Ontario’s problem pigs

Sightings of free-roaming feral swine in Ontario have risen in recent years despite the animals’ tendency to travel at dawn, dusk and night. Some of these sightings have been made near Ottawa and Kingston. Diane Saxe, Ontario’s Environmental Commissioner, has said that feral hogs are heading north from the United States into eastern Ontario. There have also been reports of wild boars that escaped from Ontario-based farms.

In the early 1900s, wild boars were introduced in many eastern U.S. states for hunting. Some of these boars bred with escaped farmed swine, adding combined genetics to the present day population of feral hogs in the area.

By wallowing in and rooting around in forests and wetlands, these invasive hogs in Ontario can make damaging pigsties of local ecosystems. This behaviour can disturb habitats important to native species, many of which are already stressed by habitat fragmentation.

Feral hogs can also carry diseases, such as E. coli, giardia, rabies, foot-and-mouth disease, salmonella, anthrax and encephalomycarditis, that are harmful to humans, wildlife and livestock. They can also damage farmed crops.

Tick talk: how to stay tick-free this summer


What will the future hold for Ontario’s wetlands?


  1. Tom Shields

    Can these be hunted in Ontario? What license is needed?

  2. Chris

    you may and no license needed just need to tell local MNRF office where and when you shot it

    • Tom Shields

      Thanks for the reply. You do need a small game license, but do not need a tag and there is no season (open season all the time).

    How far in Northern Ontario have these been spoted?

    • Rebecca Rogge

      I’ve heard of a few in Almaguin (East Parry Sound) south of North Bay.

  4. Glenn Sollie

    There should be bounty on these, as there once was on coyotes.

    It’s been made illegal to hunt, possess or transport the wild boars in New York State. This is because it had been found that, in Tennessee, if hunting was allowed, it was an inefficient way to control the population. Hunting disburses the boars and they multiply very quickly. Also people then get boars and release them in certain areas to get income from the sport of hunting. I hope Canada will take a page from New York’s policy before it’s too late. http://www.dec.ny.gov/animals/70843.html

      Sure just leave them alone, they won’t multiply!

    • Steve

      Thats a crock of shit everyone knows hunting keeps population under control whether it’s deer ,bear or wild hogs , you just said they multiply at an astounding ratel so left unchecked they would be rampant everwhere.

      Actually it is allowed…need to read it all:

      “Hunting or Trapping of Eurasian Boars is Prohibited
      Hunting or trapping of Eurasian boars is now illegal in New York State. A new regulation was adopted on April 23, 2014 that prohibits the hunting or trapping of free-ranging Eurasian boar statewide. The regulation provides exceptions for law enforcement officers, farmers, and landowners who are authorized by DEC to take Eurasian boar to alleviate nuisance, property damage, or threats to public health or welfare. This regulation is necessary to ensure maximum effectiveness of DEC’s statewide eradication efforts.”

    I know that in Sweden wild boars is a real problem, at least in some areas.
    I do not know how they approach the problem there, but i do not believe that open season year round is a good way to handle it.

    All these invasive species should be eliminated before the population gets too big to control, like it is in the U.S.
