My favourite cookies are most often called Sultana Biscuits.

In Vancouver you can find them in speciality Asian food stores.

Superstore no longer stocks them. Walmart no longer stocks them.

Update. Superstore in Calgary had them in the foreign food speciality aisle December 2018. 

You can buy Sultanas online from Amazon.com. But not Amazon.ca.

Waitrose in the U.K. sells exactly the same thing calling them garibaldi biscuits.

Tesco U.K., the third-largest retailer in the world measured by gross revenues, also sells garibaldi biscuits.
