Every sip of tap water in Toronto contains a small dose of fluoride — the same chemical found in toothpaste.
The idea sounds simple enough: fluoride strengthens teeth, right?
But the full story is a bit more complicated.

Where It Started
Back in the 1940s, a small U.S. town called Grand Rapids added fluoride to its water supply.
A few years later, researchers noticed the town’s residents had fewer cavities.
That single study kicked off a global movement — and now, over 70% of Canadian cities add fluoride to public water.

Why It’s Controversial
Here’s the nuance: Fluoride does help teeth — when applied topically (like toothpaste or mouth rinse).
But drinking it every day is a different story.
Toothpaste tubes even carry a warning label: “Do not swallow.”
Why? Because excess fluoride can lead to fluorosis — white or brown spots on teeth, and in severe cases, bone issues.
For adults, the small amount in tap water isn’t alarming.
But for children under 18, whose bodies are smaller and still developing, long-term exposure can accumulate faster than expected.

Modern Questions
Today, people are asking:
If we already brush twice a day with fluoride toothpaste,
why do we also need it in our water supply?
Especially when Toronto’s water already passes through miles of old pipes, picking up trace metals, chlorine, and other substances on the way to your glass.

It’s Not Just Fluoride
Tap water can legally contain dozens of trace contaminants — from agricultural run-off to microscopic residues of prescription drugs.
Each one is technically “within limits,” but those limits don’t account for years of daily consumption.
That’s why more homeowners are turning to reverse osmosis (RO) — the same filtration process used in hospitals, restaurants, and even submarines.

See It In Action
The system sits under your sink inside the cabinet: a compact filter stack + storage tank. It’s quiet, uses no power, and feeds a small drinking faucet beside your main tap. The tank keeps water ready so flow is instant. Typical maintenance: pre/post filters every 6–12 months; membrane every 2–3+ years.
