Red foxes likely arrived in Ontario during the last glacial period (approximately 10,000 years ago) via the Bering Land Bridge. This natural land connection between North America and Asia was exposed as sea levels dropped during the Ice Age, allowing animals and plants to migrate between the continents. Once red foxes reached North America, they gradually spread eastward across the continent and eventually reached Ontario.
Human Introduction:
Some populations of red foxes in Ontario may also have been introduced by humans. Historically, red foxes were valued for their fur and were sometimes transported to new regions for hunting or fur farming purposes. These introductions may have inadvertently led to the establishment of new fox populations in Ontario.
