While you are renting as a student, most landlords will require you to have a guarantor. A guarantor, sometimes called a co-signer, who is someone with a Canadian bank account who agrees to pay your rent in case you cannot or in case you leave the city or country. For many students, this is a working parent or older sibling, but extended family and friends can also be guarantors.
If you are a mature student, graduate student, or work a steady part-time or full-time job, landlords may not require you to have a guarantor.
If you do not have a guarantor, you may wish to have letters from employers, scholarships, and other forms of income and/or a bank statement that demonstrates you have enough money to pay the rent for a few months.
