Hey,
I've been on here many times but never posted.
I applied to Lakehead HBSW back in 2010 when I was graduating from my BA. I applied to both campuses but was only accepted at Orillia. I decided not to go as I had an opportunity to move to the Northwest Territories for work. I emailed Sonya a few weeks after hearing I got in to Orillia to ask for feedback on my application. I highly recommend anyone who didn't get in do this. She gave me a super detailed breakdown of my application and how I scored and where I could improve my application in the future. I think a big thing is experience. I know it is super hard to get experience when working full time but try and think outside of the box.
I spoke with an admissions officer at UVIC in the fall and she told me about a few students accepted in to the MSW without any "social work" experience. They had both worked at summer camps and were able to justify how this experience had helped prepare them for social work. Think into your work history and see if there are any experiencea that you have that you can explain how they relate to social work. I worked on and off as a lifeguard and swim instructor for years and put this on my application when I first applied.
Perhaps take a couple social work classes online over the next year and reapply again next year.
Good luck!
