I was homeless several times in my teens the longest was for about a year.

My best advice would be to seek help from social services or their equivalent in canada. Or to call the cops. If all else fails see if you can spend some time with a friend at their hose, explain the situation to their parents. You can also try going to any church and asking for help they may have advice or services that could help you.

Finally if you are over 18 I would suggest getting a tent and camping out. I was able to live about 9 months in the woods with nothing but snares and a sleeping bag until I finally got a job. This would be a last resort though as winter is soon to set in and you don't already have food stocked up. ( had a lot of dried squirrel by winter to help get me through it) If it gets really cold head to a 24 hour store and try to find a place to sleep. Its better then losing toes to frostbite.
