Proudly Made in Canada

We proudly make each door and window we sell right here in Canada, in the communities that have supported our business from day one. At North Shield, we know that our customers and communities are what makes our business possible and are dedicated to keeping our manufacturing local and employing quality craft persons from within our own area.

Energy Saving Designs

When we set out to craft our windows and doors, we knew we didn’t just want to make beautiful products, we wanted to make products that would save our customers money and be good to the environment too.

This is why we employ multiple energy-saving materials and construction methods in all of our products, including premium insulation and LoĒ-180 glass which deflects heat in the summer and reflects it back into your home during the winter.

We also strive to reduce waste in our crafting and installation process and make it easier by removing and disposing of old windows and doors.

Easy Installation and Estimates

We offer free estimates to all of our Greater Toronto Area and Winnipeg customers to ensure our customers get exactly what they want with no hidden costs ever. Our installation process is also tailored to your schedule whenever possible and we strive to give you detailed, accurate timelines with a 100% satisfaction guarantee.
