Time difference between South Korea and Canada
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 "South Korea to Canada" 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 |
|---|---|---|---|
| Seoul | Toronto | 13 hours behind | yes — also 14 hours |
| Seoul | Vancouver | 16 hours behind | yes — also 17 hours |
When the gap moves
2 of these 2 combinations change by an hour at some point in the year. Seoul does not change its clocks; Toronto and Vancouver go forward on the second Sunday in March and back on the first Sunday in November. 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
Seoul. South Korea is UTC+9, the same as Japan, and briefly used UTC+8:30 in 1954 and again in 1961. North Korea moved to UTC+8:30 in 2015 and back to UTC+9 in 2018 to match the South.
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.
The same pair from the other end
