The Downtown core is the economic powerhouse of Toronto, although it lacks the cultural appeal of the outlying districts. Many of Toronto's larger attractions are located here, however, so it's an essential part of any visit to Toronto.
Dozens of towering glass, concrete and steel monoliths are a must-see for architecture enthusiasts. Toronto's Financial District is actually quite compact and walkable, even in inclement weather. That's because of the "PATH"  - 27 km (16 miles) of interconnecting passageways under the streets that feature more than 1,200 stores and services. Street entrances to the subterranean walkway are indicated with "PATH" signage.
The nearest airport to Toronto's financial district is the Toronto Island Airport , which is located across a narrow channel from the foot of Bathurst Street in the Harbourfront district. The main commercial airline serving the airport is Porter , operating year-round flights to New York City, Chicago, Montreal, Quebec City and Halifax as well as winter flights to Mont-Tremblant. Air Canada Express also offers service to Montreal. Porter operates a free bus for its passengers between the airport and Union Station; alternately, you can take the 509 streetcar from Queen's Quay and Bathurst, a few blocks from the airport, to Union Station.
Toronto's main railway station, Union Station is located at the foot of the financial district, on Front Street between York and Bay Streets. All commuter rail lines in the city run to and from Union Station and are run by Go Transit. Trains run all day on weekdays and weekends on the Lakeshore line from Hamilton in the west to Oshawa in the east, all the other lines run only at rush hour on weekdays. All intercity trains in Toronto run to Union Station and are operated by Via Rail  and Ontario Northland . For more information on intercity and commuter rail services to Toronto, see the Toronto city article.
The financial district is well served by the Yonge-University-Spadina line with Queen, King, Union, St Andrew and Osgoode stations all lying in the district. The Toronto subway is operated by the TTC  and the fare is $3.00.
Many streetcar lines run through or terminate in the financial district. The 504 line runs along King street, through the centre of the neighbourhood, The 501 line runs along Queen street at the north end of the district and the 502, 503 and 508 lines terminate in the district. The streetcar lines are run by the TTC  and the fare is $3.00.
The easiest way to find downtown Toronto is to locate the CN Tower, and head towards it. Be advised that Toronto is considered a very dangerous city to bike in by many people, and accidents are frequent. Stick to less populated roads, and be aware of people and vehicles around you.
Art Gallery of Ontario, 319 Dundas St W (St Patrick subway station), . Home to many famous pieces of art ranging from very recent to artwork hundreds of years old. Artists from Monet to Warhol are represented here and the AGO has one of the largest collections of Henry Moore sculptures in the world.
CN Tower, 301 Front Street West, +1 416 868-6937, . Su-Th 9:30AM-10PM, F-Sa 9:30AM-10:30PM (for specific attractions - prices vary by access). The much-acclaimed CN Tower is Toronto's most recognizable and famous feature, and was the world's tallest free-standing structure until the Burj Dubai surpassed it in September of 2007. It is still the tallest free-standing structure in the Americas. At a dizzying 553 m high, a visit is worth it for the view of the city alone. Visitors can look out from behind glass windows or go to an outside observing area to look through a metal screen. It attracts large numbers of tourists; best times are weekdays in the morning. Wait times at peak times can be as high as one hour to buy a ticket and two hours for the elevators. Peak attendance times are weekends in summer, especially last week of June and first week of July when Toronto gets hit with massive crowds for both Canada Day and U.S. Independence Day. Visitors can jump up and down on the thick glass floor in parts of the observatory (the view from the floor downward essentially shows the base of the tower). 360, the revolving restaurant, is located in the main deck, but isn't particularly renowned. Restaurant diners with reservations can avoid the queues for the observatory, and at night the lights from distant Rochester, New York are visible over the lake. Approx. $20 (budget) or $28 to go up. $12 additional to go above main lounge to the higher SkyPod, which is worth it. The additional height over the skyline is really impressive, and the SkyPod's diagonal windows and smaller crowd result in less annoying reflections in your photos. There is no parking garage at CN Tower itself, but there are several public and private parking garages within walking distance, all of which are horribly expensive. CN Tower is right next to Metro Toronto Convention Centre and the Rogers Centre, so check their schedules to see if they will also be drawing crowds on the day of your visit.
City Hall and Nathan Phillips Square, (Queen subway station), . Toronto's modernist City Hall designed by Finnish architect Viljo Revell and was completed in 1965. Nathan Phillips Square features the Freedom Arches and underneath, a reflecting pool that turns into a skating rink in the winter.

Toronto Eaton Centre, Yonge and Dundas (Dundas or Queen subway stations), . Over 285 shops and services, including most of North America's most popular brands. The flock of fibreglass Canadian geese suspended from the ceiling are a popular photo op. On the one hand, Americans will find prices to be quite high (there is a reason why nearly every able-bodied Canadian tries to shop like crazy in America at least once each year), but on the other hand, Canada supposedly regulates textile quality more strictly than the U.S., so apparel in theory should last a little bit longer.
