What Is a Mortgage Commitment and Why It Matters in Ontario

By: Amanda Willing

Summary:

A mortgage commitment is one of the most important—but often misunderstood—steps in the home buying process in Ontario. It is the lender’s formal confirmation that they are willing to provide financing, but it usually comes with specific conditions that must still be satisfied before closing. Many buyers mistakenly treat it as “final approval,” when in reality, it is still conditional. Understanding this distinction can prevent last-minute financing issues and closing stress.

What a Mortgage Commitment Actually Means

A mortgage commitment is a written document from your lender confirming that:

• Your mortgage application has been approved in principle

• The lender is willing to provide financing

• The approval is subject to certain conditions

In simple terms, it means: “We are prepared to lend you the money—if everything checks out.”

It is not the final release of funds.

Mortgage Commitment vs. Final Approval

This is where many first-time buyers get confused.

Mortgage Commitment

• Conditional approval

• Issued after reviewing your application and documents

• Still subject to requirements being met

Final Funding (Closing Approval)

• Occurs right before or on closing day

• All conditions have been satisfied

• Funds are actually released to complete the purchase

The gap between these two stages is where most financing risks arise.

Common Conditions in a Mortgage Commitment

A mortgage commitment usually includes conditions such as:

Property Appraisal

The lender confirms the home is worth the purchase price.

Income Verification

Updated proof of employment or income stability may be required.

Credit Confirmation

Lenders may re-check credit before closing.

Down Payment Verification

Proof that funds are available and properly sourced.

Insurance Requirements

Home insurance must often be arranged before closing.

No Material Changes

Your financial situation must remain stable until closing.

Why This Stage Matters So Much

The mortgage commitment is a critical checkpoint because it connects:

• Your financing

• Your purchase agreement

• Your closing date

If conditions are not met, the lender can:

• Delay funding

• Change approval terms

• Or, in serious cases, withdraw financing

This can put the entire purchase at risk.

What Can Go Wrong After a Mortgage Commitment?

Even after receiving a commitment, issues can still arise.

Job Changes

Losing or changing employment before closing can affect approval.

New Debt

Taking on new loans or credit obligations may impact affordability.

Property Issues

Appraisal problems can reduce the lender’s willingness to fund.

Missing Documents

Incomplete paperwork can delay or block final approval.

Credit Changes

Late payments or new credit inquiries can raise concerns.

Why First-Time Buyers Should Pay Extra Attention

First-time buyers often assume:

“I got approved, so everything is guaranteed.”

But lenders still reassess risk right up until closing.

This is why the period between mortgage commitment and closing is critical. Financial discipline during this time is essential.

How Lawyers and Lenders Work Together

Once a mortgage commitment is issued:

• The lender sends instructions to your lawyer

• Your lawyer prepares closing documents

• Final conditions are reviewed before funds are released

• Any issues are addressed before closing day

This coordination ensures the property can be legally transferred once financing is confirmed.

Can a Mortgage Commitment Be Withdrawn?

Yes, in some cases.

A lender may withdraw or change a commitment if:

• Key conditions are not satisfied

• Financial circumstances change

• The property no longer meets lending criteria

• Fraud or misrepresentation is discovered

This is why maintaining financial stability before closing is so important.

Common Misunderstandings

“Mortgage commitment means I’m fully approved.” 

Not necessarily—it is still conditional approval.

“Once I get it, I can relax financially.” 

You still need to avoid major financial changes before closing.

“The lender cannot change their mind.” 

They can, if conditions are not met.

“It guarantees closing will happen.” 

It significantly improves the likelihood, but does not guarantee it.

Key Takeaways

• A mortgage commitment is conditional approval, not final funding

• It includes requirements that must be met before closing

• Financial changes after approval can still affect your mortgage

• The period between commitment and closing is critical

• Understanding conditions helps avoid last-minute surprises

Final Thoughts

A mortgage commitment is an important milestone in the home buying process, but it is not the finish line. It represents a lender’s willingness to fund—provided all conditions remain satisfied up to closing.

For many buyers, especially first-time purchasers, understanding this stage helps prevent unnecessary stress and financial risk.
