We have a kosher cafe in the JCC on 90th ave SW. It is not cholov yisroel or bishul yisroel, but is certified by the ABK, an offshoot of the BCK. You can buy many Kosher products from Sobeys in Bridlewood:
1607 90 Ave SW, Calgary, AB T2V 4V7
They carry Heimishe products, cholov yisroel, meats, etc. and ave a pretty decent selection. It is a 15 minute drive from the Jewish community.
Superstore just off McLoed Trail also carries some meat, depending on whether or not they are in stock.
The Carriage House bakery carries the same Kosher certification as Karen's.
