The mall entrance near the former Dominion (Food Basics) is fenced off. The mall entrance near the former Woolco anchor is unusable due to construction, and the anchor is no longer physically connected to what's left of the wall. That leaves the centre mall entrance (to the left of the Hock Shop) and even that's locked at 6pm on a Saturday. There might be one or two businesses max, excluding outparcels and whatever faces directly on to the carpark. I've removed a bunch of these, but they (if the business has moved and not simply closed) do still need to be re-created in their new locations.

This is what I've been able to find for individual businesses formerly at 1300 Bath Rd (aka 300 Bath Rd W in the former Township of Kingston):
