Canadian Tire already owns SportChek and Mark's, they are already in the clothing space.
I also take issue with the description of Canadian Tire, they are a department store focusing on automotive, tools, home and garden, kitchen, and sporting goods.
Their businesses aren't that drastically different, and it sounds more like they want the brand for a smaller range of goods using HBC stripes.
I mean Canadian Tire is more of a general store.
Hudson Bay started out as a general store and evolved to a more upper class department store. It's way classier or at least it is meant to be but I totally see the link between the two.
Also, Canadian Tire has more than just the Canadian Tire stores now, they own Mark's, Sports Chek, Helly Hansen, Sher-Wood and a couple of other sport related stores in Quebec primarily focused on Hockey, they've been slowly expanding for a couple of years.
Much like HBC, Canadian Tire has a lot of overpriced retail. They don't overlap much beyond kitchenware though.
I guess this gets Canadian Tire into the full department store business like Walmart, Target, or Sears. Now they just need to start selling groceries (again).
I'm not too surprised, but I think CT needs to be careful with how many product categories they have. Earlier this year they sold off the Helly Hanson brand ($1.3bil), so they've got a hole in their portfolio to fill during the 4-year/$2bil restructuring.
