Is there a place where I stay for CDN300 a month in any part of Ontario ?

you can rent a room in a house for that (in smaller cities) Kitchener, Waterloo, Guelph, Kingston)

You can rent a room in a rural community for 300

it's not going get you anything in a major urban centre (Ottawa, London, Hamilton, Toronto)

depends on when too ... in the summer, you could sublet a student rental for $300 ... there are options ... if you are not picky

I don't think so. It usually costs more than that to rent just a room in a house.

Good luck. Now, a room for $400 could be found, but not easily.

IS that just a room, or are you expecting to eat on that amount? If so, no, not happening.

Not going to happen.
