I don’t know IB that well, but according to the link below, your IB points seem a bit deficient.

You may be able to get into UBC Vancouver’s Arts, or most of UBC Okanagan’s faculties.

Remember that the personal profile may make up for deficient grades. A personal profile is not just about extracurriculars. Life stories and leadership positions do count.
