this summer was the first time I was swimming in lake Ontario around the island. I used to be unsure of the water but am convinced that its fine to swim in. I haven't gotten sick, grown any extra limbs nor did I see any shite or garbage floating around in the water. ive been to beaches in Europe, Barcelona notably, where the water looked more disgusting than in Toronto.
They have stopped taking water quality measurements for this year.
As a person who spends a lot of time in Lake Ontario, I have to say that this year the water quality around Toronto has been particularly bad visually (lots of floating stuff) and smelly too. I spend hours at a time in the water hunting for treasure and wear chest waders and rubber gauntlets in the dubious area.
I do swim though but generally on the South beaches of the island. Hanlans hasn't seemed so clean this year, in spite of the green-OK water tests.
I can't wait until the city starts issuing those sewage spill advisories.
i've spent a fair bit of time on Lake Ontario this summer - mostly on a paddle board, but have also taken a dip in the lake on really hot days. I've had no issues with the water here and generally don't worry about it, though i do take care not to fall in on the day after a storm especially out by the R.H. Harris treatment plant LOL.
