The federal government is set to begin doling out $1.49 billion worth of transit funding among Ontario municipalities for track upgrades, new buses, shelters and station upgrades.

Prime Minister Justin Trudeau is scheduled to unwrap the details today in Barrie alongside Premier Kathleen Wynne.

Those details will cover some $688 million worth of projects in five Ontario cities that are lined up to be the first recipients of the dedicated transit funding.

About $500 million of the projects being announced today will be in Toronto, with Ottawa next on the list at $156 million.

Waterloo Region, Barrie and Sudbury, where the federal cabinet just wrapped up a two-day retreat, will receive about $30.6 million dollars combined for 20 projects.
