Key takeaways
- TD’s 2026 agentic AI mortgage tool aims to reduce pre-adjudication work from hours to minutes while keeping a human underwriter responsible for the final decision.
- Nesto’s Maestro AI is being positioned around deterministic, auditable underwriting decisions with clear narratives for governance and compliance.
- Consumers are open to AI convenience, but 68% of surveyed homebuyers say transparent disclosure of AI involvement is important or essential.
- Borrowers should expect more automation, but should still ask how AI is used, who reviews the file, and how decisions can be explained or challenged.
What changed in 2026
AI in mortgages is moving beyond basic chat tools and research assistants. The important 2026 development is the arrival of more advanced underwriting systems that can review documents, calculate income, validate policy and consent, search for discrepancies, and prepare underwriting notes — while promising a clear audit trail and human oversight.
TD publicly detailed its first agentic AI mortgage application on May 21, 2026, positioning it as a way to reduce pre-adjudication time “from hours to minutes.” The key accountability point is that TD says the system operates under a Trustworthy AI governance framework with mandatory human-in-the-loop oversight, meaning the human underwriter remains responsible for the final decision.
Fintech lenders are moving in a similar direction. Nesto’s Maestro AI platform, highlighted around August 25, 2026, is being marketed as an underwriting engine that produces deterministic, auditable decisions with clear narratives. Earlier 2026 coverage of Nesto’s funding also emphasized decision nodes that are fully explainable, auditable and compliant with regulatory requirements, again with human oversight. Together, these developments point to a shift away from opaque “black box” mortgage AI and toward traceable decision logic.
Why mortgage shoppers are still cautious
Canadian borrowers are not rejecting AI outright. The tension is that people like the speed and convenience, but they do not want an unexplained machine deciding whether they qualify for a home. A May 9, 2026 survey of homebuyers found that 68% consider transparent disclosure of AI involvement important or essential, while 37% — rising to 61% among baby boomers — say disclosure should be mandatory.
The same survey shows concern around automated valuations and verification. Nearly half of respondents believe lenders or insurers should not conduct AI valuations without prior approval, and 44% would pay a professional to verify AI-generated decisions. That is a clear message for the mortgage industry: speed is welcome, but trust still depends on transparency, consent and human accountability.
What this means for your mortgage application
For buyers, refinancers and renewing homeowners, the practical impact may be faster file review, especially where the work involves document collection, income calculation and policy checks. But faster does not mean every file becomes simple. If your income is variable, self-employed, commission-based, newly changed, or supported by multiple documents, you may still need a human advisor and underwriter to understand the full picture.
- Ask whether AI is being used to review documents, income, valuations or recommendations.
- Ask who has final responsibility for the decision and whether a human underwriter reviews the file.
- Ask for a clear explanation if your approval includes unexpected conditions or if your application is declined.
- Keep your documents consistent and up to date, because newer tools are specifically designed to identify discrepancies.
Accountability is becoming a regulatory priority
Regulators are also paying closer attention. OSFI’s 2025-2026 Annual Risk Outlook identifies AI as a source of integrity, security and fraud risk and notes supervisory work to assess institutions’ AI risk management and preparedness. The Mortgage Broker Regulators’ Council of Canada’s 2026-2029 Strategic Plan also lists artificial intelligence and private lending risks as key priorities. Industry coverage further reports OSFI engaging banks on AI underwriting default rates and how credit risk is evaluated and monitored.
For consumers, this is encouraging, but it does not remove the need to ask questions. The best use of AI in mortgages should make the process faster and clearer — not harder to understand. If an automated system helps review your file, you should still be able to understand what information mattered, what conditions apply, and what options may still be available through other lenders.
The bottom line
Mortgage AI is becoming more capable, but the most important 2026 shift is not just speed — it is accountability. The direction of travel is toward tools that are explainable, auditable and supervised by people, which should help borrowers better understand decisions and reduce the risk of unexplained outcomes over time.
