There isn't a major shopping centre officially named "Westmall Toronto." You're likely referring to Westdale Mall, often colloquially known as "The West Mall," located in Etobicoke. To get the most accurate and up-to-date store list, it's always best to check the mall's official website directly, as store openings and closures can happen frequently.
You can typically find a full directory on the mall's official site under sections like "Store Directory," "Shops," or "Retailers." This will provide details on specific stores, their locations within the mall, and sometimes even their operating hours and contact information.
Pro tip: If you're looking for a specific type of store (e.g., clothing, electronics, grocery), use the search or filter options on the mall's website if available. This saves time scrolling through the entire list.
