The GTA Signature Series
We just re-invented the window.
Stronger. Brighter. More Energy Efficient.
Our solid-core Signature Series window is built with microcellular PVC (mPVC) containing billions of microscopic cells. That gives the frame a stronger structure and guarantees better efficiency — engineered for the Canadian climate.
Now available in Triple-Pane.
A tree planted for every window we make.

Here's what your neighbours are saying
With GTA Windows and Doors you can expect superior products, expert installation, and genuine service. Backed by thousands of installations across your community — don't just take our word for it.
The team was brilliant. As a first-time window buyer, my sales rep was articulate, friendly, knowledgeable, and made such an important purchase comforting. These windows saved my life over the winter. I highly recommend GTA Windows and Doors to anybody considering upgrading.
The installers did a very neat and clean job — they came on time, finished the work, removed all the debris, and vacuumed the work area. I am very pleased with their work and the product!
I would recommend GTA Windows and Doors 100%. Great experience from start to finish. Had two sliding patio doors installed. Knowledgeable, helpful, friendly rep, and a fantastic installation crew — on time, courteous, professional, and tidy. The doors look amazing.
The crew showed up on time and worked hard to get the windows done by the end of the day — amazing job! Everything was cleaned up when they left. The windows look amazing and I feel the temperature difference already. Very professional!
We got three other quotes before reaching out. The rep was professional and friendly, took her time to explain everything clearly, and helped us choose the right option. The noise reduction is great plus we keep our thermostat two degrees lower now.
My home is a custom-built house and the front door was not easy to fit, but the team made sure I was satisfied. The trim work around the door and transom was matched to the rest of my home. Well done and thanks.
