When the level of bacteria is high enough to cause illness, staff from York Region Health Services Department will post a sign(s) at the beach to warn swimmers of unsafe conditions.
- A red sign is posted when the bacteria level is more than the Ministry of Health standard.
- A blue sign is posted when the bacteria level is within acceptable limits.
Beaches will remain closed when there are indications of hazardous or infectious materials present in the water, or in the event of a blue-green algae bloom. When the water is once again safe for swimming, the beach will be reopened.
