Coderre made the announcement regarding the summer gathering on Monday during a trip to France, where he met with his Paris counterpart, Anne Hidalgo, and French President Francois Hollande.
He said his goal is to unite the world's mayors in order to discuss how to find a balance between "openness and vigilance."
"I'm thinking big," Coderre said. "What can we do together to cover all the angles?"
Montreal is scheduled to host the International Economic Forum of the Americas in June and Coderre said he'll take advantage of that event to bring together mayors from every continent.
In particular, Coderre said he's looking to invite the mayors of Brussels, Berlin, Los Angeles, Barcelona, Chicago and also Boston, which is slowly recovering from the 2013 bombing of its international marathon.
Hidalgo said she accepted Coderre's offer to visit Montreal next summer.
"Our cities are refugee cities," she said. "They are inclusive, very creative, in which security needs to be assured. Security is non-negotiable. We are generous but not naive."
Coderre's visit to Paris is his second less than a year.
He met with Hollande for half-an-hour on Monday.
On Tuesday, Coderre is scheduled to lay flowers at the kosher grocery store that became the scene of a fatal hostage standoff in January, two days after the mass shootings at the Charlie Hebdo magazine offices.Suggest a correction
