Gormley is a hamlet in York Region, Ontario, Canada that overlaps parts of Richmond Hill, and Whitchurch–Stouffville, two municipalities within the Greater Toronto Area.
It was divided into two parts due to the construction of Highway 404. A portion of Gormley situated within Richmond Hill's political boundaries is subject to "Heritage Conservation District" controls.
The community was named after its first postmaster, James Gormley, who served from 1851 to 1876.
The hamlet originally straddled the townships of Markham to the south and Whitchurch to the north, both in the County of York.
A future challenge to the community of Gormley is the proposed development of an international airport immediately south-east of Whitchurch–Stouffville (the Pickering Airport lands). Under the current plan, the approach for one of the three landing strips would be directly over Gormley, with planes descending above the hamlet from an elevation of 521 metres to 480 metres.
The plan anticipates 11.9 million passengers per year (or 32,600 per day) by 2032.
