Well
I guess the difference between Seneca and Coastal Pacific is that.
Coastal Pacific : get a B.B.A. degree (business degree) which you can find an office job easily after getting tired of flying (not that you're going to mentally, but you might fail to get Class 1 medical later in life)
Seneca: I'm not not sure what you get, as far as I know, you'll get like a science degree or something. Which it's kind of useless cause it's too general. But the good side of is government funded.
And at coastal, you get to go to a University while Seneca you go to a College. As far as I know, Airliners are now demanding higher educated pilot.
But i mean, both schools are top in Aviation in Canada. So I guess it depends who you are in order to be successful pilot.
**Correct me if I'm wrong about the Seneca program
