Here’s where it gets slightly controversial. Does Canada’s coastline include all those little islands up north? Yes, according to the CIA World Factbook (yes, spy agencies track this stuff). The measurement counts every island’s shoreline.
If you only count the mainland coastline, Canada would lose to Indonesia. But the world agrees: every square inch of land counts. So, Canada wins fair and square. Take that, geography nerds.

Also, fun side note: Monaco has the shortest coastline—just 5.6 kilometers. You could walk the entire country’s beachfront before finishing your morning baguette. Canada’s coast is 36,000 times longer. Talk about existential scale.
Why does this matter? (Spoiler: it’s about more than bragging)
Having a long coastline is not just trivia—it shapes a country’s identity, economy, and climate. Canada has the largest marine territory on Earth, controlling rich fishing grounds and shipping routes.
It also means massive challenges: protecting shorelines from erosion, oil spills, and climate change. Melting Arctic ice is opening new waters, but also threatening Indigenous communities who’ve lived along these coasts for millennia.
And let’s be real—if you’re a Canadian, you probably haven’t seen most of your own coastline. I mean, who has time to visit 200,000 kilometers of beaches? That’s a lifetime road trip.
