My sales rep Stan was great and pricing was very fair
Mike and the install team worked hard and did a great job
Would recommend Canadian choice windows and doors to everyone!

We had a good experience working with Tony from Canadian Choice Windows and Doors. He carefully walked us through the process, and even where there were hiccups along the way, he helped resolve the issues and made sure the work was done to our satisfaction. We believe he has his clients’ best interest in mind in all that he does.
I.e some of the trim we wanted was not available but he provided various options that match our needs. Also after the project installation was completed and the snow melted we requested a clean up the patio area.
7 windows replaced various types and sizes

Windows And Doors
The service was fantastic from start to finish !from booking to getting my windows install . Stan abs Harry abs their team were great !
Outstanding!
Our home is approximately 20 years old, however the existing windows had numerous problems which led us to Canadian Choice Windows and Doors. From the get go they were responsive and professional. Stan helped guide us through the decision making process and financing options with ease. He really understood what we wanted and helped us make a very big decision, seem simple.
The window installation was scheduled on-time. Slava and Max are hands down the best installers! On time, worked fast and clean. They had the challenging task of adding a net new window, in extremely cold temperatures. This caused some delays but they communicated very effectively as to why and when they would return. There were only minor delays but well worth it; the final product is gorgeous!
Overall this was a great experience and I would recommend them.
