How about Social Services? Places like Calgary Immigrant Aid or Language Instruction for Newcomers (LINC) are always looking for people. Give them a call.
I get the idea that a community services organization might be a good fit for what you are looking for. These are some organizations that we work with, that might have some openings, although you would need to check each site to be sure. I know many of the people we hire for similar roles have previous experience in educational backgrounds.
Its not bad job at all. People aren't mean when you're there for a charity and at the end of the day you've done something worthwhile and raised funds that will be used to help run CMHA's programs and services. Another bonus - you can start as soon as your background check clears.
The airport is a good place to work when your in school. I worked as a baggage handler and at airport security while I was going to school.
A co-worker of mine was an escort (security), for YYC at the airport, and it was suuuch a slack job she was able to study and work at the same time.
(escorts basically escorted us to our work site and watched us do our job)
