YYZ-bound flights are the slower direction by about 60 minutes in our estimate: the route runs mostly east–west through latitudes where the prevailing westerly winds at cruise height are strong, so heading east rides a tailwind and heading west fights a headwind. How we estimate it.

Time zones and jet lag

YYZAmerica/Toronto — UTC−4 now; UTC−5 standard time, UTC−4 during daylight saving time
LHREurope/London — UTC+0 now; UTC+0 standard time, UTC+1 during daylight saving time
DifferenceLondon is 4 hours ahead of Toronto today.

Jet lag, flying YYZ → LHR. Your body clock has to move 4 hours earlier, like an eastward trip. A common rule of thumb is that the body clock adjusts by roughly one time zone a day, so expect up to about 4 days to fully adjust. Shifting earlier (as here) is usually the harder direction; morning daylight at the destination helps. Flying the other way, the shift is reversed.
