Time difference between Canada and Japan
13 hours to 16 hours, depending on the city
Why there is no single answer
Canada spans 2 different offsets in this data — Toronto at UTC−5, Vancouver at UTC−8. One number cannot cover 2 offsets, so any single figure for "Canada to Japan" is a choice of city — declared or not. That is why two sources can both be right and still disagree, and why the useful answer is the table rather than the number.
Every combination
| From | To | Usual difference | Changes in the year |
|---|---|---|---|
| Toronto | Tokyo | 13 hours ahead | yes — also 14 hours |
| Vancouver | Tokyo | 16 hours ahead | yes — also 17 hours |
When the gap moves
2 of these 2 combinations change by an hour at some point in the year. Toronto and Vancouver go forward on the second Sunday in March and back on the first Sunday in November; Tokyo does not change its clocks. Where the two sides change on different weekends, there is a stretch of days when the difference is what neither party expects.

About these places
Toronto. Toronto keeps the same clock as New York and changes on the same dates, so the two cities are never apart. Canada follows the US daylight-saving schedule rather than the European one, which is why Toronto and London drift for the same weeks New York and London do.
Vancouver. Vancouver keeps the same clock as Los Angeles and Seattle and changes on the same dates. British Columbia legislated for permanent daylight saving in 2019, conditional on the US west coast doing the same, and is still waiting.
Tokyo. Japan is UTC+9 with no daylight saving anywhere, and has not had it since the occupation ended in 1952. The whole country runs one zone and the business day starts early, so the useful overlap with Europe is Japan's late afternoon.
The same pair from the other end
This page reads the difference as Japan against Canada. Japan to Canada states the same gap the other way round, which is the one to send someone if they are the one doing the travelling.
