The debate over Billy Bishop Airport isn't just about jets vs. noise, it's about future of Toronto’s waterfront. For many, the harbour is cottage country. Do we take that away for increased flights? Or continue to restore the connection to Lake Ontario? https://t.co/uqOx1oVRsR

Great night for water.

20% of world’s surface fresh water is flowing by the Island but taking water for granted turned this privilege into a crisis. Lack of investment in proper sewage treatment was a red flag. Montreal warning residents of water shortages this summer. https://t.co/pYo0YQ5Fl4

Today is the Swim Drink Fish Gala, supporting the Waterkeeper mission to get people back to the water’s edge. With projects like the Wave Prize & the Binnagami project, we are getting people off screens & back to the water that makes swimmable drinkable fishable water possible

Unexpected failure causing sewage bypasses into. Ocean. Community told not to flush toilets, use showers or do laundry until bypass ends. And stay out of water. https://t.co/HPP31GKCEj @swimdrinkfish @waterkeepermark

Toronto's aging infrastructure means a heavy downpour quickly triggers sewer overflows. Engineering fixes take decades, but honest communication shouldn't. Why the City needs to ditch the PR spin and tell the truth about our water quality https://t.co/iu1ueXNQma

While historic schools like Yale fiercely document and preserve their history in brick and stone, Queen's is defining its legacy by how it choosing to reconnect with and restore a living ecosystem. https://t.co/gnqbYJzQzb #yale #queens @swimdrinkfish

Every time it rains in Toronto our sewers overflow into Lake Ontario. We are drifting toward a dangerous future, but art might just be the thing that saves us. Here is why the Swim Drink Fish Art for Water gala matters now more than ever: https://t.co/hgEc3pabHE

Blue Flag status isn't just an award it’s a promise - the water is clean, the beach is safe, & management is sustainable. Huge congrats to the 23 Canadian locations leading the way for 2026. See if your local beach made the list: https://t.co/zhLzRNMdUX] @swimdrinkfish #BlueFlag

Why does it feel so incredible to have a swimming pier in the middle of your city? https://t.co/IHZjAkZfF9

Polluters pay. ArcelorMittal Exploitation Minière Canada hit with a record-breaking $100 MILLION fine for illegally dumping toxic, acidic & high-metal effluents into Quebec waterways. The historic fine will help fund environmental restoration projects. https://t.co/kE9TaydL7X

Swimmable water isn't a "nice-to-have" luxury; it’s the democratic baseline for a functioning society. It’s time we stop treating clean water as an optional perk. https://t.co/dcFtMuTHnJ @swimdrinkfish @swimguide @LOWaterkeeper

54 years today since Pierre Trudeau & Richard Nixon launched the Great Lakes Water Quality Agreement. Despite home to voters who decide elections, have not seen this level of bilateral leadership on watershed since. Need to bring that same energy back to the water. @LOWaterkeeper

A couple billion. That’s the price tag on the massive effort to fix a century of nuclear waste in on Lake Ontario’s North Shore. But the cost of silencing a debate about the future is much higher. https://t.co/TP3cSSRb6w
