Quebec is projecting a higher than expected surplus of $2.2 billion in the current fiscal year.
Information available this summer led the government to call for a surplus of $1.8 billion in the year ending next March 31.
Finance Minister Carlos Leitao's economic update today states the province will also abolish a health tax in 2017, two years earlier than scheduled.
He says his government will immediately invest the equivalent of an additional $410 million per year in the health and education sectors.
Leitao adds the Liberals also plan to increase the infrastructure fund by $400 million in the 2017-18 fiscal year, which begins next April 1.
The minister says the government will add roughly $2 billion this year to a fund dedicated to paying down the debt.
Leitao says Quebec's total debt load will decrease for the first time since the 1950s.
