The fate of Prime Minister Justin Trudeau's minority Liberal government hangs in the balance as Parliament resumes all normal operations today for the first time in six months.

Opposition parties will give their official responses to Wednesday's speech from the throne but they've already signalled that Trudeau can't count on support from any of them to survive the eventual confidence vote and avoid plunging the country into an election in the midst of a second wave of the deadly COVID-19 pandemic.

The Conservatives were unequivocal: they will not support the throne speech.

The Bloc Quebecois was almost as categorical: Bloc MPs will not consider supporting the throne speech unless Trudeau agrees to fork over at least $28 billion more each year in unconditional transfer payments to provinces for health care, as demanded unanimously last week by premiers.

Bloc Leader Yves-Francois Blanchet is giving the government just one week to accede to that demand, in the expectation that the confidence vote on the throne speech will take place next week.

That leaves New Democrats as the Liberals' most likely dance partner but NDP Leader Jagmeet Singh has conditions of his own: legislation assuring that Canadians left jobless due to the pandemic won't have their emergency benefits cut and that Canadians who fall ill will get paid sick leave.
