“Where can I swim?”

People use Swim Guide because this basic, reliable, and current information about beach water quality can be really, really hard to come by.

Swim Guide was programmed and designed in-house at Swim Drink Fish (formerly Lake Ontario Waterkeeper), a small non-profit in Toronto, Canada. All of the current water quality data in Swim Guide is updated manually on a daily basis. Our office also supports the spectacular Swim Guide affiliates who have partnered with us in order to make water quality information for their homewaters easy to access.

Since 2011 Lake Ontario Waterkeeper has been working hard to make current beach water quality information easy to access for everyone. Swim Guide exists because we don’t want anyone to get sick from swimming. We want to make it simple for people to find great places to swim and to be aware of the quality of the water at their favourite swimming spots.

We believe people should always be able to access the answer the question, “Can I swim here?”.
