Time difference between Portugal and Canada
5 hours to 8 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 "Portugal 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 |
|---|---|---|---|
| Lisbon | Toronto | 5 hours behind | yes — also 4 hours |
| Lisbon | Vancouver | 8 hours behind | yes — also 7 hours |
When the gap moves
2 of these 2 combinations change by an hour at some point in the year. Lisbon goes forward on the last Sunday in March and back on the last Sunday in October; 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
Lisbon. Portugal keeps UTC, an hour behind neighbouring Spain despite sitting further west than most of it. The country tried Central European Time from 1992 to 1996 and abandoned it after schoolchildren were leaving home in the dark, which is the clearest natural experiment anyone has run on the question.
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 Portugal. Canada to Portugal states the same gap the other way round, which is the one to send someone if they are the one doing the travelling.
