One destination is a tourist spot where Hawaiians have no reason to go to Vancouver in the same quantity as Canadians to Hawaii.

The other is a gateway for a country of 1 billion. I don't think they flew 343's empty on the inaugaral flight, being that people could have booked the flight months ahead (ie when it was announced). Considering the amount of Indians and Indian business interests in Surrey and Toronto, it's not the "same phenomina".

You're comparing seasonal sun-runs to year round business routes.
