Balanced News?

Some weeks ago 8000 Pro Life marchers converged on Parliament Hill. The main stream media did not report it. I searched the internet for two days after, to find any report. There was only one that I could find on Canoe.com. But it was about a traffic cop who got hurt directing the traffic night-mare the march caused. Today however, 100 marchers show up on The Hill demanding safe injection sites for heroin addicts, and they get national attention! Like, what's with that?
