Rodenticides Registered in Canada
Which rodenticides are registered in Canada?
Health Canada's PMRA register currently lists 182 product registrations whose product type includes "rodenticide", built on 19 active ingredients. All of them hold Full Registration except one strychnine product, which holds an Emergency Registration. The anticoagulant baits make up most of the list.

| Strychnine | 1 (Emergency Registration, Restricted class) | 2% Liquid Strychnine Concentrate (28751) [20] |
How the 182 break down:
- By marketing class: 80 Commercial, 50 Domestic, 13 Restricted, 26 technical actives and 13 manufacturing concentrates.
- By product type: 167 are classed as rodenticide only. The other 15 are multi-purpose products, mainly fumigants such as the phosphides, methyl bromide, phosphine and carbon dioxide, also classed as insecticide or animal toxicant.
Products left out of the count:
- Degesch Phostoxin Round Tablets Rodenticide (16351): an aluminum phosphide product classed only as "animal toxicant". It is labelled for Richardson's ground squirrel and woodchucks [21].
- Rodent repellents: products such as those based on denatonium benzoate are classed as "animal repellent", not rodenticide.
Many registrations, for example Hawk Rodenticide (bromadiolone), show an expiry date of 2026-12-31 [22].
The panel document "Current PMRA-registered rodenticide products" lists all 182 registrations. For each it gives the registrant, active ingredient, status, marketing class and expiry date, with a citation per row.
Approach: I searched Health Canada's Pesticide Product Information Database (the PMRA product register) for current registrations, filtered on product type, and also checked records labelled for rats, mice, gophers, voles and ground squirrels that are classed under other product types.
Which rat poisons can homeowners use?
In Canada, homeowners can use the 25 rat-labelled products in the Domestic class (the consumer class) of Health Canada's PMRA register. They contain diphacinone, bromethalin, chlorophacinone, corn-cob cellulose, canola oil or sulphur. None of the 50 current Domestic rodenticides contains brodifacoum, bromadiolone, difethialone, zinc phosphide or strychnine. Those actives appear only in Commercial, Restricted or technical registrations.

Other Domestic rodenticides:
- Pests not stated: BASF's TC 411, TC 412 and TC 413 Rodent Baits (cholecalciferol, registered 2026-06-25) list no pests or sites in the register, so I can't say whether they are labelled for rats [44][45][13].
- Mice only: the other 22 Domestic products are labelled for mice only and are not for rats. Examples are Tomcat Mouse Killer (30757) [46] and the Wilson Mouse Out warfarin bait station (30854) [47].
Approach: I searched Health Canada's Pesticide Product Information Database (the PMRA register) for current Domestic-class rodenticides and read the pests and sites listed on each record. The register summarises pests and use sites but not the full label directions, so it does not show conditions such as bait-station requirements.
What are the bait station and label requirements?
For homeowner (Domestic-class) rodenticides in Canada, Health Canada's rules are that bait must be a block or solid, the product must be sold packaged with a bait station, and it must always be used in that station. The station must lock, keep the bait from being shaken loose, and carry the key label information. Second-generation anticoagulants (brodifacoum, bromadiolone, difethialone) are prohibited in Domestic products.
Domestic-class product requirements (Health Canada Q&A, Q7, page modified 2017-05-04, source):
- "Block or solid formulations are the only types allowed. Bait must be in a form that is reasonably expected to remain in bait station, except for bait removed, and crumbs created, by target rodents."
- Loose baits (meal, treated whole grain, pellets, liquid) are prohibited. So are concentrates meant to be diluted into bait (solution, emulsifiable concentrate, dust, powder).
- "Domestic class products must always be used in bait stations."
- "Products must be sold packaged with a bait station which must meet the bait station requirements."
- Manufacturers had until 31 December 2012 to have the new labelling in place.
Bait-station requirements (Health Canada, published 2024-07-26, source). This page is written for Commercial-class products. The Domestic rule above refers to "the bait station requirements", which I take to mean these.
- Every station must:
- have an internal structure that stops the bait being shaken loose;
- have an access panel that closes securely and locks (for example with screws or a padlock).
- The station itself must show: the product name, active ingredient, guarantee, registration number, "WARNING POISON" and the skull-and-crossbones symbol.
- Tiers, each building on the one below:
| Tier | Criteria | Required placement |
|---|---|---|
| Tier 3 | High-strength material (e.g. metal or injection-moulded plastic) that children cannot destroy; entrance designed so children cannot reach the bait | Indoors, where children can reach it but pets or livestock cannot |
| Tier 2 | Tier 3, plus resistant to destruction by non-target animals; entrance designed so those animals cannot reach the bait | Indoors, where children and pets or livestock can reach it |
| Tier 1 | Tier 2, plus resistant to destruction or weakening by bad weather (snow, rain, temperature and humidity extremes, direct sun) | Outdoors above ground, where children, pets and non-target wildlife can reach it |
- Slotted-floor "holes" and burrows count as below ground and out of children's reach, so no station is needed there.
How this shows up in the register:
- Placement on labels: several Domestic rat products are labelled for "indoors; outdoors within 15 m of buildings" (shown in the previous answer). Health Canada's agricultural-settings page sets the same 15 m limit for Commercial products. It also allows up to 100 m along fence lines in a secured, tamper-resistant station, effective 1 January 2013 (page modified 2023-03-27, source).
- Station testing: the file for the Domestic Tomcat Rockscape station (34112) lists the data filed for the station. This includes bait-security tests on the Protecta EVO Landscape station, a dog-testing video, weather-resistance statements and adult open/reclose testing [48].
Origin and what's coming:
- These measures come from PMRA's REV2010-17, Risk Mitigation Measures for Eight Rodenticides (revised), 2010 [49]. The register holds only its index entry, not the text.
- The Q&A does not name the eight actives. Some current Domestic products are pellets (the corn-cob cellulose products), so the formulation ban does not appear to cover every active. I could not confirm its exact scope without the REV2010-17 text.
- PMRA's 2026–2031 work plan (REV2026-03, 30 June 2026) schedules a proposed re-evaluation decision for consultation by March 2027. It covers a rodenticide cluster: brodifacoum, bromadiolone, bromethalin, chlorophacinone, diphacinone, warfarin, zinc phosphide and difethialone (source).
For users: Health Canada's rats-and-mice page says poisoned baits "must be used with a tamper-proof bait station in areas accessible to children and pets." It also says to "read the product label and follow the label directions and safety precautions closely." Using a pesticide in a way that goes against its label "is a violation of the Pest Control Products Act" (source; source).
Approach: I searched the PMRA product register, its decisions, consultation and policy-notice indexes, then read Health Canada's official rodenticide pages. The register summarises products but does not hold label text, and I did not check the general label provisions of the Pest Control Products Regulations.
