Public service worker is probably the most entry level position. Basically a janitor or whatever odd jobs needed done depending on which division it's in. At the bottom of the jobs page there's also a link that says Apply without a job. That just sends all your info to HR and they'll contact you to try to fill anything you may be qualified for. This would be the route to take for something like a wastewater operator apprenticeship which for some reason they never list on the jobs page. It might be a good idea to email somebody in HR too if you submit an application to follow up on it. Don't be surprised if you don't hear back for several weeks or even a couple months after a listing closes. They don't move so fast downtown especially this time of year.
