Time difference between Canada and Hong Kong
12 hours to 15 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 Hong Kong" 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 | Hong Kong | 12 hours ahead | yes — also 13 hours |
| Vancouver | Hong Kong | 15 hours ahead | yes — also 16 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; Hong Kong 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.
Hong Kong. Hong Kong is UTC+8 all year and has been since 1979, when it dropped a summer-time arrangement that had run intermittently since the 1940s. It shares the offset with mainland China, which simplifies a great deal.
The same pair from the other end
This page reads the difference as Hong Kong against Canada. Hong Kong 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.
