St. Lawrence Market North, Public market hall in Toronto, Canada.

St. Lawrence Market North is a five-storey market building on Front Street, connected to St. Lawrence Hall. Its ground floor covers 4,000 square metres, with a central atrium rising through the floors above, which hold 4,000 square metres of office space and 3,000 square metres for courts. An underground garage has 250 parking spaces. The design is by Rogers Stirk Harbour + Partners with Adamson Associates.

A market has operated at King and Jarvis since Lieutenant-Governor Peter Hunter designated the area the Market Block in 1803. The first permanent farmers' market went up soon after; a brick replacement followed in 1831, housing City Council from 1834 to 1845. The 1968 north building was demolished in 2016, and the current structure opened with a grand ceremony on May 10, 2025.

The Saturday Farmers' Market, the largest in Toronto, opens at 5 am. A Sunday Variety Market and a New Antique Market now occupy the Sunday slot after the original antique market moved to Mississauga in 2022. From mid-November to December 24, Christmas trees and holiday greenery are sold daily.

The building has several entrances and clear pathways connecting the different levels, so finding your way around is straightforward. From mid-November onward, the space gets noticeably busier as seasonal goods become available, so a weekday visit may be more comfortable during that period.

During construction work on the site, workers found nineteenth-century remains buried beneath the building, including fragments of old sewers, metal tools, and broken ceramics. These objects suggest that the ground beneath the current market holds a record of Toronto's daily life from well before the city took its modern shape.
