There was the Radwanski affair, and, before that, there was Ted Weatherill. Those cases involved lavish personal expenses. They were so egregious that the result was removal from office. There was also the influence-peddling case reported on television, on CTV. A member of the Immigration and Refugee Board was filmed by the boyfriend of a woman whose case he was handling. Essentially, he wanted to exchange sexual favours for a positive decision on her case. It was all caught on video. Actually, it was not necessary to remove that person from office because he resigned. It was perfectly clear that his actions were quite unacceptable.
