13 Best Sights in Harbourfront, the Entertainment District, and The Financial District, Toronto

The tallest freestanding tower in the Western Hemisphere, this landmark stretches 1,815 feet and 5 inches high and marks Toronto with its distinctive silhouette. The CN Tower is this tall for a reason: prior to the opening of the telecommunications tower in 1976, so many buildings had been erected over the previous decades that lower radio and TV transmission towers had trouble broadcasting. It's worth a visit to the top if the weather is clear, despite the steep fee. Six glass-front elevators zoom up the outside of the tower at 15 miles per hour, and the ride takes less than a minute. Each elevator has one floor-to-ceiling glass wall—three opaque walls make the trip easier on anyone prone to vertigo—and most have glass floor panels for the dizzying thrill of watching the earth disappear before your eyes.

There are four observation decks. The Glass Floor Level is 1,122 feet above the ground. This may be the most photographed indoor location in the city—lie on the transparent floor and have your picture taken from above like countless visitors before you. Don't worry—the glass floor can support more than 48,000 pounds. Above is the LookOut Level, at 1,136 feet; one more floor above, at 1,151 feet, is the excellent 360 Restaurant. If you're here to dine, your elevator fee is waived. At 1,465 feet, the SkyPod is the world's highest public observation gallery. All the levels provide spectacular panoramic views of Toronto, Lake Ontario, and the Toronto Islands, and on really clear days you may even see the mist rising from Niagara Falls to the south. Adrenaline junkies can try the EdgeWalk attraction, which allows harnessed tower goers to roam "hands free" around a 5-foot ledge outside the tower's main pod. Reservations are required.

On the ground level, the Gift Shop at the Tower has 5,000 square feet of shopping space with quality Canadian travel items and souvenirs, along with a shop selling Inuit art. Displays and exhibits throughout the building feature the history of the Tower and its construction; how the Tower works today, including engineering components that make it such a unique attraction; and a dynamic weather display. Peak visiting hours for the stunning views are 11 to 4.

Even if you aren't a hockey fan, it's worth a trip to see this shrine to Canada's favorite sport. Exhibits include the original 1893 Stanley Cup, as well as displays of goalie masks, skate and stick collections, players' jerseys, video displays of big games, and a replica of the Montréal Canadiens' locker room. Grab a stick and test your speed and accuracy in the Goodyear Shoot Out virtual experience, or strap on a goalie mask and field shots from big-name players with the Shut Out computer simulation. The grand building, a former Bank of Montréal branch designed by architects Darling & Curry in 1885, is covered with beautiful ornamental details—note the richly carved Ohio stone and the Hermès figure supporting the chimney near the back. At the corner of Front and Yonge Streets, the impressive 17-foot bronze statue Our Game is a good photo op. Entrance is through Brookfield Place on the lower level.

North America's largest aquarium contains more than 450 species of marine life spread out between 45 exhibit spaces. Maintaining their philosophy to "foster environmental education, conservation, and research," Ripley's also lives up to its reputation as a wow-inducing entertainment venue. One exhibit simulates a Caribbean scuba diving experience, complete with bountiful tropical fish, coral reefs, and a bright blue sky above. Sharks are a dominant theme: you can wind your way through tunnels that take you right into the almost 80,000-gallon shark tank, which houses three species of sharks and more than 5,000 other aquatic animals. The shark pattern on the roof is an unexpected treat for visitors peering down on the aquarium from the top of the CN Tower.

These 14 narrow, tree-lined islands in Lake Ontario provide a gorgeous green retreat with endless outdoor activities. The more than 230 hectares of parkland are hard to resist, especially in the summer, when they're usually a few degrees cooler than the city.

Sandy beaches fringe the islands; the best are on the southeast tip of Ward's Island, the southernmost edge of Centre Island, and the west side of Hanlan's Point. A portion of Hanlan's Beach is officially "clothing-optional"—Ontario's only legal nude beach. In the summer, Centre Island has bike and rowboat rentals. Bring picnic fixings or something to grill in one of the park's barbecue pits, or grab a quick (but expensive) bite at one of the snack bars or cafés. (Note that the consumption of alcohol in a public park is illegal in Toronto.) There are also supervised wading pools, baseball diamonds, volleyball nets, tennis courts, and even a disc-golf course. Winter can be bitterly cold on the islands, but snowshoeing and cross-country skiing with downtown Toronto over your shoulder are appealing activities.

All transportation on the islands is self-powered; no private cars are permitted. The boardwalk from Centre Island to Ward's Island is 2½ km (1½ miles) long. Bikes are allowed on all ferries, or you can rent one for an hour or so once you get there. Bike rentals can be found south of the Centre Island ferry docks on the Avenue of the Islands.

You may want to take one of the equally frequent ferries to Ward's Island or Hanlan's Point from Jack Layton Ferry Terminal. Both islands have tennis courts and picnic and sunbathing spots. Late May through early September, the ferries run between the docks at the bottom of Bay Street and the Ward's Island dock between 6:35 am and 11:45 pm; for Centre and Hanlan's islands, they begin at 8 am. Ward's Island Ferries run roughly at half-hour intervals most of the working day and at quarter-hour intervals during peak times such as summer evenings. In winter the ferries run only to Ward's Island on a limited schedule. Savvy travellers can also grab a ride from a water taxi along the waterfront.

In the Shangri-La's Lobby Lounge, where guests check in, a band performs, a fireplace soothes, and silk-clad waitresses seemingly float from sunken couch to sunken couch bringing light meals and cocktails to a mix of locals and hotel guests. You can take in the scene over Afternoon Tea, offered seven days a week. This experience starts at $45 per person for a three-tier spread that includes a pot of one of the expertly blended teas—there are two tea sommeliers on staff to explain the 72 varieties of tea. Expect delicate pastries, buttery scones with homemade jam, and clever twists on finger sandwiches, such as brie, apple, and ham on marble rye on the menu.

This historic site is a must for anyone interested in the city's origins. Toronto was founded in 1793 when the British built Fort York to protect the entrance to the harbor during Anglo-American strife. Twenty years later, the fort was the scene of the bloody Battle of York, in which explorer and general Zebulon Pike led U.S. forces against the fort's outnumbered British, Canadian, and First Nations defenders. The Americans won this battle—their first major victory in the War of 1812—and burned down the provincial buildings during a six-day occupation. A year later, British forces retaliated when they captured Washington, D.C., and torched its public buildings, including the Executive Mansion. Exhibits include restored barracks, kitchens, and gunpowder magazines, plus changing museum displays. There are guided tours, marching drills, and cannon firings daily during the summer months. The Fort York Visitor Center has been highly praised for its modern architectural design and exhibits on the founding of York, the changing harbor, and the War of 1812, plus an area displaying rare artifacts related to Toronto and Fort York's history. The grounds of the fort have also become a popular venue for music festivals during spring and summer.

Stretching from just west of York Street to Spadina Avenue, this culture-and-recreation center is a match for San Francisco's Pier 39 and Baltimore's Inner Harbor. The original Harbourfront opened in 1974, rejuvenating more than a mile of city; today a streamlined 10-acre version draws more than 3 million visitors each year. Queens Quay Terminal is a former Terminal Warehouse building that was transformed in 1983 into a magnificent, eight-story building with specialty shops, eateries, and the 450-seat Fleck Dance Theatre. Exhibits of contemporary arts are mounted at the Power Plant, which can be spotted by its tall red smokestack; it was built in 1927 as a power station for the Terminal Warehouse's ice-making plant.

Developed by renowned cellist Yo-Yo Ma and garden designer Julie Moir Messervy, the Music Garden on the south side of Queens Quay is Ma's interpretation of J. S. Bach's Cello Suite No. 1 (which consists of six movements—Prelude, Allemande, Courante, Sarabande, Minuet, and Gigue). Each movement is reflected in the park's elaborate design: undulating riverscape, a forest grove of wandering trails, a swirling path through a wildflower meadow, a conifer grove, a formal flower parterre, and giant grass steps. York Quay Centre hosts concerts, theater, readings, and ateliers. The Craft Studio, for example, has professional craftspeople working in ceramics, glass, metal, and textiles from February to December, in full view of the public. A shallow pond outside is used for canoe lessons in warmer months and as the largest artificial ice-skating rink in North America in winter. At the nearby Nautical Centre, many private firms rent boats and give sailing and canoeing lessons. Seasonal events include the Ice Canoe Race in late January, Winterfest in February, a jazz festival in June, Canada Day celebrations and the Parade of Lights in July, the Authors' Festival and Harvest Festival in October, and the Swedish Christmas Fair in November.

This subterranean universe expanded from existing tunnels in the mid-1970s partly to replace the retail services in small buildings that were demolished to make way for the latest skyscrapers and partly to protect office workers from the harsh winter weather. As each major building went up, its developers agreed to connect their underground shopping areas with others and with the subway system. You can walk from beneath Union Station to the Fairmont Royal York hotel, the Toronto-Dominion Centre, First Canadian Place, the Sheraton Centre, The Bay and Eaton Centre, and City Hall without ever seeing the light of day, encountering everything from art exhibitions to buskers (the best are the winners of citywide auditions, who are licensed to perform throughout the subway system). According to Guinness World Records, the PATH is the biggest underground shopping complex in the world. Maps to guide you through the labyrinth are available in many downtown news and convenience stores. Be aware that large sections of the PATH may be closed on weekends when the office buildings are closed. This can cause particular problems for wheelchair users because not all sections of the underground are fully accessible.

The Rogers Centre is home to baseball's Blue Jays and was the world's first stadium with a fully retractable roof. Rogers Communications, the owner of the Blue Jays, bought the stadium, formerly known as the SkyDome, in February 2005 for a mere C$25 million. One way to see the 52,000-seat stadium is to buy tickets for a Blue Jays game or one of many other events and concerts. You can also take a one-hour guided walking tour: the route depends on what's going on at the stadium, so you may find yourself in the middle of the field, in a press box, in the dressing rooms, or, if a roof tour is available, 36 stories above home plate on a catwalk.

Built under the Gardiner Expressway, the Bentway is part of the city's efforts to reclaim public spaces. The sprawling stretch of land houses whimsical art installations, communal dining and picnic spaces, a gloriously smooth paved pathway built for roller-skating and ice-skating (rentals available at C$10) depending on the season, and various community events, festivals, and concerts.

A five-story architectural masterpiece, this glass-paneled building houses the year-round headquarters of the internationally acclaimed Toronto International Film Festival, which takes place in September. Throughout the year visitors can attend film-related lectures, watch screenings, and enjoy smaller film festivals, including the TIFF Next Wave Film Festival, a film festival with free movies for anyone under 25 that takes place in April. A stellar educational program includes summer camps and ongoing workshops—on how to produce a stop-motion movie, for example. The TIFF Cinematheque, open to the public, plays world cinema classics and contemporary art house films.

Ludwig Mies van der Rohe, a virtuoso of modern architecture, designed a significant portion of this six-building office complex, though he died before its completion in 1992. As with his acclaimed Seagram Building in New York, Mies stripped the TD Centre's buildings to their skin and bones of bronze-color glass and black-metal I-beams. The tallest building, the Toronto Dominion Bank Tower, is 56 stories high. The only architectural decoration consists of geometric repetition. Inside the low-rise square banking pavilion at King and Bay Streets is a virtually intact Mies interior.

Historian Pierre Berton wrote that the planning of Union Station recalled "the love lavished on medieval churches." Indeed, this train depot can be regarded as a cathedral built to serve the god of steam. Designed in 1907 and opened by Edward, Prince of Wales, in 1927, it has a 40-foot-high coffered Guastavino tile ceiling and 22 pillars weighing 70 tons apiece. The floors are Tennessee marble laid in a herringbone pattern (the same that's in Grand Central Terminal in New York City). The main hall, with its lengthy concourse and light flooding in from arched windows at each end, was designed to evoke the majesty of the country that spread out by rail from this spot. The names of the towns and cities across Canada that were served by the country's two railway lines, Grand Trunk (incorporated into today's Canadian National) and Canadian Pacific, are inscribed on a frieze along the inside of the hall. As train travel declined, the building was nearly demolished in the 1970s, but public opposition proved strong enough to save it, and Union Station, a National Historic Site of Canada, is now a vital transport hub. Commuter, subway, and long-distance trains stop here.
