Toronto

They are seeking an injunction first, with a court hearing later on. Last I checked, they plan to contest the removal as a violation of the Charter of Rights given that it will lead to injuries and loss of life.

Here are the grounds from the Notice of Application from December:

1. The Ontario Government has embarked on an ill-conceived, arbitrary, and hurried legislative campaign against people who ride bikes in the City of Toronto by mandating the removal of approximately 19 kilometres of protected bike lanes in each direction on Bloor Street, Yonge Street, and University Avenue (the "Target Bike Lanes"). It has done so in full awareness of, or lacking all concern about, the increased number of injuries and deaths that will result.
2. This reckless legislative act infringes the rights of people who ride bikes (used interchangeably with "cyclists"), other road users, and/or pedestrians in the City of Toronto under s.7 of the Charter by depriving them of life and security of the person contrary to principles of fundamental justice.
3. There is no rational connection between the purported object of the law (reducing traffic congestion and gridlock) and its effect. The seriousness of the increased risk of death or serious injury to cyclists is entirely disproportionate to that ostensible objective.
