  • Successfully defended Montréal Gateways Terminals (“MGT”) before the Supreme Court of Canada in Singh et al. v. Montréal Gateways Terminals et al.  In the case, the plaintiffs, who were of the Sikh religion, alleged that a mandatory health-and-safety-related policy implemented by MGT, requiring all individuals entering its terminal in the Port of Montréal to wear a protective helmet, infringed their rights of freedom of religion and equality. The Superior Court, Court of Appeal and, ultimately, the Supreme Court of Canada confirmed that MGT was entitled to require that persons of the Sikh religion wear hard hats over their turbans despite their religious beliefs prohibiting them from doing so.
