The N.W.T. Department of Environment and Natural Resources killed a wolf at the Yellowknife dump Tuesday.
Renewable resources officer Ian Ellsworth said they killed the animal because it didn't show any fear of humans.
Ellsworth said wolves can behave like bears — once they get used to a food source, they'll keep coming back.
"If you get between them and a food source they could become aggressive," he said.
"Usually they don't. In normal circumstances, once a wolf sees a person they take off right away. Obviously this one found a food source and was intent on staying there."
The wolf was a medium-sized male.
Ellsworth said the department has been receiving complaints about wolves around Yellowknife for about a week.
He warned people to keep dogs on their leash and keep possible food sources in their yards secure.
