Yeah, Indeed can be hit-or-miss for temp jobs. I’d recommend going through https://jobssite.ca/job-agency-mississauga/ job agency mississauga. They have a section specifically for temporary and seasonal positions. I applied through them last summer and was placed in a call center job for three months. It wasn’t glamorous, but it paid well and filled the gap. The cool thing was they kept me updated every step of the way and even offered me another gig after that one ended. You might want to register with them ASAP since summer positions get filled quickly.
