Montreal is slowly catching up to Toronto. Lyft has mentioned that they are looking to add Montreal to their list of Canadian locations where they operate. They have been operating in The Greater Toronto area since the end of 2018. They also have recently launched their service in Ottawa.
Lyft mentioned that they potentially will be launching in the summer of 2019 in Montreal. Lyft thinks that the new Bill 21 in Quebec will be good for their business, even though hundreds of taxi drivers there protested against it, and some even did self imposed harm, like cutting their wrists on live TV, to get media attention.
It will certainly be a risk for Lyft to launch in Canada (remember Target?) as it will be their first international market outside the US. They are going to go slow about it and only launch in Toronto area to check out the market and work out any kinks before expanding to other major cities like Vancouver, Montreal, Calgary and Ottawa.
Can't wait for @lyft to come to Toronto. @uber service in this city is worsening daily.
