⚠️ Important Notice: Temporary Shipping Delays on 509 Canada Products
Due to the closure of the previous 509 Canada distributor, there is currently a significant delay in obtaining items that are not in our in-store stock.
We are in a transitional period as 509 products move to a new distributor, and this process is nearing completion — however, the new distributor has not yet confirmed exact inventory availability.
If an item is listed as “Out of Stock” or “Backordered,” please be aware that this delay will apply.
✅ If we have the item in stock, your order will ship as usual.
We appreciate your patience and understanding during this transition.
