UBC Apple Festival
"Every year, between 11,500 and 13,500 kilograms (25,000 and 30,000 lbs) of apples are sold to a hungry public. Over 60 varieties of heritage, new and "tried and true" varieties are available, grown both conventionally and organically. These include the heritage apple 'Grimes Golden' and 'Ambrosia', recently discovered in Cawston, British Columbia. Also available for sale are many varieties of apple trees grafted onto dwarfing root stock, perfect for the home garden or patio. New owners of apple trees often attend one of the espalier and pruning demonstrations."

But this could be why you are having trouble finding them:

Canadian Plant Breeders Right 388 - Ambrosia is protected in Canada and in the United States and the propagation and/or sale of the variety is prohibited without the consent of the PICO (okanagan Plant Improvement Company, Box 6000, Summerland, BC, Canada, V0H 1Z0).

So you could write to the company and find out where to buy them
