I'm back in Toronto. Had a much easier trip home than the one out, though I didn't wind up sleeping at all this time. Pleasant older lady sat with me on the last leg (Vancouver to Toronto) and made the time pass quickly.

Total travel time was ~27 hours door-to-door, which made for a long day, but I seem to have survived reasonably well. Vancouver airport apparently only provides plugs and free wifi in the international departures lounge, so no work done there this time. Didn't find a power socket in Seoul either.
