Outstanding

Why buy breakers from a box store when they are always cheaper here? The customer service is very responsive and helpful and the shipping is free if you buy a couple. I will be sending my friends here for sure.

Great customer service.

Even after holding an order for 3 months to find out it was the wrong parts, David allowed me to return the wrong part and did his best to try and find the correct part for my application.

It was an amazing online shopping experience with fast shipping and excellent customer service.

Totally recommend for sourcing breakers which are not stocked at any of the big-box home improvement stores.

Very user friendly

I ordered a few items from Canada Breakers and the items shipped and arrived promptly. Their website is clean and very user friendly. I had some questions about my order and their customer service was outstanding. I will definitely be using Canada Breakers for my next order.
