I don't think it is the fault of the good folks at CAaviation. I'm sure they would post any job listings that come in.
Maybe it's because there aren't any Canadian companies looking for pilots just now.
Seismic and logging jobs are down this year, Firehawk put-out all the fires in B.C., and Big Duke 6 and 407 Driver won't start heli-skiing for awhile yet.
Also very few Canadian companies ever seem to advertise. Most hiring seems to be done on the basis of dropping off a resume.
Then follow that up with incessant phone calls until the Chief Pilot hires you, and sends you 400 miles north of Fort St. Cuddlybum just to shut you up!!!!!!
