Call me crazy but 2 hour free parking might be worth a look at for both City Centre and Ice District parkades.
The problem with parkades is that they have overhead operating costs in the evenings. Manulife makes it work on event nights for Rogers, knowing people will park there and pay, which pays for the parking attendant, which is now mandatory due to the security issues downtown. If you make it free, there are still costs associated—do you pass that onto tenants in their leases?
The other issue is that there is basically no point in coming to the mall downtown anymore for the surrounding inner communities. It is faster to drive somewhere else with amenities and not worry about your car being broken into as much as downtown, even in a parkade. It wasn't that long ago that I went downtown on a weekend to the mall to Softmoc to buy a pair of shoes that I didn't want to drive to SEC/Southgate for. That option is gone now.
The retailers making it work downtown aren't the ones that are worried about free parking - Henry Singer, Helm, and other specialty clothing. Likewise, no one is driving downtown to go to Tims or the Telus kiosk, even if there is free parking. The downfall has been gradual, but the gap is so bad now that it is a monumental task to rebuild retail to the point where it is
just acceptable for the average person who wants to visit Gap, Sporting Life, Banana Republic (insert other basic national retailers here).
Is free parking enough to attract those tenants? I doubt it, to be honest. The foot traffic from office spillover was the main driver of traffic for them, and that is never coming back. Realistically, it is going to take a slow, gradual decade or two for downtown to get back to a good spot, and it is not going to look like it used to.
