I don't know that they, or any Canadian schools have guarantees for job applications with any aviation companies after completing their program. I know this is often offered at some US schools, however, the Canadian industry hasn't been at that level quite yet, and be weary of "guaranteed interviews," as they may be a "go to the interview, answer the questions, get your lollypop and out you go . . . " not necessarily leading to employment.
This could be changing in the future, as Air Canada Jazz, the regional airline of Air Canada has recently started hiring a few candidates directly from a well known aviation college.
I have done some of my Instrument training at "Pro," and I can vouch for the quality of instruction provided as well as John's reputation in the industry.
Good luck though in whichever training option you will take.
