Class Action
Shelter Bed
Lewis Litigation, partnering with Steiber Berlach LLP and the Black Legal Action Centre, has commenced a proposed class action against the City of Toronto for their decision to exclude refugee claimants from accessing the City’s base shelter beds between 2022 and 2023. If you are a refugee claimant and were denied access to a shelter bed in the City of Toronto, we would like to hear from you.
