Salary progression in Canada

So I'm going to be starting my first job out of school in a MCOL area in Ontario this fall. It is a small public firm and I'll be starting at $48K + 1.5x OT.

I was happy to land anything in this economy but as a career changer in my 30s I'm concerned about how long it might take me to increase my comp to a reasonable level.

Can I expect 80k when I get my letters (3-4 years)? Will I need to hop to a bigger firm? What's a typical trajectory for a reasonably motivated and ambitious accountant these days?
