About Torwin


At Torwin Windows and Doors, our goal is to become the last window and door supplier you’ll ever need! That’s why we tackle each job as a team, and always put our customers first. We do not offer a “cookie-cutter” approach. We treat every home as its own unique project.

As a proud winner of HomeStar’s “Best of 2020” Award, we know that no two customers, and no two homes, are ever the same. With that in mind, we use a custom approach from concept to construction on every window and door replacement that we install. Our in-house design team works with you at each step to conceptualize your vision from start to finish. And all our installations are completed by our expert team of in-house carpenters.

We really mean it when we say we want to be the last window and door supplier you’ll ever want to work with. That’s why the Torwin Touch doesn’t end with installation! Unlike other window & door manufacturers, we offer a LIFETIME warranty on all windows.


How did we become one of the top window and door companies in Toronto? It’s simple!

From our humble beginnings, Torwin has grown and flourished as our owners recognized a gap in the replacement windows and doors market.

They saw a need for specialized products, skilled carpentry, and quality finishing details. Torwin fills this demand for a customized approach to window and door replacement. Consider us your one-stop-shop for designer doors and quality windows.

At Torwin, we take great pride in our quality, craftsmanship, and exceptional customer service. This has kept our business growing in the same location it was originally founded for over 30 years. We invite you to visit our showroom, meet us, and get a first-hand look at what Torwin can bring to your window and door replacement project!


Custom work is our speciality! In fact, every window and door we make is custom made for your home. Everything is made to order, and we do not offer “stock” sizing. This allows us to make windows and doors that are custom-fit to each and every unique home.

Our highly skilled team is able to tackle custom work including bay, bow, and greenhouse windows with custom aluminum capping, profile capping, and raised panel capping. We offer bullnose sills (aprons), wood mullions in between the joints and the window, as well as casings that are wider than the competition and have a backband.

We also offer custom arched windows and trim in all one piece, in a wide variety of wood species ideal for either staining or painting.

What’s more, our team can handle knockouts! Where most window and door companies hire a General Contractor, we have the skills needed! Whether you’re looking to knock out a window to make it a door or make it a wider window or putting a window or door where one does not exist, we can make the dream a reality. We can knock out concrete, double brick, brick veneer or siding and finish it completely from the inside out!


Ever since we first opened our doors in 1988, Torwin has always been family owned and operated. Founded by the husband-and-wife team of Jody and Ivana Crevier, Torwin understands that there is more to windows and doors than a monetary transaction between customer and company.

From the beginning, we set out to create a company that would offer a more personal, custom touch. A company that allowed each customer a wider variety of options. We wanted to be something different from all the big box stores and large manufacturers of windows and doors:

A business that cares deeply about its customers, their homes, and their families.

When you walk into Torwin, you will see us, Jody and Ivana, around the office. You can meet us, shake our hands – something that is becoming harder to find in this industry. We have families and a home of our own. And we have first-hand experience, and understanding, of the level of care that goes into the buying and installing of new windows or doors.

Jody, Ivana, and the entire Torwin Team take pride in our business. And having the opportunity to give back to the community that has been so gracious to us is important to everyone here at Torwin. That’s why we make regular donations to Habitat for Humanity, the Canadian Cancer Society, and various organized sports teams throughout York, Halton, and Durham Region.
