This is among the most popular requests, but unfortunately there’s no current way to do this short of having someone on Parliament Hill do a count. I can and do report when a member doesn’t vote, but we’re unable to tell the difference between an absence and an abstention, and many days there simply aren’t any votes in the House. There’s been some noise about having Parliament release attendance records (which are currently self-reported by the parties but not made public), but at the moment those records simply don’t exist.
