The country with the longest coastline is Canada. Stretching over 202,080 kilometers, Canada's extensive coastline is a result of its vast geographical size and numerous islands. This immense coastline encompasses a variety of ecosystems, including rocky shores, sandy beaches, and coastal wetlands. Canada’s coastal regions are significant for biodiversity, tourism, and economic activities such as fishing and shipping. The coastline also plays a crucial role in the nation's identity and cultural heritage, connecting communities to the ocean.
