A Much-Weeded Clarification: Ontario Provides Guidance On Bill 10 As It Comes Into Force.

Ontario's Bill 10 has introduced new obligations for commercial landlords regarding illegal drug production on their premises. While the legislation initially raised concerns about scope and enforcement, recent guidance documents have clarified key aspects including what constitutes reasonable measures, when landlords may face liability, and the extent of police powers under the new regime.

Overview

When Ontario first introduced Bill 10, Protect Ontario Through Safer Streets and Stronger Communities Act, 2025, many questions remained unanswered regarding the scope of the proposed Measures Respecting Premises with Illegal Drug Activity Act, 2025 (the “Act"). In our previous articles on Bill 10, we examined those uncertainties, including who the legislation would apply to, what conduct would trigger liability, and what "reasonable measures" landlords would be expected to take.

With the Act now in force as of July 1, 2026, the Ontario government has recently issued a guidance document providing some important clarification. While a degree of uncertainty remains, the regulations and accompanying guidance significantly limit the Act's scope and offer greater direction for commercial landlords.
