I was shocked to discover this. I dialed Silks' phone number, and then somebody from Doris Mills picked up the phone. Read the remainder of the blog entry for a brief explanation of who these companies are.
According to what I recall, Phantom created the Silks brand. I assume that companies sell off brands, because those brands are not as profitable as the companies would like. It is kind of sad when a company does that, because it seems like quite a loss for the community. At least the brand stayed in Canada, and is still manufactured by the same company.
Doris Mills also produces a competing Canadian brand, Secret. Both brands are typically found in department stores and supermarkets. Some of their products are higher quality and cost over $10.
