About 200 Montrealers, including Projet Montréal's Richard Bergeron, took a chilly dip in the St. Lawrence this morning.

It's part of an annual event organized by Montreal Baignade, a citizens' group intent on fighting for better access to the city's waterways.

This year was the 11th annual edition of the Big Splash. Initially it was done to prove the water in the St. Lawrence was clean enough for swimming. 

Since then, however, it has become an annual rite of summer.
