Alberta ag-gag law
Law & Regulation
In Effect
November 29, 2019
Summary
On 29 November 2019, the Legislative Assembly of Alberta passed Bill 27 — Trespass Statutes (Protecting Law-Abiding Property Owners) Amendment Act, 2019 — at third reading. Introduced by the Minister of Justice and Solicitor General on 19 November 2019, the Act amends five existing Alberta statutes: the Petty Trespass Act, Trespass to Premises Act, Occupiers’ Liability Act, Limitations Act, and Provincial Offences Procedure Act. The core amendments relevant to animal agriculture are: (1) a new “no-notice” trespass prohibition in the Petty Trespass Act (s.2.2), making entry without permission an offence on enclosed land used for raising and maintaining animals (including birds and fish), producing crops, or keeping bees — without requiring signage or prior oral notice; (2) a provision deeming entry obtained by false pretences to be entry without permission, thereby classifying undercover investigators or employees who obtain access under misrepresented purposes as trespassers under both the Petty Trespass Act and the Trespass to Premises Act; (3) substantially increased maximum penalties — up to CAD 10,000 and/or 6 months’ imprisonment for a first offence by individuals, up to CAD 25,000 and/or 6 months’ imprisonment for subsequent offences, and up to CAD 200,000 for corporations; (4) corporate and officer/director liability where organisations aid, counsel, or direct trespass; and (5) revised Occupiers’ Liability Act provisions narrowing circumstances in which occupiers owe a duty of care to “criminal trespassers,” defined as trespassers on land where the occupier has reasonable grounds to believe a Criminal Code offence is being or about to be committed. Alberta Justice Minister Doug Schweitzer described the law as targeting “animal rights radicals” who protest on farms. Civil society organisations including Animal Justice describe Bill 27 as Canada’s first ag-gag law. The law has no documented constitutional challenges specific to its provisions; a related Critical Infrastructure Defence Act (Bill 1, 2020) faced challenges, and the Supreme Court of Canada denied leave to appeal a challenge to that Act in 2022.
Background Context
Before Bill 27, Alberta’s Petty Trespass Act and Trespass to Premises Act had maximum fines of approximately CAD 2,000 for a first offence and CAD 5,000 for subsequent offences — substantially lower than the 2019 amendments. The bill was introduced following an occupation of a free-range turkey farm in southern Alberta by dozens of activists, cited in secondary sources as the precipitating political event. A parallel trend of ag-gag legislation was developing across Canadian provinces; Animal Justice documents that ag-gag laws were subsequently passed in Ontario (2020), Manitoba, and Prince Edward Island. At the federal level, similar debates occurred around proposed amendments to the Health of Animals Act (Bill C-205) addressing biosecurity and facility access. The Ontario ag-gag law (Security from Trespass and Protecting Food Safety Act, 2020), its partial constitutional invalidation (2024), and its appellate reinstatement (2026) are documented in separate Development records. Canada’s first G20 shark fin trade ban (Bill C-68, 2019) was enacted in the same year as Bill 27.

Bill 27 received third reading on 29 November 2019 and Royal Assent in 2019 (exact assent date not reproduced in the bill PDF; see ECN). The law’s key provisions take effect upon coming into force: the no-notice trespass prohibition on land used for raising animals, the false-pretence deemed-trespass rule, and the increased penalty structure. Some civil liability and limitation provisions include retroactivity to 1 January 2018. Prior maximum fines for trespass (CAD 2,000–5,000) were replaced by substantially higher thresholds (CAD 10,000–25,000 for individuals, CAD 200,000 for corporations). Corporate and officer/director liability provisions create organisational accountability for directing or facilitating trespass on agricultural land. No specific charges, convictions, or prosecutions under Bill 27’s agricultural provisions are documented in sources consulted. The Critical Infrastructure Defence Act (Bill 1, 2020), a related Alberta statute covering essential infrastructure including certain agricultural operations, subsequently faced constitutional challenge; the Supreme Court of Canada denied leave to appeal in 2022. No comparable concluded constitutional challenge to Bill 27 itself is documented in sources consulted.
Anticipated Effects
If implemented as written and enforced, the classification of false-pretence entry as trespass increases legal exposure for undercover investigators and employees who obtain access to agricultural facilities under misrepresented purposes, which would be expected to increase the legal risk of conducting such investigations in Alberta.
If the higher penalty structure — up to CAD 200,000 for corporations that aid, counsel, or direct trespass — is applied against organisations supporting undercover investigations, this would increase the financial deterrence against organised investigative activity at Alberta agricultural operations.
If the no-notice prohibition on land used for raising animals is enforced consistently, entry onto such land without permission would constitute a trespass offence absent any signage or prior notice, potentially facilitating enforcement against individuals present at farm boundaries without explicit property markings.
Whether Bill 27 has produced any measurable change in the frequency or character of undercover investigations, farm protests, or documented welfare exposures in Alberta is not established in available sources.
Significance Rationale
Assigned Neutral / Administrative (impact direction) because the law modifies the legal environment governing access to agricultural facilities and liability for trespass, without directly mandating changes in animal production volumes, facility numbers, or the scale of animal exploitation in Alberta. The system of animal agriculture continues; the law alters the legal conditions for its oversight and the consequences of unauthorised access.
Assigned Alters Legal Basis (impact type) because the primary mechanism is statutory redefinition — false-pretence entry is deemed to be trespass; “no-notice” trespass prohibitions are extended to land used for raising animals and keeping bees; penalties are substantially increased; and occupiers’ civil liability to “criminal trespassers” is narrowed. These are legal basis changes, not modifications of conditions within a continuing production system.
Assigned Moderate significance because the law affects all agricultural land and premises used for raising animals in Alberta — sector-wide within one province — altering the legal conditions for investigative access, protest, and associated liability. The law does not directly alter production quotas, licensing, trade conditions, or animal numbers; its material effect is on how the legal environment governing agricultural facility access operates within Alberta.
Impact direction is Neutral / Administrative; the trajectory sentence is not applicable.
Within The System
Key Actors
The Legislative Assembly of Alberta enacted Bill 27; the bill was introduced by the Minister of Justice and Solicitor General. Alberta Justice Minister Doug Schweitzer publicly supported the legislation. Alberta’s policing and prosecutorial authorities enforce the amended trespass provisions. Animal Justice documented the law as Canada’s first ag-gag statute and anticipates Charter challenge. The trigger for introduction was an occupation of a turkey farm in southern Alberta by animal activists.
