Funny, I'm in Montreal too and I thought there were a lot of dangerous people on bike today, must be something in the air! The bike lane on Clark was especially crowded when I got back from work at 5:30-6.
!!!! I rode at 4:15pm to 5:00... the accidents happened on Christophe Colomb near the park and Boyer near St-Zotique (going north). Yep.. something in the air alright! Thanks for corroborating! :-)
