Carlos Leitao has said the new Liberal government will try to relaunch the Quebec economy.
Premier Philippe Couillard has warned since taking power after winning a majority in the April election that the time has come for hard economic decisions.
The government has already brought in a hiring freeze in the public sector and is doing a complete review of its programs and services.
The Liberals have said they're aiming to meet the previous PQ government's objective of a $1.75-billion deficit in 2014-15 and a balanced budget the following year.
But a report issued Tuesday by Quebec's interim auditor general painted a grim picture of the province's public finances and cast doubts on the possibility of reaching the $1.75-billion target this year.
