Could I be hired in advance?

I have an interview in a week and a half for a job in Montreal. I'm currently in Toronto and I have one more course to finish up in the summer before I graduate. I won't be able to start said job position until August at the earliest.

I was wondering would this affect me being hired because I won't be able to start for another three months? I really want this job and I am more than willing to travel to Montreal in between my classes if they need to do a second interview or have me go over some things. It's just that I'm in a pickle because of my last course and I cannot start full-time until August.
