The VOICE of Anglers and Hunters since 1928

Wild Pigs in Ontario

The OFAH is extremely concerned about wild pigs becoming established in Ontario. They have already caused widespread problems in Canada’s prairie provinces and many American states.  If the MNRF does not take immediate action, Ontario could have an extensive wild pig problem with severe financial and environmental consequences.  The OFAH is advocating for the eradication of wild pigs in Ontario.

OFAH advocacy spawns action on wild pigs — written by Dr. Keith Munro, OFAH wildlife biologist

The Issue

Wild pigs (wild boar, feral domestic pigs, hybrids) are non-native to North America resulting from farm escapes and intentional releases. They are major a problem because:

  • They reproduce very quickly (sexually mature at 6 months and can have two litters per year with 4-10 piglets each time)
  • They can destroy native ecosystems (damage plant communities and invite invasive species, compete with native wildlife for food and habitat, decrease biodiversity)
  • They are expensive to control (in the US, they have cost an estimated 1 billion annually to the agricultural industry through crop damage, livestock predation and damage to equipment)
  • They can spread disease (brucellosis, trichinosis, hepatitis, African Swine Fever)


The Challenge

Unfortunately, hunting is not the solution to this problem and will in fact make things much worse. Research and management experience from provinces and states that have been dealing with wild pigs for years has shown that hunters removing individual pigs has minimal effect on the population and instead breaks up groups of pigs (called sounders), scatters them across the landscape and teaches them to avoid hunters. This makes control efforts much more difficult and pigs quickly breed to replace any losses. Worse still, unscrupulous hunters in some states have purposely spread pigs in order to take advantage of open seasons in their areas.

What has been shown to work in eradicating wild pigs is identifying and eliminating the entire sounder. This takes dedicated wildlife professionals with specialized techniques such as trapping. This is what the OFAH is advocating for and the MNRF’s pilot study to figure out how to do this in Ontario is the critical first step.


What the OFAH Wants

  • A provincial reporting and monitoring system to deal with wild pigs found on the landscape
  • MNRF to respond to all reported sightings to determine appropriate action
  • All reported escaped wild pigs removed from the landscape
  • Dedicated government staff to train and deal with larger established wild pig populations (trapping, sharpshooting)
  • MNRF to be open and transparent about wild pig escapes and sightings in Ontario by reporting annually to the public
  • MNRF to explore whether wild pigs should be listed under the Invasive Species Act
