Client Feedback

I am artist on west coast of the USA  so why would I go to the expense of having stretchers shipped from Canada? Because Upper Canada Stretchers provides a superior product with high reliability in both customer service and product consistency.

- Claudia Pettis,

I want to thank you again for the outstanding work that Upper Canada Stretchers did for me.

When I needed a very large stretched canvas for a public commission, I wanted to make sure that it was professionally assembled and stretched so that it could be painted on, moved easily, and hung perfectly without worrying about warping or unevenness. The frame is strong and square yet light enough that it allowed me to work on it in two different locations and the canvas was stretched so neatly that the surface was tight and even, and all the edges are clean and smooth.

Both my client and the professional curator who hung the piece in its public location liked my work but were also impressed by the quality of the stretched canvas.
