Is Canada A Landlocked Country

No It is not. It borders the arctic circle and the Atlantic and Pacific oceans. The Hudson bay is large enough to be considered a sea, so no, Canada is not a landlocked country. There are possibly landlocked provinces or districts, but Canada has many Ports of Call.

No. Since it is due north of the mainland United States and spans the same continent it also shares access to the Atlantic ocean to the east and the Pacific ocean to the west.  In addition, it has access to the Artic ocean to the north.

Canada is the farthest thing from a landlocked country. Canada has the longest coastline of any country in the world and borders three of the world's four oceans. Adding to an earlier response: The provinces of Alberta and Saskatchewan are landlocked.
