One of the biggest protests was held in Montreal today, where several hundred cabbies parked their vehicles for more than an hour in an industrial park.
Cab drivers listened to speeches slamming UberX and promised even stronger actions if the provincial government fails to act.
The drivers called on the government to clarify its position on the new service, which allows users to hail a car using an application on their smartphone.
Quebec Premier Philippe Couillard suggested recently he's open to legalizing the ride-booking service while Montreal's mayor is strongly against it.
Frustrations ran high as several in the crowd of cabbies wanted to take their protest to the streets of downtown Montreal, but they were calmed by organizers.
