Newmarket Water Restrictions 2026

Newmarket's Water Use Bylaw is a permanent year-round mandatory odd/even schedule — not a drought response. The rule applies every day of the year regardless of rainfall, snowpack, or watershed conditions, because York Region's water-conservation framework treats demand reduction as an ongoing operational requirement rather than a seasonal emergency. Newmarket (~90,000 residents) is a town — not a city — by historical preference, having retained town status since incorporation in 1857. The community was founded in 1801 by Quaker settlers from Pennsylvania, and the Quaker Meeting House remains a heritage site. Notable features include historic Main Street Newmarket, which sits within a heritage commercial conservation area; Fairy Lake, the central water feature in heritage Fairy Lake Park; and the Tom Taylor Trail, a multi-use path that runs along the East Holland River. The river bisects the town and has shaped Newmarket's land use and drainage since the 19th century. The town is home to Magna International's global headquarters and Southlake Regional Health Centre, the regional acute-care hospital serving northern York Region. York Region (the upper-tier Regional Municipality) wholesales drinking water to Newmarket and to all eight other member municipalities. The Region buys water primarily from the City of Toronto's Lake Ontario intake at the R.C. Harris Water Treatment Plant and from Peel Region's Lakeview intake, supplementing with regional groundwater wells in northern member municipalities. York Region's Water for Tomorrow conservation programme has driven measurable per-capita water-use reductions and underpins the permanent year-round bylaw. The odd/even rule exists because York Region serves one of the fastest-growing populations in Canada with a finite Lake Ontario wholesale allocation. Spreading demand evenly across odd and even dates reduces peak-hour treatment-plant load and distribution pressure. Newmarket enforces the schedule through its own town bylaw officers; York Region coordinates the conservation framework but does not enforce directly. Newmarket coordinates the same odd/even rule with East Gwillimbury immediately to the north and with Aurora immediately to the south. Cross-border properties along Bathurst Street (the Newmarket–Aurora west boundary) or Green Lane (the Newmarket–East Gwillimbury north boundary) should confirm jurisdiction before contacting an enforcement office — the rule is the same, but the issuing municipality matters.
