The Toronto Hub Results
The Toronto Hub and the City of Toronto follow the pre-2018 standards set by Ontario’s 2014 Provincial Water Quality Objectives, established by the Ministry of Environment, Conservation and Parks. The pre-2018 Ontario recreational water quality standard states that a site fails to meet recreational water quality guidelines if the geometric mean (minimum of five samples) exceeds ≤ 100 E. coli/100 mL. Below you will see the E.coli results for each sample we take, the geomean of those samples, and if the site passed or failed based on this standard for the most recent results. If our sampling season has concluded you will see the historical status of the site and its pass rate for the most reason year.
