How far north can you drive in Canada and what are the limitations or restrictions on driving to the northernmost regions of the country?

You can drive as far north as Inuvik in the Northwest Territories on a road called the Dempster Highway. However, beyond Inuvik, there are limited roads and infrastructure, making it difficult to drive further north. The northernmost regions of Canada, such as the Arctic islands, are only accessible by air or sea due to the harsh terrain and extreme weather conditions.
