If they just lost Nordstrom they are not doing okay.
In the case of Yorkdale when Sears went belly up it was replaced by a large Restoration Hardware store. Nordstrom only had a handful of stores in Canada and for whatever market reasons they closed them all. Not sure what will replace Nordstrom since its too soon since they closed. Time will tell as always. A while ago there was only a Tesla store but two more EV sellers have joined the mall now. A Microsoft store set up to compete with Apple has also bitten the dust in recent times. If the malls are hurting I don’t see it even with Nordstrom gone.
