Federal Transport Minister Marc Garneau has announced a review of Canada Port Authorities.

The government says the current port system has served the country well over the past 20 years, however a lot has changed and will continue to change heading into the future.

The 18 Canada Port Authorities were created in 1998 to operate on a commercial basis at arm's-length from the federal government.

"Ports are a critical part of Canada's transportation network and trade corridors, and need to remain innovative and competitive in today's dynamic environment," said Garneau. "I invite marine stakeholders and Canadians to provide input that will help shape the future of Canada's port system, so that it continues to support sustainable and inclusive growth."

The review will gather feedback through a series of round tables and meetings with various stakeholders including Indigenous peoples, Canada Port Authorities, provincial governments, municipalities, broader domestic and international marine sector stakeholders, and Canadians.

Findings of the review are expected in 2019.
