Toronto’s tap water is sourced from Lake Ontario and undergoes rigorous testing by the city’s water division. They run it through a multi-step treatment process that includes filtration, ozonation, and a bit of chlorine to kill any leftover bugs. Honestly, the city’s water quality is monitored so often it’s almost overachieving—they test for over 200 contaminants on a regular basis.
But here’s the ironic twist: the water leaving the treatment plant is top-notch. The real issue is what happens after it leaves the plant. That’s where your building’s pipes—especially in older downtown homes—can play a little game of “what’s that sediment?”
Old pipes, new worries (and a bit of ick).
If you’re renting a charming Victorian walk-up or a 1970s low-rise in Little Italy, you might be dealing with lead or copper pipes. The city has been replacing lead service lines, but it’s a slow process. If your building hasn’t been updated, letting water run for 30 seconds before drinking can help flush out any metallic taste.
That slight smell of “swimming pool” you notice? That’s chlorine, and it’s there on purpose to keep bacteria from partying in the pipes. Some people hate the taste, but a quick run through a Brita filter or even leaving it in the fridge for an hour neutralizes that chlorine zip. I do it myself, and it makes a world of difference.
