I haven't been to that u-pick farm, but I'd love to hear your thoughts on it if you do go. I am planning to go pick saskatoons this weekend or next, so I've done some research about places around Calgary. As a sidenote, here are other u-pick farms with saskatoons (based on info from http://www.albertafarmfresh.com):
