Our Story

Oscar Jin founded JY Construction in 2013. Trained as a violinist before he turned to design and construction, Oscar brings a musician's attention to rhythm, light and detail to every space he plans. JYC began with a small group of experienced interior designers, architects and structural engineers, and has grown into a team of more than 20 professionals. Today we focus on commercial work, especially restaurants, retail and entertainment spaces, for independent owners and national brands alike.

2013 – JY Construction is founded in the Greater Toronto Area.
2024 – Wins Best Commercial Renovation at the GTA RenoMark Awards for the LaunchHub Angels Network Office in Markham.
2026 – Wins Best Commercial Renovation at the GTA RenoMark Awards again, for Greekery Cafe.

What We Do

We are a commercial general contractor first. One JYC team handles architectural and interior design, drawings and building permits, construction and final handover, so you work with a single accountable partner instead of coordinating separate designers, contractors and consultants.

We also offer residential design services.

Our Team

Our team of more than 20 includes project managers, interior designers, an architect and structural engineer, estimators and cost-control specialists. Chief Design Officer Martin Ma has 27 years of interior design experience. Every project is assigned a dedicated project manager, and we run our own woodworking and metalworking shops, so custom millwork and metal features are built to our standards. Meet the team.

Who We Work With

We have built for restaurant, retail and corporate brands including KFC, Burger King, Haidilao Hot Pot, Swiss Chalet, New York Fries, Chatime and Hikvision Canada. We also work inside operating shopping centres for landlords such as CF, Oxford and Ivanhoé Cambridge, where projects must meet strict mall standards, after-hours work windows and high insurance requirements. See our projects.

We have completed projects in shopping centres and commercial properties across Ontario, Quebec, Alberta and British Columbia, including:

Cadillac Fairview (CF): CF Fairview Mall, CF Markville, CF Toronto Eaton Centre, CF Shops at Don Mills, CF Simcoe Place, CF Masonville Place, CF The Station Mall, CF Fairview Pointe Claire, CF Market Mall, CF Richmond Centre
