The prairies generally and the chinook belt of Alberta specifically have always been a tough place to grow fruit. Thankfully, plant breeders have been working on this problem for over 100 years and their and many nursery people's efforts have yielded good results.
One of the strongest supporters and tireless workers in this field has been the University of Saskatchewan. Their agricultural research into prairie fruit production is a decades old program. For plenty of good information see www.fruit.usask.ca.
There are many, many apples and fruit varieties sold, some good, some not. As with all Trees in this area the test of time is indisputable. Like the latest fashion varieties drifting along the cat walk, many will never be seen again. If you find an apple or fruit variety you like, please do a little reading; you will save yourself a lot of trouble.
