The short answer: Most of Canada uses the exact same time zone and daylight-saving dates as its neighbouring US region: Toronto and New York are both Eastern, Vancouver and Los Angeles are both Pacific, a 0-hour difference. There are two real exceptions: Saskatchewan doesn't observe daylight saving, matching Central Time in winter and Mountain Time in summer, and Newfoundland runs 30 minutes ahead of Atlantic Time.
USA-Canada is an unusual pair to write about, because for most people crossing this border, there simply isn't a time-zone problem to solve. The interesting cases are the exceptions, and the very common situation of a US company hiring across Canada's own internal zones.
Same zone, same rules
Canada's four mainland time zones, Pacific, Mountain, Central and Eastern, line up exactly with the US zones of the same name, and both countries change their clocks on the same dates. That means:
| Canadian region | Matches US zone | Difference |
|---|---|---|
| Toronto, Montreal, Ottawa | Eastern (ET) | 0 hours |
| Winnipeg | Central (CT) | 0 hours |
| Calgary, Edmonton | Mountain (MT) | 0 hours |
| Vancouver | Pacific (PT) | 0 hours |
The Saskatchewan exception
Saskatchewan is Canada's version of Arizona: it stays on standard time all year and never observes daylight saving. Since its neighbours do shift, Saskatchewan effectively matches Central Time in winter and Mountain Time in summer, the same "which zone am I actually in today" pattern Arizona has with Denver and Los Angeles.
The Newfoundland exception
Newfoundland Time sits 30 minutes ahead of Atlantic Time, one of the small handful of half-hour offsets anywhere in the world. It's a historical artefact rather than a daylight-saving quirk, see our guide to why some time zones are 30 or 45 minutes off for the wider pattern.
When there is a real gap
The genuine scheduling question isn't "US vs Canada," it's "which zone within each country." A New York company hiring a remote developer in Vancouver has exactly the same 3-hour gap it would have hiring someone in Los Angeles, the border itself changes nothing. Treat a cross-border hire like any domestic cross-zone hire, and check the specific cities involved rather than assuming "Canada" means one offset.
Why do so many US companies hire remotely in Canada?
Shared language, closely aligned business hours, and a similar time zone map to the US make Canada one of the easiest cross-border markets to hire in, especially compared to hiring across an ocean. Because most of Canada sits in the exact same zone as its nearest US neighbour, a Toronto or Vancouver hire often behaves, scheduling-wise, exactly like hiring someone in another US city, which is precisely why it's easy to overlook the two real exceptions above.
That near-perfect overlap is also why Canadian hires rarely get flagged as a scheduling risk during onboarding, when in practice the risk isn't the country, it's whichever specific province the hire happens to be in. A quick check against the table above takes a minute and avoids a surprising number of avoidable "why did the invite send at the wrong time" support questions later.
"Canada" spans six time zones, from Newfoundland to the Pacific. Before assuming there's no gap, confirm the specific city, especially if Saskatchewan or Newfoundland is involved.
Keep every city straight automatically
With this many near-matches and two genuine exceptions, it's easy to assume "no time difference" when there actually is one. Atlas tracks each teammate's real city, including Saskatchewan and Newfoundland's quirks, so the overlap shown is always correct.
