Ontario Attractions Guide
Ontario is Canada's most populous province and its most visited — home to the country's biggest city, its capital, and its most famous waterfall. From the skyscrapers of Toronto to the mist of Niagara Falls and the gothic towers of Parliament Hill, these are the must-see attractions worth building your trip around.
Toronto
- CN Tower (加拿大国家电视塔) — The 553-metre icon that defined Toronto's skyline; the glass-floor LookOut level and the 342-metre EdgeWalk (the world's highest hands-free walk) are the signature experiences.
- Royal Ontario Museum (皇家安大略博物馆) — Canada's largest museum of natural history and world cultures, with standout galleries on dinosaurs, ancient Egypt, and Indigenous art, inside the unmistakable "Crystal" extension.
- Distillery District (酿酒厂区) — A pedestrian-only village of Victorian-era industrial buildings housing galleries, cafes, and boutiques; the Christmas Market here draws over a million visitors each winter.
- Casa Loma (卡萨罗马城堡) — A 98-room Gothic Revival castle with secret passageways, an 800-foot tunnel, and gardens, built by financier Sir Henry Pellatt in 1914; free-roaming audio tours cover every floor.
- Ripley's Aquarium of Canada — The shark-filled Dangerous Lagoon moving walkway, daily dive shows, and a ray touch tank, right next to the CN Tower — plan 2 to 3 hours.
- Toronto Islands — A 15-minute ferry from the Harbourfront lands you on car-free islands with beaches, bike paths, and the best skyline view in the city; Centreville Amusement Park keeps kids busy in summer.
Niagara Falls
- Horseshoe Falls — The largest of the three falls and the reason everyone comes; Table Rock Welcome Centre's viewing platforms put you within metres of the plunging water (free to view from the promenade).
- Journey Behind the Falls — Elevators descend to tunnels that open onto observation decks directly behind the curtain of Horseshoe Falls — the closest you can get to the falls on foot.
- Niagara City Cruises — The Canadian boat tour (formerly Hornblower Niagara Cruises) sails from below Clifton Hill right into the mist of Horseshoe Falls; red ponchos are provided and you will need them.
- Clifton Hill — The famously kitschy entertainment strip of wax museums, haunted houses, and the Niagara SkyWheel — pure fun for families, an easy walk from the falls.
- Niagara-on-the-Lake — A 20-minute drive north, this 19th-century colonial town of wineries, boutique inns, and the Shaw Festival Theatre makes the perfect half-day pairing with the falls.
Ottawa
- Parliament Hill (国会山) — The neo-Gothic seat of Canada's government; the summer Changing of the Guard ceremony and evening Northern Lights sound-and-light show run seasonally (free).
- National Gallery of Canada (加拿大国家美术馆) — Guarded by the giant bronze spider Maman, with one of the finest collections of Indigenous and Canadian art in the world, steps from ByWard Market.
- Rideau Canal — A UNESCO World Heritage Site that doubles as a boating route in summer and the 7.8 km Rideau Canal Skateway — the world's largest skating rink — in winter.
- Canadian Museum of History — Across the river in Gatineau with postcard views of Parliament, featuring the spectacular Grand Hall of First Peoples' totem poles and the Canadian History Hall.
Practical Tips
- Best season: May to October covers the peak visiting window — warm weather, open attractions, and patios. September brings fall colours across the province; winter is ideal for the Rideau Canal Skateway and Toronto's indoor attractions.
- Getting around: Toronto is served by the TTC subway and streetcars, but you will want a car for Niagara Falls and Niagara-on-the-Lake (about 90 minutes from downtown). Ottawa's LRT connects the downtown core; Via Rail links Toronto and Ottawa in about 4 hours. Book CN Tower and major museum tickets online in advance during summer weekends.
Frequently asked questions
Q: Can I do Niagara Falls as a day trip from Toronto?
A: Yes — it is about 90 minutes each way by car or GO Transit bus. Budget at least 6 hours at the falls for the boat cruise, Journey Behind the Falls, and the Table Rock viewpoints. Adding Niagara-on-the-Lake turns it into a full but comfortable day.
Q: Which Toronto attraction is best for families with young kids?
A: The Toronto Islands and Ripley's Aquarium are the top picks — the islands have beaches and Centreville Amusement Park, and the aquarium's tunnel and touch tanks hold young children's attention for hours. Pair them across two days with the Distillery District for the adults.
