Expanding the Toronto island airport is officially off the table, according to the new Liberal Transport Minister.

“I confirm that (the Government of Canada’s) position is same as (Liberal Party) commitment: we will not reopen tripartite agreement for YTZ,” Marc Garneau tweeted Thursday.

The announcement came just hours after Garneau told reporters that he was still reviewing the file.

During the campaign that brought them to power, the Liberals vowed to block a proposed expansion at Billy Bishop airport that would have extended the runway to accommodate jets.

Expansion at the airport requires a commitment from the federal government, the city, and the Toronto Port Authority to reopen the tripartite agreement that governs the airport.

Advocacy group NoJetsTO has declared victory Friday.

“Today Toronto residents woke up to the good news that the threat of jets on our waterfront is removed,” Norman Di Pasquale, chair of NoJetsTO, said in a news release.

“It’s a pivotal moment for the future of our waterfront that is the result of 2.5 years of citizen-led action,” he added.

The group is calling on city council and the Port Authority to halt the ongoing expansion study.

Despite campaign promises from the Liberals to effectively halt the expansion, Porter Airlines urged the Trudeau government to “consider the wishes of the people of Toronto.”

The airline was hoping for an expansion of the airport runways to accommodate CSeries jets, which would allow Porter to offer service to places further afield.

Last year, Toronto council delayed a decision on the jets issue, asking airport operator PortsToronto to do an environmental assessment, airport master plan and runway design study. The reports were expected in early 2016.
