The CN Tower and Downtown Toronto
Toronto is the beating heart of Ontario, and the CN Tower is its most recognizable symbol. Standing at 553 metres, it held the title of world’s tallest free-standing structure for over 30 years.
The observation deck and the famous glass floor offer breathtaking panoramic views of the city and Lake Ontario. For the adventurous, the EdgeWalk lets you walk around the tower’s outer rim — fully harnessed, of course.
Beyond the CN Tower, Toronto’s downtown is packed with attractions. The Royal Ontario Museum (ROM), Ripley’s Aquarium of Canada, and the vibrant Kensington Market are all worth your time.

Algonquin Provincial Park: Ontario’s Natural Treasure
For those who love the outdoors, Algonquin Provincial Park is unmissable. Established in 1893, it spans over 7,600 square kilometres of forests, rivers, and lakes in central Ontario.
The park is renowned for canoeing, hiking, and wildlife watching. Moose sightings along Highway 60 are common, and the park’s fall colours in September and October are among the most spectacular in North America.
What to do in Algonquin Park:
- Canoe one of over 2,000 lakes and rivers
- Hike the Centennial Ridges Trail for panoramic views
- Camp at one of 1,300+ backcountry sites
- Visit the Algonquin Visitor Centre to learn about local ecology

Ottawa: Canada’s Capital, Ontario’s Cultural Hub
Ottawa often gets overlooked in favour of Toronto, but Canada’s capital city is one of Ontario’s richest cultural destinations. As the seat of federal government, it’s home to world-class museums and historic sites.
The Parliament Hill buildings are a must-see, especially during the summer Sound and Light Show. The Canadian Museum of History (across the river in Gatineau, Quebec) and the National Gallery of Canada round out an impressive cultural corridor.
Top spots in Ottawa:
- Parliament Hill and the Rideau Canal (a UNESCO World Heritage Site)
- ByWard Market for local food and shopping
- The Canadian War Museum
- Winterlude festival in February

Thousand Islands: Where the River Meets the Rockies of Ontario
The Thousand Islands region, stretching along the St. Lawrence River near Kingston, is one of the most scenic areas in all of Canada. The region actually contains over 1,800 islands, many of which are privately owned with stunning historic homes and cottages.
Boat tours through the islands are incredibly popular from May through October. Boldt Castle, accessible by boat from the Canadian side, is a particularly striking landmark with a romantic — and tragic — history.

Towns like Gravenhurst, Bracebridge, and Huntsville offer boutique shopping, local dining, and access to stunning lake country. The Muskoka region is also home to popular resorts and rental cottages for those looking to unplug.
Why Muskoka stands out:
- World-class freshwater lakes for swimming and boating
- The Muskoka Heritage Place living museum in Huntsville
- Gravenhurst’s historic steamship cruises on Lake Muskoka
