As per the faculty FAQ:
"Do you give preference to students from specific universities/colleges?In the selection of applicants, preference is given to well-qualified residents of BC who are Canadian citizens or permanent residents of Canada. Special consideration may be given to Aboriginal applicants and applicants from under-represented areas of BC.(http://www.calendar.ubc.ca/vancouver/index.cfm?tree=12,213,956,1563). Preference is not given to applicants based on their specific universities/colleges. "
Just do your best if you happen to get an interview, don't really know what a 3.6 equates to but it all depends on the applicant pool each year.
