Commission Guide — 2026

What Does BAC Stand For in Real Estate?

BAC stands for Buyer Agent Commission — the compensation paid to the real estate agent who represents the buyer in a property transaction. It is sometimes also referred to as Buyer Agent Compensation or the co-operating commission.

Understanding how BAC works is important for both buyers and sellers. This guide explains the concept, how commission structures work in Canada, recent industry changes, and what it all means for your next real estate transaction.

How BAC Works in a Real Estate Transaction

In a typical Canadian real estate transaction, the commission structure works as follows:

1

Listing Agreement

The seller and their listing agent agree on a total commission rate (e.g., 5%) as part of the listing agreement. This agreement specifies how much of the total commission will be offered as BAC to a buyer's agent.

2

BAC Offered Through MLS

The BAC amount is communicated to other agents through the MLS system, letting buyer agents know what compensation is available if they bring a successful buyer. This encourages broad market exposure for the property.

3

Sale Closes

When the property sells, the total commission is deducted from the seller's proceeds at closing. The listing brokerage retains its share and pays the BAC to the buyer's brokerage. Each brokerage then pays their respective agent according to their individual agreements.

BAC Example: How the Numbers Work

Here is a simplified example of how BAC fits into a real estate commission on a $900,000 home sale with a 5% total commission:

Sale Price$900,000
Total Commission (5%)$45,000
Listing Agent Share (2.5%)$22,500
BAC — Buyer Agent Share (2.5%)$22,500
HST on Total Commission (13%)$5,850
Total Commission + HST$50,850

The split between listing agent and buyer agent is not always 50/50. It depends on what the seller and listing agent negotiated in the listing agreement. HST is charged on top of the commission and is the agent's responsibility to remit.

Recent Changes to BAC in Canada

The real estate industry in Canada has been undergoing significant changes in how commissions — including BAC — are structured and disclosed. Here is what you need to know:

MLS Rules Updated

CREA has removed the blanket requirement for sellers to offer a specific co-operating commission (BAC) through the MLS system. Sellers can still choose to offer BAC, but it is no longer mandatory.

Buyer Representation Agreements

Buyer representation agreements are becoming standard practice. These agreements spell out the services the buyer's agent will provide and the compensation they will receive — whether paid by the seller, the buyer, or a combination of both.

Greater Transparency

There is an industry-wide push for greater transparency in commission structures. Agents are expected to clearly explain how they are compensated, and buyers and sellers should understand the full picture before signing any agreements.

Commissions Remain Negotiable

The fundamental principle has not changed: commissions are not set by law, regulation, or any real estate board. They are always negotiable between the client and their agent. Never hesitate to discuss fees openly with your agent.

What BAC Means for Buyers and Sellers

For Buyers

  • Ask your agent to explain how they are compensated before you start working together
  • Understand your buyer representation agreement — what services are included and what the fee covers
  • In most transactions, the seller still offers BAC, meaning you typically do not pay your agent directly
  • A good buyer's agent adds value through negotiation, market knowledge, and protecting your interests
  • Going without an agent to "save" the commission rarely saves money — sellers do not automatically reduce their price

For Sellers

  • Discuss the total commission and BAC split with your listing agent before signing
  • Offering a competitive BAC encourages buyer agents to show your property, which can lead to more offers and a higher sale price
  • Understand that reducing BAC may limit interest from buyer agents, potentially leaving your property on the market longer
  • All commission terms should be clearly documented in your listing agreement
  • Low BAC does not necessarily save money — properties with low BAC may sell for less or take longer to sell

The portion of the total commission retained by the listing brokerage and their agent.

Buyer Representation Agreement (BRA)

A contract between a buyer and their agent outlining the services provided and compensation terms.

Frequently Asked Questions

What does BAC stand for in real estate?

BAC stands for Buyer Agent Commission (also called Buyer Agent Compensation or Buyer Agent Co-operating Commission). It is the portion of the real estate commission paid to the agent who represents the buyer in a transaction. Historically in Canada, the seller's listing agreement included a total commission that was split between the listing agent and the buyer's agent. The BAC was offered through the MLS system as an incentive for buyer agents to show the property to their clients.

Who pays the buyer agent commission in Canada?

Traditionally, the seller paid both the listing agent commission and the buyer agent commission (BAC) as part of the total commission agreed upon in the listing agreement. The BAC was built into the sale price and paid from the seller's proceeds at closing. However, following regulatory changes and industry shifts, the structure is evolving. Buyers may now negotiate and pay their agent directly in some cases, or the commission arrangement may be structured differently depending on the agreement between the parties. The key point is that commissions are always negotiable — they are not set by law or regulation.

How much is the typical buyer agent commission?

In Ontario and most of Canada, the total real estate commission has traditionally ranged from 3.5% to 5% of the sale price, with the BAC typically being 2% to 2.5%. For example, on a $900,000 home with a 5% total commission, the BAC might be 2.5% ($22,500). However, commission rates are not fixed — they are fully negotiable between the client and their agent. Some agents charge flat fees, tiered rates, or different percentages depending on the price range and services provided. HST (13% in Ontario) applies on top of the commission.

What is the difference between BAC and total commission?

The total commission is the full amount paid for real estate services in a transaction, typically split between two agents. The BAC is specifically the portion allocated to the buyer's agent. For example, if a seller agrees to a 5% total commission, the listing brokerage might retain 2.5% and offer 2.5% as BAC to the buyer's agent. The split is not always equal — it depends on what was negotiated in the listing agreement. In some cases, the listing agent may offer a higher or lower BAC depending on market conditions and the seller's instructions.

Has the BAC system changed in Canada?

Yes. The real estate industry in Canada has been evolving. Key changes include: CREA (Canadian Real Estate Association) removed the requirement for sellers to offer a specific BAC through the MLS system. Buyer representation agreements are becoming more common, where buyers agree to pay their agent directly if the seller does not offer sufficient BAC. Greater transparency in commission disclosure is now expected. These changes aim to increase transparency and give both buyers and sellers more control over how commissions are structured. The fundamental principle remains that commissions are negotiable and should be discussed openly with your agent before entering into any agreement.

Should I use a buyer's agent if I have to pay the commission?

Absolutely. A skilled buyer's agent provides significant value that typically far exceeds their commission: access to MLS listings and off-market opportunities, expert negotiation (often saving you more than their fee), guidance through inspections, financing, and legal requirements, protection of your interests throughout the transaction, and knowledge of fair market values to prevent overpaying. In most transactions, the seller still covers the BAC as part of the sale. Even in cases where buyers pay their agent directly, the agent's expertise in negotiation alone can save you thousands. Going without representation to save a commission often costs buyers more in the long run.
