TRESA Explained: What Ontario's New Real Estate Act Means for You

The Trust in Real Estate Services Act, 2002 (TRESA) is the legislation that governs real estate trading in Ontario. It came fully into force on December 1, 2023, replacing the Real Estate and Business Brokers Act, 2002 (REBBA 2002) as the active regulatory framework.

If you are studying for your real estate licence, already practising, or a consumer buying or selling property in Ontario, TRESA directly affects you. TRESA is the legal backbone of the Ontario real estate licensing pathway. This guide explains what TRESA is, what changed from REBBA, and what every student and registrant needs to know in 2026.

Key Takeaways

• TRESA replaced REBBA 2002 as the governing legislation for real estate in Ontario, effective December 1, 2023.
• Key changes include the legalization of Personal Real Estate Corporations (PRECs), strengthened consumer protection, enhanced RECO discipline powers, and updated rules around multiple representation.
• Designated representation provisions are included in TRESA but have not yet been proclaimed into force as of 2026.
• All pre-registration education and exams now test TRESA content exclusively — study materials referencing REBBA are outdated.
• TRESA introduced the concept of "self-represented parties" to replace the old "customer" designation.

What Is TRESA?

TRESA stands for the Trust in Real Estate Services Act, 2002. Despite the 2002 date in its name, the Act underwent major amendments through the Trust in Real Estate Services Act, 2020 (Bill 145), and these amendments came fully into force on December 1, 2023.

TRESA serves as the legal foundation for:

• How real estate professionals are registered and regulated in Ontario
• The rules that govern the relationship between agents, their clients, and the public
• RECO's mandate, powers, and enforcement tools
• Consumer protection mechanisms, including the Consumer Protection Fund
• Ethical standards and the Code of Ethics for registrants

Think of TRESA as the rulebook. RECO is the referee that enforces it.

Why Did TRESA Replace REBBA?

REBBA 2002 served Ontario for over two decades, but the real estate landscape changed dramatically during that period. Several gaps became apparent:

• Consumer expectations evolved. Buyers and sellers wanted more transparency about who was working for whom in a transaction, especially in multiple-offer situations.
• The industry needed corporate structures. Under REBBA, salespersons and brokers could not incorporate their practices. This put them at a tax disadvantage compared to other professionals like lawyers and accountants.
• Discipline processes were slow. REBBA's enforcement mechanisms were cumbersome, making it difficult for RECO to address minor violations quickly.
• Representation rules were outdated. The old "customer vs. client" framework did not adequately address the complexity of modern real estate relationships.

TRESA was designed to address all of these issues while modernizing the regulatory framework for the current market.

Key Changes from REBBA to TRESA

1. Personal Real Estate Corporations (PRECs)

One of the most anticipated changes: TRESA allows salespersons and brokers to incorporate as Personal Real Estate Corporations.

What this means in practice:

• You can now form a corporation to receive your real estate commissions, rather than receiving all income personally.
• PRECs can provide tax planning advantages, including income splitting, dividend distribution, and access to the small business tax rate on the first $500,000 of active business income.
• The individual salesperson or broker must still be personally registered with RECO — the PREC does not replace personal registration.
• The PREC must be registered with RECO as well, and there are specific rules about what activities the PREC can and cannot conduct.

Important limitations:

• A PREC can only have one registrant as a director and shareholder. You cannot form a PREC with another agent.
• The PREC cannot directly employ other salespersons.
• The registrant remains personally liable for their professional conduct — incorporating does not shield you from RECO discipline.

2. Self-Represented Parties (Replacing "Customers")

Under REBBA, people who chose not to be represented by an agent were called "customers" and received a minimal level of service. TRESA replaces this with the concept of self-represented parties.

What changed:

• Under TRESA, a person who is not represented by a registrant is a "self-represented party," and registrants have specific obligations when dealing with them.
• The old "customer service agreement" is gone. Instead, there are clearer rules about what information you must provide to self-represented parties and what duties you owe them.
• Registrants must ensure that self-represented parties understand they are not being represented and that the registrant is acting for the other party in the transaction.

3. Multiple Representation (Updated Rules)

Multiple representation occurs when one registrant (or brokerage) represents both the buyer and the seller in the same transaction. TRESA strengthens the rules around this:

• Informed written consent is mandatory. Both parties must consent in writing to multiple representation before the registrant can act for both sides.
• Disclosure requirements are enhanced. The registrant must clearly explain the limitations of multiple representation — that they cannot advocate for either party's position and must treat both parties fairly.
• The brokerage is the entity that is in multiple representation, not just the individual salesperson. Even if two different salespersons within the same brokerage represent the buyer and seller respectively, the brokerage is in a position of multiple representation.

4. Designated Representation (Not Yet in Force)

TRESA includes provisions for designated representation, which would allow a brokerage to designate individual salespersons to represent different parties in the same transaction, avoiding the limitations of multiple representation.

Critical note for students: These designated representation provisions are included in TRESA's text but have not yet been proclaimed into force as of 2026. This means they are not operative law yet. Your exam may test your knowledge of what designated representation is and that it exists in TRESA, but it is not currently a practice option.

When (and if) designated representation is proclaimed, it would work like this:

• A brokerage designates Salesperson A to represent the buyer and Salesperson B to represent the seller.
• Each designated salesperson owes full fiduciary duties to their respective client.
• The brokerage itself is not in a position of multiple representation.
• Information barriers (sometimes called "Chinese walls") would be required between the designated agents.

5. Enhanced RECO Discipline Framework

TRESA significantly strengthened RECO's ability to enforce the rules:

• Administrative penalties (fines) — RECO can now impose monetary penalties directly for less serious violations without going through a full tribunal process. You can view past discipline decisions on RECO's website. Under REBBA, even minor infractions could require lengthy formal proceedings.
• Increased maximum penalties — TRESA raised the maximum fines and expanded the range of sanctions available to RECO.
• Compliance orders — RECO can issue orders requiring registrants to take specific actions to come into compliance.
• Faster process — The streamlined discipline framework means that violations are addressed more quickly, protecting consumers and maintaining public trust.

6. Enhanced Consumer Protection

• Strengthened Consumer Protection Fund — The fund that compensates consumers for financial losses caused by registrant misconduct was updated under TRESA.
• Improved disclosure requirements — Registrants must provide more detailed information to consumers about their services, fees, and the nature of the agency relationship.
• Open offers concept — TRESA includes provisions for an open offers process (allowing sellers to see competing offers), though the specific regulations for implementation have not yet been finalized.

7. Updated Code of Ethics and Standards

While the Code of Ethics existed under REBBA, TRESA updated the regulatory framework to strengthen ethical obligations:

• Clearer duties regarding honesty and accuracy in advertising
• Updated rules on handling confidential information
• Strengthened obligations around material facts and disclosure
• Modern provisions addressing digital marketing and online conduct

What TRESA Means for Students

If you are currently enrolled in the pre-registration program through Humber, Algonquin, Fleming, or Career College Group, here is what you need to know:

All Exams Test TRESA

Every exam in the salesperson program — from Course 1 through the Simulations — tests the TRESA framework. There are no REBBA questions on current exams. If you are using study materials published before 2024, they may reference REBBA terminology, forms, or processes that no longer apply.

Key TRESA Concepts Tested on Exams

Based on the current competency profile, students should have a strong grasp of:

• The purpose and structure of TRESA — Why it exists, what it replaced, and its core objectives
• RECO's mandate under TRESA — Registration, discipline, consumer protection
• Representation concepts — Client vs. self-represented party, multiple representation rules, the unproclaimed designated representation provisions
• PRECs — What they are, requirements, limitations, and tax implications at a high level
• The Code of Ethics — Specific obligations including duty of care, confidentiality, avoiding conflicts of interest, and disclosure of material facts
• Consumer Protection Fund — Purpose, when it applies, and how consumers access it

TRESA Sections Every Student Should Know

While you do not need to memorize section numbers, being familiar with the structure helps:

• Part I — Definitions and interpretation (know the key definitions: "registrant," "brokerage," "trade," "self-represented party")
• Part II — Registration (requirements, classes of registration, conditions)
• Part III — Duties of registrants (the Code of Ethics, disclosure, trust funds)
• Part IV — Complaints, inspection, and discipline (RECO's enforcement powers)
• Part V — Consumer Protection Fund
• Part VI — General provisions (PRECs, administrative penalties, regulations)

ExamAce Course 1 practice questions cover TRESA extensively, with scenario-based questions that test your ability to apply the legislation — not just recall it.

What TRESA Means for Licensed Agents

If you are already registered and practising, TRESA brought several changes to your daily practice:

PRECs Are Available

If you have been waiting to incorporate, PRECs are now fully operational. Consult an accountant to determine if a PREC makes financial sense for your situation — the tax benefits depend on your income level, expenses, and personal tax situation. You must register your PREC with RECO and comply with the specific PREC regulations.

Review Your Representation Agreements

TRESA's updated representation rules mean your buyer and seller representation agreements should reflect the current legislation. If your brokerage is still using REBBA-era forms, raise this with your broker of record. OREA has updated its standard forms to align with TRESA.

Multiple Representation Requires Extra Care

The enhanced disclosure and consent requirements for multiple representation mean you need to be even more diligent about obtaining informed written consent before entering a multiple representation situation. Failure to do so is a serious regulatory violation under TRESA with potentially stiffer penalties than under REBBA.

Stay Current on Compliance

RECO's expanded discipline powers mean that compliance matters more than ever. Minor violations that might have been overlooked under REBBA can now result in administrative penalties. Invest in continuing education to stay current with your obligations.

RECO mandates annual continuing education, and the CE annual update course covers TRESA amendments and enforcement trends. ExamAce CE prep helps you prepare for the CE assessment efficiently.

TRESA vs REBBA: Quick Comparison

Frequently Asked Questions

Is TRESA the same as REBBA with a new name?

No. TRESA is substantially different from REBBA. While some foundational concepts carry over (registration requirements, the Code of Ethics), TRESA introduces entirely new provisions (PRECs, designated representation, administrative penalties) and significantly reworks others (consumer protection, self-represented parties, multiple representation). Treating TRESA as "just REBBA renamed" will lead to wrong answers on your exams.

When did TRESA come into effect?

TRESA received Royal Assent in 2002, but the major amendments (through the Trust in Real Estate Services Act, 2020 / Bill 145) came fully into force on December 1, 2023. Some provisions, like designated representation, are in the legislation but have not yet been proclaimed into force.

Will designated representation be proclaimed soon?

There is no confirmed date. RECO and the Ontario government have indicated that further consultation and regulation-making are needed before designated representation can be proclaimed. Students should know what it is and that it exists in TRESA, but should understand it is not currently operative.

Do I need to know REBBA for my exams?

No. Current exams test TRESA exclusively. However, understanding the historical context (why TRESA replaced REBBA and what problems it addressed) can help you understand the rationale behind current regulations. You should not study REBBA content or use REBBA-based practice questions to prepare for current exams.

TRESA is not just a regulatory footnote — it is the foundation of everything you will do as an Ontario real estate professional. Understanding it deeply, rather than memorizing surface-level facts, is what separates students who pass comfortably from those who struggle. ExamAce practice questions are built on the 2026 TRESA curriculum, with scenario-based questions that test real understanding.
