Government House leader Karina Gould says the Liberal government will today vote against a key Bloc Québécois motion that the opposition party has presented as a condition of its support in future confidence votes.

Bloc Leader Yves-François Blanchet put forward a motion Tuesday calling on the government to support Bill C-319, a Bloc private member’s bill that would hike Old Age Security (OAS) payouts for seniors between the ages of 65 and 74 by 10 per cent.

For the Bloc’s pension legislation to become law, the Liberal government would have to grant a “royal recommendation” because a private member’s bill can’t force Ottawa to spend more money without cabinet approval.

The Parliamentary Budget Officer (PBO) has said the Bloc’s proposed OAS increase would cost $16 billion over the next five years — spending that would add to a national debt that is now over $1.2 trillion. The cost of financing all that debt comes to about $54 billion this year.
