My wife's a former journalist and I considered the career path myself coming out of high school. It seems that there a lot of ways to get started - several people just have Bachelor's in Journalism or Mass Comm. Some have Master's degrees in said fields, some just have community college diplomas.
I think a lot of it has to do with geography, though. The "big 3" schools of journalism in Canada are all located in the East: Carleton in Ottawa, Ryerson in Toronto, Concordia in Montreal. Consequently, a lot of people who get their start in Journalism elsewhere in the country have community college degrees instead.
One thing to watch if considering this as a career: it's hard as hell. The competition is fierce, the jobs are scarce, you'll likely be required to move frequently and the pay is quite low until you get to the top - which may be never. I'm not saying "don't do it", but be prepared to make a lot of sacrifices to get there.
