March 9, 2026 | Posted by: Patricia McKean - Cochrane and Airdrie Mortgage Broker

When clients in Calgary, Airdrie, Cochrane, or Rocky View County start a mortgage application, one of the first questions we hear is simple: “What documents do you need from us?”

Our team walks people through this every day, and the truth is that most delays in mortgage approvals come down to missing or incomplete paperwork. The good news is that once you know exactly what lenders expect, it becomes straightforward to prepare everything ahead of time.

If you're feeling unsure about what’s required, you’re not alone. Many first-time buyers and even experienced homeowners are surprised by how specific lenders need documents to be.

Below is a practical checklist we use with our own clients across Alberta.

Documents Needed If You Are Employed

If you earn income from an employer, lenders need to verify your employment, your income stability, and your tax history.

Employment verification

You will need a job letter that includes:

• Start date
• Job position or title
• Income or hourly wage
• Whether the role is full-time or part-time
• Employer contact details

Lenders use this to confirm the income you’re qualifying with is stable and ongoing.

Recent pay stub

A current pay stub helps confirm:

• Current earnings
• Year-to-date income
• Payroll deductions

Two pieces of identification

Typical examples include:

• Driver’s licence
• Passport
• Permanent resident card

Last 2 years of Notice of Assessment

Your CRA Notice of Assessment confirms:

• Your reported income
• If you owe taxes
• Whether you are up to date with CRA

T1 Generals if you earn overtime or commission

If your income includes commission, bonuses, or overtime, lenders usually require:

• Last 2 years of T1 Generals
• T4 and T5 slips

Documents Needed If You Are Self-Employed

Self-employed mortgages require a deeper look at income because lenders need to understand both personal and business earnings.

Most lenders request:

• Last 2 years of T1 Generals with T4s and T5s
• Last 2 years of Notices of Assessment
• Last 2 years of business financial statements
• Two pieces of ID

Many lenders average the last two years of income to determine qualifying income.

Down Payment Verification

When you write an offer on a home, lenders must verify where the down payment funds are coming from.

If you are using your own savings

Lenders require 90 days of bank statements. The statements must:

• Show your name
• Show the account number
• Have nothing blacked out

If part of the down payment is a gift

This requires:

• A signed gift letter
• Proof the funds were deposited

If funds come from selling a property

• Sale agreement
• Mortgage payout statement

Documents Needed If You Already Own Property

If you own another property, lenders must account for those housing costs.

• Current mortgage statement
• Property tax statement showing the annual levy
• Lease agreement if the property is rented

Case Study: A Typical Calgary Purchase

A couple purchasing a $550,000 home with a $55,000 down payment required a $495,000 mortgage.

During the approval process the lender requested:

• Employment letter
• Pay stub
• 90-day bank statements
• Notices of Assessment
• Property tax statement for their rental condo

The approval was briefly delayed because the property tax document did not show the annual levy. Once the correct statement showing a $3,600 annual tax amount was provided, the lender calculated the monthly obligation and approved the mortgage.
