Hello, starting next week and going on for the next three weeks Terrebonne avenue in Montreal is going from a two lane road to a single lane road with bike paths. It is diverging from Cavendish blvd into a single lane going to the east and a single lane going west. Here is the link to the work being carried out on the City of Montreal website. Thank you.
I live in NDG and it is already set. 
Although the city has not announced the exact day each section will come into effect and any possible complete closures during the conversion. So Waze might be off a few days.
