The only beverage containers refundable in Alberta are containers that have been purchased in Alberta. It can be difficult to tell whether a container has been purchased in Alberta or elsewhere, but there are a few signs to look for. If a container is registered for sale in Alberta it will typically have English and French on the container and the size will be indicated in mL only.
Just because a container says “return for refund where applicable” doesn’t automatically mean it is registered. As well, a UPC (barcode) is not always a must. Some containers that are registered in Alberta don’t have a UPC (barcode) but are still able to be recycled.
