Auto-financing for low income person?

I’m a person aged around mid-twenties, living in Canada. I want to purchase a used or second hand car ranged around at
$ 7000- $ 10,000, but my salary is only 8 per hour. Is it possible for me to get car loan from bank.
I don’t have any expenses like rent as I live at my family home neither do I have any student loan to be paid.

How much downpayment would I have to make and will there be other costs while buying a car.

Also, I wanna know how to check a credit score. I usually pay my credit card bill on time..does it mean I have a good credit score?

Please help.
Thanks
