UofA doesn't place a huge emphasis on GPA. I would say it would be important to look at your references and your statement of intent. Those are what set you apart from other students, even if you have an impressive resume and 4th quartile scores. From what I've heard, references and the statement is what UofA weighs heaviest.
UofA ESPECIALLY wants to see EDI (equity, diversity and inclusion) directly embedded into quite literally everything you submit to them. If you're applying again, I would recommend adding more EDI into your application. I've heard that often, really strong applicants may not get accepted due to this. Honestly I think they care more about what you say and have experience with related to EDI over your GPA. (Other schools in Canada are different though, this is just my understanding of the UofA)
