Canada ( //) is a country occupying most of northern North America, extending from the Atlantic Ocean in the east to the Pacific Ocean in the west and northward into the Arctic Ocean. It is the world's second largest country by total area. Canada's common border with the United States to the south and northwest is the longest in the world.
It is estimated that 154 countries and territories granted visa-free access to ordinary Canadian passport holders.

Visitors engaging in activities other than tourism, including unpaid work, may require a visa or work permit
