I've seen Interac post jobs that start in September and finish in March. That is two school semesters.

If you qualify for a working holiday visa, you wouldn't need to worry about visa sponsorship. This is because the working holiday visas are granted prior to having a job versus a work visa where you must have a company guaranteeing you work.

I would just keep a watch on the job listings, but the reason less than a year is rare is because most companies and schools prefer continuity against getting someone new and unskilled every few months.
