Should Trudeau be able to charge speaking fees?

My column this week on Loonie Politics revisits the issue of MPs and senators charging speaking fees for professional engagements outside of their parliamentary duties, given the way that the issue of Trudeau's fees blew up again at the end of last week. It's a good opportunity to remind people of the actual role of MPs - holding government to account and scrutinizing the estimates - and brings in the expense issue of Senator Pamela Wallin as an example of where the arguments against fees will wind up.
