Part of a network of small peninsulas stretching out into Lake Ontario, Humber Bay Park West is a beautiful spot on the city's waterfront. The rocky beach is a very popular scuba diving site, especially with beginners. Trails behind the beach make for a good walking and bicycle route. This side of Humber Park is home to a few boating clubs and docks, which means it has slightly less green space than its Eastern counterpart.

Although a variety of recreational activities takes place in the water here, water quality at Humber Bay Park is currently unmonitored by the City of Toronto. Water quality concerns at this site are tied to its close proximity to the Humber Wastewater Treatment Plant. Information and results of E. Coli sampling will be posted here until the last week of September 2020. After this period, recreational water users are advised to be cautious as E. coli bacteria can cause health problems in humans and pets.

A small group of trained citizen scientists is undertaking weekly sampling on Thursdays. Results are posted to the Swim Guide on Friday afternoons. These citizen scientists are a part of the Toronto Monitoring Hub, which is one of Swim Drink Fish’s monitoring hubs.

You can access the detailed open data files for this location from the Lake Ontario Waterkeeper Toronto Monitoring Hub.
