Where did you get the "in Canada" from?
I read the article and all the closings were in Texas and owned by a single franchisee, "The Lonestar Project".
From reading other sources after a quick google I learned that Dairy Queen Head Office threatened the franchise owner with termination if they did not remodel and bring their restaurants up to date. The franchisee refused to, so DQ terminated some of their franchises and stopped shipping food and supplies to the remaining outlets.
Around 37 Dairy Queen locations around Texas have closed since February, as a legal battle between the corporation and a franchise owner drags on.
