The Conservatives have had MPs sitting until midnight every night for several weeks to push legislation through the House of Commons.
NDP Leader Tom Mulcair, however, has been threatening to force the House to stay put until the bitter end.
Either way, Prime Minister Stephen Harper won't be in the Commons today. He's speaking at an event in Charlottetown.
Also today, the parliamentary budget officer will issue a report on how much money the federal government is expected to transfers to the provinces and territories in the current fiscal year. It will say Ottawa has shortchanged Ontario to the tune of $1.2 billion, sources say.
