Projet Montréal is introducing another idea that would get people down to the Old Port and into the river.
At a press conference this morning, party leader Richard Bergeron says he thinks a floating pool would be an immediate hit with Montrealers.
He cites similar projects in Copenhagen, Berlin and Sydney as successful precedents.
The pool would have a mesh bottom of variable depth and would be supervised, making it safe for children.
And he says Montrealers need not worry about the quality of water in the Old Port.
"The water surrounding the island of Montreal is very good," he says. "One of the reasons in the Lachine rapids, which oxygenates the water."
He will introduce the motion at city council next month.
"I think all the members will be unanimous in their support for this idea," he says. "And if things go the way I think they will go, it should open in June 2015."
He says it would costs less than a million dollars - a fraction of the cost of building a brand new pool.
The exact location of the pool remains to be determined.
