You can’t just jump in the lake in Toronto
According to the Toronto Port Authority, you can’t swim anywhere in the harbour that has not been designated as a swimming area by the City of Toronto. So, if you’re out on a boat and want to cool off, keep this in mind. Historically, there was also a law that you couldn’t swim in Toronto Harbour in “less than-seemly” attire. Travel writer Mark Stevens pointed out this bylaw allowed police to ticket skinny dippers when the beach at Hanlon’s Point on the Toronto Islands gained popularity as a nude beach. That bylaw has been updated in recent years, and you can now officially swim in the buff if you are at the nude section of the beach.
