Public consultation on predacide use in Canada

Health Canada’s Pest Management Regulatory Agency (PMRA) is currently offering a public consultation to determine how the humaneness of pesticides used to kill predators (predacides) could be considered during their approval and use.

Wildlife Defence League (WDL) has made a submission and we’re encouraging our supporters to also participate in the consultation before the April 18th deadline. Please see the consultation questions below, as well as our feedback.

Consultation Questions:

  1. Should PMRA include humaneness considerations as part of the pesticide registration process for products intended to control large vertebrate predators? If so, what would be the best options and approaches for doing so?

  2. Should PMRA develop public information, such as best practices / standards on humaneness considerations, that pesticide users could take into account when deciding whether to use a pesticide for controlling large vertebrate predators?  If so, what kind of information would be most useful?

  3. In either case, what should be the parameters to measure humaneness?

Visit the consultation page for more background information. Feedback can be submitted via email to hc.pmra.publications-arla.sc@canada.ca. Please be sure to personalize your response and do not just copy and paste.


It is the position of the Wildlife Defence League that humaneness must be a central part of all wildlife management strategies. The Canadian Veterinary Medical Association’s pest control position statement states that “the welfare implications, safety, and ecological impact of the chosen strategy should always be considered”. 1

Predacides such as sodium fluoroacetate (Compound 1080), sodium cyanide and strychnine are inhumane, as they result in severe and often prolonged suffering. Animals that ingest these poisons can experience seizures, cessation of breathing, hyperthermia, extreme suffering and death from exhaustion or asphyxiation. Death may occur within 1-2 hours but, depending on the dose ingested, it can take up to 24 hours or longer for the animal to die. 2,3

These predacides fail to meet the Canadian Council on Animal Care guidelines, which defines a killing method as humane if it causes rapid (immediate) unconsciousness and subsequent death without pain or distress. 4 They also fail to meet the Canadian Veterinary Medical Association guidelines for humane pest control. 5

Predacides are indiscriminate killers. The baited poisons used to attract the target species inevitably attract other animals (including pets), who suffer the same cruel fate. Secondary poisoning of animals that scavenge on the toxic carcasses is an additional concern. 6 The widespread impact of these poisons is likely not fully understood either, as they may not always be directly lethal to non-target animals, but may seriously compromise reproduction, immune function, overall fitness, and longevity. 7

Ultimately, these predacides cannot be used humanely, due to the very nature of the products themselves, as well as the risks they pose to biodiversity, entire ecosystems, and public safety. Existing animal welfare guidelines, as outlined in this submission, offer a baseline for humaneness considerations. As wildlife face increased human pressure, it’s crucial that root causes of conflict be addressed, rather than reliance on lethal strategies that often fail to address these root causes. WDL is calling on the Minister of Health and the Pest Management Regulatory Agency (PMRA) to include humaneness considerations in the pesticide registration process and to prohibit these predacides under the Pest Control Products Act.

Wildlife Defence League launches "Trophy-Free BC" initiative to ban cougar, lynx & bobcat hunting

Following a successful campaign to end the hunting of grizzly bears in British Columbia, Wildlife Defence League has launched a new #TrophyFreeBC initiative to ban the hunting of cougar, lynx and bobcat in the province. To accomplish this goal, the initiative will involve fieldwork, advocacy, education and research.

During late fall, winter and early spring, wild cats in the province are killed for trophy. Hunting cougar, lynx and bobcat is extremely difficult so hounds (often equipped with GPS collars), are used to track, chase and tree the animals. As the cat sits exhausted and defenceless, the trophy hunter follows the GPS signal to its location. While standing near the base of the tree, the animal is shot. Shooting at extreme angles and with tree branches often obscuring sightlines, a clean kill is never guaranteed.

There are glaring ethical issues with these hunts. For instance, while it’s illegal to kill a mother cougar in the presence of her kittens, killing a mother while she has left her kittens in the safety of a nursery or rendezvous site is legal. Orphaned kittens are often left to starve or are attacked by other predators and rarely survive. The use of hounds to hunt wild cats can separate mothers from their young; puts the dogs at unnecessary risk of injury and death and ultimately provides an unfair advantage that should not fall under the category of fair-chase.

Join us today as we seek to protect these iconic wild cats from inhumane, outdated and unethical hunting practices.
