MONTREAL -- The Quebec government has announced a $9-billion plan to develop the province's maritime infrastructure.

Premier Philippe Couillard says he hopes the private sector will contribute $4 billion of the amount.

He is also hoping the plan will create 10,000 jobs within the next five years and up to 30,000 by 2030.

Some of the projects are related to tourism, fishing and transportation along the St. Lawrence River.

Part of the plan includes creating a maritime transportation logistics hub in Contrecoeur, about 60 kilometres north of Montreal, and another one in Vaudreuil-Soulanges, just west of the city.

The government's original cost estimate for the project was $7 billion.

Quebec's union of municipalities as well as the Canadian Federation of Independent Business welcomed the announcement.
