Good to know

Where do these student & summer jobs come from?

Every posting is read straight from the employer’s own careers page or a government job site - cities and towns, health authorities, school divisions, utilities, stores and more. No reposts, no recruiters in the middle. You apply on the employer’s site.

Why 60 km?

St. Catharines is a smaller community, so we include jobs within a 60 km drive - most people outside the big cities commute that far.

Can I see which jobs I’d actually get?

Yes - add your resume (or your LinkedIn PDF, or just type your past jobs) and every job gets a match score with the reasons. It’s read on your device; nothing is uploaded unless you sign in and choose to keep it.
