Newmarket, Ontario

History and Settlement

The area that became Newmarket was originally part of the Toronto Carrying-Place Trail, a portage route between Lake Ontario and Lake Simcoe used by Indigenous peoples. In 1793, Lieutenant Governor John Graves Simcoe travelled this eastern route and subsequently directed the construction of Yonge Street along its path. The first permanent European settlement began in 1801 when Quaker Timothy Rogers led several families from Vermont and Pennsylvania to the area, receiving a land grant of 8,000 acres around the Holland River. Early settlers like Joseph Hill built a mill on the river, creating the mill pond known today as Fairy Lake, and established a tannery and general store. The community, initially known as Upper Yonge Street, grew around these industries and the river.

By 1814, the settlement had several residences and continued to expand. A post office opened in 1826, and for many years the name was spelled as two words: New Market. The town played a notable role in the Rebellions of 1837 to 1838, serving as a centre of discontent against the governing Family Compact. Rebel leader William Lyon Mackenzie delivered a key speech from the veranda of the North American Hotel in Newmarket on August 3, 1837, which helped rally local farmers to his cause. The arrival of the Toronto, Simcoe & Lake Huron Union Railroad in June 1853, the first railway in Upper Canada, was a major event that linked Newmarket to Toronto and spurred further industrial and agricultural trade.

Municipal Growth and 20th-Century Development

Newmarket was incorporated as a village in 1857 with a population of 700, with Donald Sutherland serving as the first reeve. It achieved town status in 1880 under its first mayor, William Cane. The late 19th and early 20th centuries saw continued growth fueled by transportation. The Toronto and York Radial Railway streetcar line arrived in 1899, bringing shoppers to the downtown market, though service ended in the early 1930s. An ambitious but ultimately failed project was the Newmarket Canal, an attempt to create a commercial waterway on the Holland River to bypass rising railway costs. Construction was nearly complete by 1912 when it was cancelled by the federal government. Its remnants are known locally as the Ghost Canal.

For much of the 20th century, development was concentrated along the Davis Drive corridor. A major suburban building boom began in the 1950s, doubling the population from 5,000 to 11,000 by 1970. The formation of the Regional Municipality of York in 1971 expanded Newmarket's boundaries by annexing land from surrounding townships. A significant shift occurred in 1974 with the opening of Upper Canada Mall at Yonge Street and Davis Drive, which began drawing commercial focus westward from the historic Main Street downtown. This led to a period of decline for the old core, which was successfully revitalized through concerted efforts and public investment starting in the late 1980s.

As an Urban Growth Centre under Ontario's Places to Grow Plan, Newmarket has directed future growth to four key areas well-served by transit. These are the Yonge-Davis intersection, Yonge Street south of Green Lane, the area around the Southlake Regional Health Centre, and the Historic Downtown Centre around Main Street. The town's official plan emphasizes controlled intensification and mixed-use development in these nodes, while prohibiting new big-box retail along the Yonge Street corridor. A portion of the town's southwest lies within the protected Oak Ridges Moraine, subject to Greenbelt legislation.
