We have found Canadian Appliances to be the most cost effective retailer of any in the GTA for appliances, and in the most recent case, purchased a Samsung fridge which was $500 cheaper than 4 other stores we visited.
Further, I highly recommend their sales consultant George Moutoulas as he was responsive and gave us a no nonsense quote. No haggling was necessary given how good the price was, and in view of our time constraint in replacing the fridge, it was very much appreciated.
A year previous, we had also bought a Samsung washer and again, Canadian Appliances had the best price.
