving time in London begins on the second Sunday in March and ends on the first Sunday in November. For 2025, clocks move forward on March 9, 2025, and move back on November 2, 2025. This matters for remote teams and travelers because London’s time difference with places like the UK or Europe can shift temporarily during the weeks when North America and Europe are not on the same DST schedule.
Geographically, London is in Ontario, in southwestern Canada, between the Greater Toronto Area and the Detroit-Windsor corridor. It shares the Eastern Time Zone with Toronto, Ottawa, Montreal, New York, and much of the U.S. East Coast, while neighboring Canadian zones include Central Time to the west in parts of Manitoba and Atlantic Time farther east in provinces such as Nova Scotia. For business, this means London aligns naturally with North American stock market hours, including the Toronto Stock Exchange and New York market sessions.
