If he is looking to go in to policing, then I would recommend Guelph-Humber. Their degree+diploma curriculum offers both a theoretical and practical experience, and that's what most employers are looking for. I myself want to go to Guelph-Humber in the coming Fall.
Also, in the third and fourth year, he'll partake in two different placements. With the 100 hours of experience each placement supplies, it'd be a great way to have experience, and that would be an excellent advantage against other applicants.
I'm not sure about Ottawa University because I have no insight on their program, but I'm sure it is great as well.
