About Longueuil Time Zone
Longueuil uses the America/Toronto IANA time zone database identifier, the same zone used across much of southern Ontario and Québec, including Montréal and Toronto. Its standard time is UTC-5, known as Eastern Standard Time (EST), and during daylight saving time it shifts to UTC-4, known as Eastern Daylight Time (EDT). Because Longueuil sits directly across the St. Lawrence River from Montréal in Québec, its business hours align closely with the wider Montréal metropolitan economy.
Longueuil observes daylight saving time, with clocks moving forward on the second Sunday in March and moving back on the first Sunday in November. For 2026, this means the switch to daylight time occurs on March 8, 2026, and the return to standard time occurs on November 1, 2026. This seasonal change matters for scheduling with Europe, Asia, and Australia because the time gap can temporarily widen or narrow during weeks when other countries change clocks on different dates or do not observe DST at all.
Within Canada, Longueuil’s time matches Montréal, Ottawa, Toronto, and New York’s regional business clock, but differs from nearby zones such as Atlantic Time (UTC-4 standard) in parts of eastern Canada and Central Time (UTC-6 standard) farther west. That means a 9:00 AM start in Longueuil is 10:00 AM in Halifax during standard time and 8:00 AM in Winnipeg during standard time, which is important for national customer support coverage, transportation planning, and multi-province operations.
Longueuil City Details
Longueuil is a major city in Québec, Canada, with a population of 229,330, making it one of the significant urban centers in the Greater Montréal area. It is located at 45.53121° N, -73.51806° W, on the south shore of the St. Lawrence River, directly opposite Montréal, which gives it strong commuter, transit, and commercial links to one of Canada’s largest economic hubs.
The local currency in Longueuil is the Canadian dollar (CAD), which is the standard currency for retail purchases, salaries, contracts, and travel expenses throughout Canada. The country dialing code is +1, so international callers dialing Longueuil use Canada’s North American numbering format, the same broader telephone system used by both Canada and the United States.
Because Longueuil shares the Montréal metropolitan labor market, its local time is particularly relevant for industries such as aerospace, public administration, education, healthcare, transport, software, and professional services. Travelers using Montréal–Trudeau International Airport or coordinating rail, road, and regional business appointments often need precise Longueuil time conversions to avoid confusion during DST transitions and cross-border scheduling.

Longueuil is commonly 16 hours behind Sydney during Longueuil standard time and 14 hours behind Sydney when Sydney is on standard time while Longueuil is on daylight time; the exact gap varies seasonally because Australia’s DST calendar differs by state and by date. As a working example, when it is 9:00 AM in Longueuil, it is often 1:00 AM the next day in Sydney or 11:00 PM / 12:00 AM next day depending on the month, so real-time collaboration usually requires one side to meet very early or very late.
