Depending where in BC would depend on transport. There really isn't much out there for "non hatchery" people.
I personally use ACE Courier out of Medicine Hat to certain places, but if they cannot do the trip in 1 day they wont do it. So I ship an afternoon and the chicks are to where they need to go by the next morning.
I am limited to a few main cities in Alberta and a couple in south east BC.
Being you live further north you could probably get them from deeper into BC as long as they have an ACE Courier depot in their city.
The other option is West Jet, a bit more costly, and your seller must be willing to box them properly and ship them, then you need to go to an airport near you to pick them up.
The third option is getting a ride with someone off the site that might be travelling between the two provinces around the time you want chicks.
Canada Post, Grey Hound are not options unless you are an inspected hatchery.
