Nazi toy soldiers/flags on sale in Ottawa...

At Byward News in the market in Ottawa, a newstand sells a variety of toy soliders. One of their current displays is one of Nazi soldiers, Nazi flags, and a variety of marching Nazis. They have a small sign that says how reprehensible the Nazis were....but is this Kosher? Clearly they have the right to sell what they want...but I think this is particularly unsettling; and yes, this was on display during Remembrance Day weekend.
