FYI if we want to actually compare those places that were mentioned, why not use Walkscore? Comparisons:
2525 Pembina: 58/100
100 Roslyn (as OV as I could think of) : 90/100
846 Westminster (Right smack in the middle of Wolseley) : 86/100

Walkscore is the walkability rating of a neighbourhood.
Let's find a place next to a Costco, just for fun.
Say the one at Kenaston crossing, let's take the nearest dwelling which would be located at 2350 MacGillivray Blvd: 61/100, which is shockingly high for a place which has mediocre transit access at best, but still nowhere near what the walkscore of OV and Wolseley are.
