Ontario Liberals say they will reduce transit fares to one dollar per trip across the province until 2024 if elected in June.

Officials said the plan would apply to all municipal lines as well as Go Transit and Ontario Northland service. The cost of a single trip will be reduced to $1 while monthly passes will be about $40.

The party said the dollar fare will be in effect until January 2024. Liberal leader Steven Del Duca said in a statement, "Our plan will provide families with immediate relief within the first 100 days of being elected, by lowering the transit fare.

Passengers who take GO from Whitby to Toronto will save over $300 a month." The party says the plan will cost about $710 million in 2022-23 and about $1.1 billion in 2023-24. According to the Grits, the province will spend money to make up for lost revenue, ensuring municipalities are not affected.

Del Duca also pledged to invest an additional $375 million in annual transit operating funding to support more bus routes, extended service hours, and "more intercity connections." It is unclear how the government will pay for this promise—Del Duca said his party will release its full cost platform in the coming days.

It is also unclear whether transit fares will increase after 2024. Speaking to reporters at the Metro Conference Centre in Toronto on Monday morning, Del Duca would not confirm whether transit users will see a fare increase after this deadline.
