I have a BSW myself from the prairies & I'm also looking at applying for UofT or UBC (Vancouver not Okanagan) for 2021! Like you I can't seem to find much about UBC on these forums, as most active users seem to be from Ontario.
I found this post about UBC's faculty of social work (albeit from a BSW graduate, so it may not speak to the MSW program), which doesn't seem very optimistic... Hopefully the highlighted issues are mainly for their 2-year MSW program (which has suspended admissions for a few years now) & not for the advanced standing. Have a look:
I believe CASWE provided UBC's MSW program with partial accreditation for 4 years from 2017 to June 30, 2021 to fix some of the issues. The accreditation report should be available online (https://academic.ubc.ca/sites/vpa.ubc.ca/files/documents/Report on External Reviews 2017-18 - final2.pdf) & highlight what areas were lacking in the 2017 review. The good thing is that UBC's MSW will be going thru re-accreditation during the spring of 2021, so hopefully that will provide some peace of mind + highlight what has been done in the past 4 years to improve the MSW program. UBC's MSW tuition is also significantly (40-45%) cheaper than UofT, though there is much less financial support (scholarships, etc.) available. I think this is due to their small faculty size (12-14) & them admitting only about 50 advanced standing students each year. They definitely aren't a huge program when compared with a program like UofT's (I heard they admit up to 250 each year for their 2-year + adv standing). However, in a big city like the Vancouver area, a small program likely means there is less competition for practicums + finding work after graduation.
Has anyone else heard anything about UBC's MSW program? Good luck on everyone's applications!
