Ive no idea if i should just go to regular university or go to military college

So it's time for me to decide what I want to do. I want to teach history but I also want to become an officer in the military (Canadian). I have no clue how military college is like so can someone who went to military college tell me how it's like (preferably Canadian military college). If it isn't any trouble I'd also like your opinions on my dilemma.
