First, watch this interview the day before the event on May 11th, 2022 with the actual organizer of the March for Life, Jack Fonseca. Then, watch a video of the start of the march from the hill around parts of downtown.
Then check online for what the government controlled media has to say. This would be mostly CBC, CTV, Global News, and CFRA-AM, a formerly conservative talk radio station. Please feel free to leave links in the comments with what you find, or even if you find nothing. Remember, Trudeau was for his first few years in office, as hostile to people who opposed abortion as he is now to people who think you have a right to informed consent for medical treatment. In fact, he attempted to pass a law of sorts, that no company connected to aspects of the government could hire anyone for a student program unless they signed a document with the politically correct views on abortion.
