I hope Canadian Tire will carry Knipex the same way they do with Channellock - stable stock levels and occasional discounts. Coupled to store balance rebates, often the prices are better than those in the US.
On a separate note, the lines and products that get dropped are often Stanley Black Decker brands. SBD seems to use Canadian Tire as a testing ground, rolling out new lines of products and discontinuing in a few years. About 10 years ago, Canadian Tire sold Dewalt wrenches with a Proto anti-slip design and shinning chrome plating. Then about five years ago the same wrenches were stamped "Stanley Fatmax" and plated a gunmetal chrome. A year or two later, the same wrenches are stamped Craftsman and were sold in the US - more recognized branding, higher price, and bigger market. Also, some Maximum hand tools have Gearwrench cousins. However, often it seems that Maximum uses obsolete Gearwrench designs.
