Time difference between Thailand and Canada
11 hours to 14 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 "Thailand 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 |
|---|---|---|---|
| Bangkok | Toronto | 11 hours behind | yes — also 12 hours |
| Bangkok | Vancouver | 14 hours behind | yes — also 15 hours |
When the gap moves
2 of these 2 combinations change by an hour at some point in the year. Bangkok 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
Bangkok. Thailand is UTC+7 and fixed, and it counts years by the Buddhist Era, 543 ahead of the Gregorian one. A date in a Thai document may be 2569 for a year written 2026 elsewhere.
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
This page reads the difference as Canada against Thailand. Canada to Thailand states the same gap the other way round, which is the one to send someone if they are the one doing the travelling.
