Most Canadians assume we have the right to speak out when a controversial development is proposed in our neighbourhoods.
We can attend public meetings, email city hall, photograph construction activity, and raise concerns about planning, safety or the environment. These activities are fundamental to our democratic rights.
But what happens if a developer responds not with answers, but with a lawsuit seeking hundreds of thousands of dollars?
That question was at the heart of a significant May 2026 decision of the Ontario Court of Appeal.
In 2022, Sheridan Retail Inc., started to redevelop Sheridan Mall in Mississauga. The project included renovation of existing storefronts and a proposal to build two 15-storey condominiums.
Pierre Roy was an engineering student and member of the local residents’ association. He publicly opposed aspects of the development and raised concerns about sustainability, affordable housing, and allegedly unsafe and unlawful construction practices.
He attended meetings, communicated with city officials, photographed aspects of the construction, and raised concerns with the City about planning, public safety, and compliance with municipal bylaws and the building code.
The developer sued Roy, claiming $300,000 for defamation, trespass, inducing breach of contract, and intentional interference with economic relations, alleging he had crossed the line between legitimate criticism and unlawful conduct.
In response, Roy brought a court motion seeking to dismiss the lawsuit under Ontario’s anti-SLAPP legislation. SLAPP stands for Strategic Lawsuit Against Public Participation. Lawsuits like the Sheridan claim are often intended to discourage public criticism by forcing defendants to spend enormous amounts of money and time defending themselves.
In 2015 Ontario enacted section 137.1 of the Courts of Justice Act. It allows judges to dismiss lawsuits at an early stage if they arise from expression on a matter of public interest, unless the plaintiff can show the case has substantial merit, the defendant has no valid defence, and the public interest in continuing the lawsuit outweighs the public interest in protecting freedom of expression.
At the hearing of Roy’s motion in May 2025 Justice Renu Mandhane concluded Roy’s comments dealt with matters of undeniable public interest: municipal planning, redevelopment, public safety and building compliance.
Justice Mandhane dismissed Sheridan’s action, awarded Roy $25,000 in damages under the anti-SLAPP legislation, and granted him legal costs of $156,394.57.
The judge wrote that Sheridan’s action “was a quintessential gag suit aimed at curtailing public expression.”
Sheridan appealed, and in May the Ontario Court of Appeal largely upheld the decision. It emphasized that courts must look beyond the legal labels attached to a lawsuit and determine its true purpose.
The real question is whether a lawsuit is fundamentally aimed at discouraging protected public participation. In Roy’s case, the answer remained yes.
The Court of Appeal confirmed that the discussion of municipal planning, construction practices, public safety and environmental concerns lies at the heart of democratic debate. Residents should not face financial ruin simply because they express concerns or communicate with public officials.
The appeal court affirmed the dismissal of the Sheridan lawsuit and the $25,000 damages award, but reduced the costs in the lower court to $75,000. Roy was also awarded another $20,000 in costs for the appeal. His total award was $120,000.
The ruling offers important lessons for both developers and the public.
For developers, litigation should not become a substitute for public relations. Major projects inevitably attract questions about density, traffic, environmental impacts, infrastructure and safety.
Those concerns are often sincerely held, even if they ultimately prove to be unfounded. Suing critics may generate far more negative publicity than the criticism itself.
For residents, however, the decision is not a licence to say anything without consequence. Ontario’s anti-SLAPP legislation protects responsible participation in matters of public interest.
It does not shield knowingly false statements, malicious accusations or conduct that falls outside legitimate public debate. Citizens remain responsible for ensuring factual allegations have a reasonable basis.
As redevelopment accelerates across Ontario, conflicts between developers and neighbourhood residents are becoming more common. The public consultation process can function properly only if citizens feel free to participate without fear of financially crippling litigation.
