I cannot show you live location data or real-time store listings — that requires your actual GPS coordinates and access to current business databases. But I can point you to the best tools that DO have this, and explain what you actually need depending on what you are shopping for.
Before you drive out, answer this: Are you looking for a specific store, or browsing? If you need one specific brand, call ahead or check their website for nearest location — do not assume every mall has every store. If you are browsing, check the mall's website first — it lists all tenants so you know if it is worth the trip.
Pro tip: Most Canadian shopping centers post their hours online and updated during holidays. Search '[mall name] hours' rather than driving there and finding it closed. If you want the full tenant list before you go, almost every major mall in Canada now has a mobile app — download it and you can see what is actually there, parking availability, and current sales.
