Ontario Court Dismisses Developer SLAPP Lawsuit

The developer SLAPP lawsuit ended this week when an Ontario Superior Court judge threw out Sheridan Retail’s defamation and trespass claims against engineering student Pierre Roy. Justice Renu Mandhane ruled that the case aimed to muzzle his public criticism on environmental and housing issues at community meetings.

Roy had voiced concerns about sustainability and affordability during consultations on Sheridan Mall’s proposed 15-storey residential towers. He also photographed active construction zones and flagged safety violations to city officials. Consequently, the City of Mississauga investigated and confirmed that the developer lacked proper building permits.

On the same day the city rejected Dunpar Homes’ proposal in December 2023, Sheridan Retail sued Roy for $300,000. The company described his actions as defamatory and trespassing. However, Mandhane found that Sheridan Retail simply wanted to intimidate a 24-year-old student into silence ahead of council’s vote.

Furthermore, the judge awarded Roy $25,000 in damages and ordered Sheridan Retail to cover his legal fees. She condemned the developer’s “heavy-handed litigation tactics” and noted that its true aim was to chill his continued public participation.

Ontario’s anti-SLAPP legislation protected Roy by allowing quick dismissal of lawsuits that stifle free expression in matters of public interest. Sheridan Retail had conceded Roy’s right to speak but asked the court to let trespass claims proceed. Justice Mandhane rejected that request, calling it another attempt to litigate him into silence.

Despite the setback, the developer plans to appeal to the Ontario Court of Appeal. In its statement, Sheridan Retail maintains it sought to safeguard public safety on an active work site and protect its property rights. Meanwhile, the company’s residential plans have advanced: the Ontario Land Tribunal approved two 15-storey towers with 631 units this January.

Roy emphasized that he never opposed redevelopment outright. “I support building here,” he said, “but I want the project to serve our community’s best interests.” He added that the court’s decision reinforces citizens’ right to participate in planning processes.

This ruling sets a significant precedent for public participation in Ontario. By dismissing the developer SLAPP lawsuit, the court affirmed that community members can raise concerns without fear of crippling legal action. Ultimately, the decision underscores the value of free speech in local development debates.
