Ah, OK, I see. No, I don't have experience with anything like that. I want to hear from people who worked on survival jobs. I need to have a better idea on what I can do, and what to expect. Will they ask for my SIN for survival jobs?
Low skill jobs as other pointed out are big box store job to stock shelves, fast chain restaurants that provide some basic training, general labour on construction sites (you don't need skill but you need to handle physical work and some needs to be outside in the cold).
All of them needs SIN. If you don't have a valid work permit or a valid status to work in Canada, it's not going to be easy to find any job. And it will impact your application to become a PR or getting other visa in Canada.
Assuming you have valid SIN, one possibility is to look for survival jobs at places that you already visited the last few months. (restaurant, store, services) Some of the people who work there may already recognize you as a customer and they may let you join them.
