Morning: Start With the CN Tower

Every great Toronto city break starts the same way, by looking up.
The CN Tower is the symbol of this city. According to several reputable sources, it was once one of the tallest freestanding structures in the world, and it still dominates the Toronto skyline today at 1,168 feet, or 356 meters tall.
Book your tickets online before you go. From what we discovered while researching, most major attractions in the city, especially the CN Tower, get busy fast and require advance bookings since most attractions require advance booking online, especially the CN Tower.
Take the elevator up to the LookOut Level. On a clear morning, you can see Lake Ontario stretching out blue and endless, with the Toronto Islands floating just offshore. If you are feeling brave, the EdgeWalk lets you walk around the outside of the tower, 116 stories above the ground, with nothing but a harness between you and the city below.
It sounds terrifying. It also sounds like the kind of story you will tell for years.
Late Morning: Ripley's Aquarium and a Walk Through the Financial District

Right next to the CN Tower sits Ripley's Aquarium. It is a favorite for families, with a glass tunnel that puts sharks and stingrays gliding right over your head.
After that, take a slow walk north into the financial district. The contrast is striking. Glass towers shoot up around you, but tucked between them are small parks, public art, and the Hockey Hall of Fame, a must for anyone who loves Canada's national sport.
Lunch: St. Lawrence Market

No first-time visit to Toronto feels complete without St. Lawrence Market. This historic market has been feeding the city for generations, and it still buzzes with vendors selling everything from fresh seafood to local cheese.
The must-try here is the peameal bacon sandwich. It is simple. Just bacon, a soft bun, and mustard. But somehow it tastes like Toronto in a single bite.
Based on trusted travel resources, browsing St. Lawrence Market is completely free, making it one of the best low-cost things to do in downtown Toronto since St. Lawrence Market browsing is one of the city's free activities.
Afternoon: Nathan Phillips Square and Yonge-Dundas Square

From the market, head toward Nathan Phillips Square, the open plaza in front of Toronto's City Hall. In summer, you might catch a festival or food truck event. In winter, there is an outdoor skating rink that locals genuinely use, not just tourists.
A short walk away is Yonge-Dundas Square, often called Toronto's version of Times Square. Giant screens, street performers, and a constant flow of people make it one of the most photographed downtown Toronto sightseeing spots.
Evening: Dinner and Nightlife on King Street West

As the sun starts to dip, head toward King Street West. This stretch of the Entertainment District comes alive at night, with restaurants spilling onto patios and music drifting out of bars.
According to several reputable sources, the 504 streetcar runs the full length of King Street, making it easy to hop on and explore without worrying about parking, since the 504 streetcar runs the length of King Street West.
For dinner, try one of the many international spots that reflect Toronto's food scene, from upscale Canadian cuisine to casual Asian fusion. After dinner, this is where Toronto nightlife really shows itself. Rooftop bars, live music venues, and late-night patios keep the energy going well past midnight.
If clubs and cocktail lounges are not your thing, the Entertainment District also has theaters and live performance venues, so you can catch a show instead
