Canada's Six Time Zones: Provincial Breakdown & Differences
Canada spans 5.5 hours from Newfoundland to Pacific — six time zones, some with half-hour offsets. Here's the provincial map.
Time Zones West to East
| Zone | UTC Offset | Standard | Daylight | Provinces/Territories |
|---|
| Pacific | UTC−8 | PST | PDT (UTC−7) | BC (most), Yukon (year-round UTC−7) |
| Mountain | UTC−7 | MST | MDT (UTC−6) | AB, NT, BC (east), SK (Lloydminster only) |
| Central | UTC−6 | CST | CDT (UTC−5) | SK (most, no DST), MB, NU (central) |
| Eastern | UTC−5 | EST | EDT (UTC−4) | ON, QC (most), NU (east) |
| Atlantic | UTC−4 | AST | ADT (UTC−3) | NB, NS, PE, QC (Magdalen Islands) |
| Newfoundland | UTC−3:30 | NST | NDT (UTC−2:30) | NL (Labrador southeast follows AST) |
Key Differences
- Newfoundland's half-hour: Only North American zone with 30-min offset
- Saskatchewan: Mostly CST year-round (no DST) — effectively MST in summer
- Yukon: Permanent PDT (UTC−7) since 2020 — no clock changes
- BC Peace River region: MST year-round (aligned with AB)
- Nunavut: Split across 3 zones (eastern/central/mountain)
