Celebrating Over 30 Years of Engineering & Manufacturing Leadership
Norstar Windows & Doors Ltd. has stood at the forefront of the architectural fenestration sector across Canada, delivering proven aluminum building envelope solutions for complex architectural demands.
Founded with a definitive commitment to precision engineering and competitive lifecycle value, we grew to become the first window manufacturer in Ontario to achieve ISO 9001 certification. This rigorous quality management framework informs every phase of our operations—from precision profile cutting and thermal-break assembly to structural silicone glazing and turnkey jobsite installation.
Our collaborative delivery model bridges architectural design-assist, project management, and site sequencing. By maintaining direct control over manufacturing tolerances and direct-employed installation crews, we ensure that project managers, structural engineers, and general contractors meet strict building envelope performance criteria with single-source accountability.

Core Standards
Engineered Quality, Built On Integrity
We build long-term relationships with commercial property developers, architects, and institutional general contractors based on quantifiable performance metrics and operational transparency.
Certified Quality & Compliance
Our manufacturing protocols align with rigorous international quality standards. ISO 9001 certified QA checks guarantee structural integrity, weather sealing, and dimensional precision across all manufactured components.
Engineering & Design Assist
We work collaboratively with project architects and structural consultants during pre-construction to analyze wind load resistance, seismic movement, thermal transmittance, and critical water-shedding interfaces.
Single-Source Delivery Model
By controlling both factory fabrication and on-site glazing installation, we eliminate trade interface disputes, streamline construction milestones, and provide a single accountable warranty package.
