As Toronto considers whether to bid for the 2024 Summer Olympics, the only other North American city to openly express interest has withdrawn from the race.

Boston has cut ties with the U.S. Olympic Committee – on the heels of low support for the prospect of a bid for the ’24 Summer Games – and the activities of an active opposition group.

Meanwhile, there’s talk of a third Toronto Olympic bid – following the city’s successful Pan Am Games. But Toronto Mayor John Tory says he wants to let the dust settle before making a decision – and officials will conduct a “careful analysis” to determine whether a bid is in the city’s best interest.

The head of the Canadian Olympic Committee wants to forge ahead with the pitch, and the president of the Canadian Paralympic Committee has also thrown his support behind the idea.

Cities who want to host the 2024 Games have until September 15th to register their interest with the International Olympic Committee.
