To apply for a mortgage in Canada, you will need to provide specific documents to confirm your identity, income, and financial status. These include government-issued identification, SIN number, and proof of income such as pay stubs, T1 General Tax Form, NOA, T4 or T4A tax forms, and a letter of employment. You will also need to provide basic financial information such as your credit score, pre-approval letter, and bank statement. In addition, you will need to confirm your down payment and provide details about the property you intend to purchase. Providing these documents will help your mortgage broker determine your eligibility and find the right mortgage product for your needs.
