The Score doesn't have a contract to carry Canada West games. Shaw owns exclusive regular season rights to Canada West, The Score has OUA, RDS has Quebec and Eastlink has AUS.
I find it funny that people complain about the lack of Canadian content on Canadian stations, then others turn around and complain about "Ontario garbage" featuring two teams full of Canadians being on over a US college game featuring virtuallly no Canadians. I guess you can't please everybody. I actually like the fact that The Score airs CIS games on Saturday afternoon when they could easily take the cheap way out and buy the 12:00pm package of ESPN games. Its not often that a Canadian network chooses amatuer Canadian sport over a simulcast of a US league/event.
