Which country does arctica start and stop?

The Arctic region is not confined to a single country; rather, it encompasses parts of several nations including Canada, Russia, the United States (Alaska), Norway, Denmark (Greenland), Sweden, Finland, and Iceland. The Arctic typically refers to areas north of the Arctic Circle, which is located at approximately 66.5 degrees north latitude. Therefore, it begins in northern regions of these countries and extends to the Arctic Ocean. The boundaries of the Arctic can vary depending on the context, such as ecological, geopolitical, or climatic considerations.
