Maclean’s is your home for the daily political theatre that is Question Period, when opposition and government MPs trade barbs and take names for 45 minutes every day. Today, QP runs from 2:15 p.m. until just past 3. We tell you who to watch, we stream it live, and we liveblog all the action. The whole thing only matters if you participate. Read our morning tease to catch up on the issues of the day, and then chime in on Twitter with #QP.

HOT SEAT Cast your mind back to the spring, when Tom Mulcair and Stephen Harper went after each other on the Senate expenses scandal. Today might well herald a return to those famously prosecutorial exchanges, now that Sen. Mike Duffy’s lawyer has invaded the news cycle and launched new questions about who knew what in the Prime Minister’s Office about Duffy’s problematic expenses. Meanwhile, Duffy and his Senate colleagues, Sen. Pamela Wallin and Sen. Patrick Brazeau, face possible suspension from the Red Chamber. Today requires several heated seats.
