Anecdotal stories about taking stuff home on the subway or never having driven to the Eaton Centre aside, I agree that the Eaton Centre is probably far less reliant on automobile traffic than any other major mall in the GTA. Having said that, I used to work in one of the towers at the Eaton Centre, and that lot was often packed - even level 5. Obviously, it serves two of the three office towers (I presume that the workers at 1 Dundas who commute by car use the Dundas parkade), and I suspect that it would hard for CF to lease that office space without any parking. The lot is even busy evenings and weekends - lots of shoppers do appear to drive to the mall. You also see a lot of people parking there for church on Sundays (St. Michael's, Metropolitan United, Holy Trinity), as well in the evening for shows at the Canon, Massey Hall and the Elgin Winter Garden. If it was more lucrative to replace the parkade with retail or office space, it presumably would have been done by now. I suspect that the lot is a cash cow.
