Actually that is a US only brand. They don’t sell it here. Few Canadians are aware of its existence.
I had forgotten that.
My dad and his pals in North Dakota seemed to prefer Windsor to other whiskeys and bourbons so I was familiar with the brand.
Later when I bartended in Minnesota, south of Winnipeg, we had lots of Canadian customers. If I recall correctly some would order a “blend,” and we would then serve them Windsor or Canadian Mist, for the very reason you mention.
