It'll depend on the university of course, but I wouldn't worry to much as long as your overall grades are acceptable (and from the sounds of things, they're acceptable enough. Not super amazing, but as long as you're not hunting for one of the top end high competition schools, I wouldn't be too concerned).
First year math in my experiances dosen't presume you know much of anything going in due to the variety of different high school math curriculums, and so they end up teaching you most of the math you'd need from scratch anyway. As such I would imagine most universitys don't look at your math mark and go 'Hum, they're not good enough at math. Denied.', but rather 'Looks like they've got decentish marks so they must be a hard worker, and they did take math. Accepted.'. Specific programs, particularly in the more prestigeous universities may look closer and only accept a minimum mark in math, but I would imagine you could find out by contacting the appropriate school/browsing their site.
