Issues related to Canada geese

As Canada geese are increasingly numerous and produce nearly 1 kg of feces per day, they can cause significant problems.

Health and safety risks

  • Sanitation issues
  • Disease transmission (e.g. salmonellosis)
  • Protecting young people from intimidating or aggressive behaviour
  • Collisions, especially with cyclists or snowboarders
  • Disturbances to sports and recreational activities

Environmental damage

  • Aesthetic degradation of buildings and ground due to manure 
  • Damage to lawns from intensive grazing 
  • Shoreline erosion 
  • Water pollution

Reduced disturbances

To limit the negative impacts of Canada geese in parks, several solutions have been developed: 

  • Feeding wild birds is prohibited
  • Reducing short turf areas where Canada geese feed by adapting landscaping and maintenance practices 
  • Using trained dogs or remote-controlled devices to scare geese away
  • Installing temporary nets to block access from bodies of water 
  • Regularly clean manure, especially on trails and in playgrounds
