QUEBEC CITY, March 28 (Reuters) - The Quebec government on Tuesday said it would cut taxes and extend a prior debt-fighting commitment, while balancing the Canadian province's books in 2017-18 for the third straight year.
Finance Minister Carlos Leitao pledged C$1 billion in Quebec's C$106 billion budget to lower taxes and said his government would invest C$2.5 billion into a fund aimed at reducing the debt.
