There's still time to prevent the secret police bill from becoming law by either stopping it or stalling it in the Senate. You can help build pressure on the Senate, by taking a moment to contact your Senator(s) through email or social media, here: https://stopc51.ca/
So far 9 Senators have oppose the bill, 3 support it and 70 are undecided. It doesn't happen often, but there are precedents for the Senate amending bills and sending them back to the House of Commons or rejecting them outright. Public pressure can increase the possibility of this happening with C-51.
There is another day of action building momentum for May 30, including a rally on Parliament hill in Ottawa, as well as protests in London, Calgary, Toronto, Vancouver, Kitchener-Waterloo, Edmonton, Sudbury, Halifax, Regina, Barrie, Winnipeg, and Montreal.
