The R.C. Harris Water Treatment Plant is a striking art deco facility on the Toronto lakefront, operating since 1941. Often called the “Palace of Purification,” it supplies nearly half of the city’s drinking water. The architecture is grand and meticulously preserved, with marble walls, bronze fixtures, and cavernous interior halls. The plant has served as a filming location for numerous movies and television shows, often depicted as a dramatic institutional or sinister headquarters. While the buildings are typically closed to the public, the grounds remain accessible year-round. Visitors can stroll the landscaped areas, enjoy views of Lake Ontario, or relax near the beach. The site offers a quiet escape with a timeless atmosphere, ideal for walking, picnicking, or simply pausing by the water.

One of Toronto's most important symbols and well-known landmarks is the CN Tower. The tower's top level is where the world's highest observation deck is located, offering visitors a stunning view of Toronto's skyline. The tower's third level houses a high-class restaurant with spectacular vistas, and a cafe occupies the level below. The tower serves a practical purpose, too — it is a major Canadian telecommunications hub.

For an invigorating swim, Embros Thermae, also called The Therma, is an enormous pool with thermal springs, surrounded by circling rocks.
