Being Canadian designed and built, I have to assume these attributes make it an undesirable venture by mainstream model companies. So Hobbycraft is your only option for 1/48. Assuming you have tried ebay, try searching online Canadian hobby shops. If you do any traveling, popping into a department store might surprise you. I recall seeing one in a small town hardware store of all places.
Here's an online shop to get you started:

You will be probably looking at independent shops where you have to contact them first for availability and ordering.
