Water Safety

The Ganaraska Region Conservation Authority is further extending the Shoreline Conditions Statement due to persistent high-water levels on Lake Ontario. The water level of Lake Ontario has remained stable over the past three weeks and is currently 75.41 meters above sea level (masl). Persistent precipitation this spring caused Lake Ontario water levels to increase to 75.30 m by the end of April 2026, and 75.40 m by the end of May, an increase of 86 cm since the start of March. The average water level in Lake Ontario rose 42 cm over the month of April, compared to the long-term average April rise of 21 cm.
Since 1960, Lake Ontario has statistically reached at or above 75.30 m once every three years, or 33% of the years within the period of record. Although significant, reaching a water level of 75.30 m is not unusual. This Shoreline Conditions Statement for the Lake Ontario shoreline, within the Ganaraska Region, will be in effect until Friday, July 31st, 2026, at 12 p.m. Conservation Authority staff will continue to monitor conditions and provide updates as necessary.
