Who We Are

About Four Seasons

An Ontario heavy civil contractor delivering public infrastructure across the Greater Toronto and Hamilton Area since 2003. Self-performing, COR certified, and headquartered in Brampton.

Four Seasons Site Development Ltd. was founded in 2003 to deliver heavy civil infrastructure for the public sector. Twenty-three years later the company employs more than 120 full-time staff, operates company-owned asphalt plants, and self-performs the principal trades on every contract.

The business has remained focused on a defined scope of work. Road reconstruction, underground servicing, transit and rail infrastructure, bridge and structural work, streetscaping, and resurfacing and earthworks make up the six core disciplines. Each is supported by dedicated in-house crews, equipment, and supervisory staff.

Clients are exclusively public sector. Regional governments, municipalities, transit agencies, and public health authorities across the GTHA award and administer the company's contracts. The result is a contractor whose work product is publicly visible and whose project list is independently verifiable.

Company History

Two Decades of Heavy Civil Work

Founded in 2003 in Brampton, Four Seasons started as a small site development contractor working on local municipal contracts. The early focus on roadway and underground servicing established the trade base that the company carries forward today.

Metrolinx contract work began in 2005. The corridor experience built over the subsequent two decades on PRESTO Fare Card Infrastructure, Oshawa GO Station, the Barrie Two-Way All Day Infrastructure Improvements program, and the active Heritage Road Layover has established Four Seasons as a recurring contractor on transit and rail infrastructure.

Self-performance capability has expanded continuously. Two complete asphalt paving crews, three excavation and grading crews, one dedicated concrete crew, dedicated sewer and watermain crews, and three streetscaping and restoration crews now operate within the company. Company-owned asphalt plants supply the paving operations.

The contractor has been recognized through industry awards including the 2025 OPWA Historical Restoration and Preservation Award and Project of the Year for the Belfountain project, the 2022 OPWA Transportation Award for Clark Avenue, the 2022 OPWA Structures Award for the Major Mackenzie Watermain, and listings in Growth 500 in 2017 and 2018, Profit 200 in 2010, and as a Regional Runner-Up in Canada's 50 Best Managed Companies.

How We Work

Operating Principles

Self-Perform the Work

Excavation, paving, concrete, sewer and watermain, and streetscaping crews operate inside the company. Schedule certainty and quality control follow from direct trade control rather than coordination across subcontractors.

Specialize in Public Infrastructure

The company has never pursued private development work. The standards, contract administration framework, and procurement processes of the public sector define how Four Seasons operates.

Maintain Direct Equipment Ownership

Equipment fleet sized to the work the company tenders. Asphalt plants under direct ownership. Reduced dependency on rental, supplier scheduling, and third-party material sourcing.

Build Long-Term Client Relationships

Repeat work for the regional governments, transit agencies, and municipalities that originally awarded contracts to Four Seasons. The same project managers, superintendents, and trade crews return to clients across contract cycles.
