Colin Deacon seems to care: https://www.linkedin.com/feed/update/urn:li:activity:7519403...

Paula Simons has also been actively listening to Canadians on this subject. https://sencanada.ca/en/senators/simons-paula/

Paula Simons is almost certainly against Bill C-22, so it probably won't be of any use to contact her about rejecting it. I would focus efforts on other Senators.
