Ontario
The breathtaking four-seasonal palette of Ontario's vast wilderness, endless forests and abundant wildlife awaits. Around 40% of Canada’s population lives here for good reason: Ontario is larger than France and Spain combined. Over 250,000 lakes, including the Great Lakes bordering the US, contain a fifth of the planet's fresh water.
