Short answer first. On a standard residential mortgage in BC, working with a broker costs you nothing: the lender that funds your mortgage pays the broker a finder's fee. Fees only enter the picture in specific situations, mainly private lending and some hard-to-place files, and BCFSA rules require they be disclosed to you in writing before you're committed. That's the whole answer; the rest of this post is the how and the edge cases.
How brokers get paid
When a mortgage funds, the lender pays the broker a finder's fee, a fraction of the mortgage amount. It's how lenders without branch networks acquire customers: instead of paying for buildings and tellers, they pay brokers for completed files. That fee doesn't come out of your rate. Broker-channel lenders price competitively precisely because brokers put their rates next to everyone else's all day long.
“So you're biased toward whoever pays most?”
Fair question. Finder's fees are similar across mainstream lenders, so steering a file for an extra sliver of fee makes no sense, and it would be a short career move anyway: this business runs on referrals, and referrals come from mortgages that fit. There's also a legal layer: brokers in BC are licensed by the BC Financial Services Authority and required to disclose to you how they're paid on your file. You never have to wonder.
You pay nothing, the lender pays the broker, and the disclosure paperwork shows you exactly what was paid. It's one of the more transparent corners of the industry.
Where fees legitimately exist
Private lending. Private lenders don't pay finder's fees, so a broker fee applies, disclosed and agreed in writing before anything proceeds.
Very complex or small files. Occasionally a hard-to-place file involves a fee where the lender compensation doesn't cover the work. Same rule: in writing, up front, or it shouldn't happen.
Commercial mortgages. Different world, typically fee-based by design.
The red flag version
A fee that appears late in the process, or that nobody will put in writing, is not how this is supposed to work. If you meet one, walk.

Frequently asked questions
Do I pay more interest to cover the broker's fee?
No. The finder's fee is the lender's customer-acquisition cost, not a markup on your rate. Broker-channel lenders compete directly on rate against banks, which keeps their pricing sharp.
How do I know what my broker was paid?
BC brokers must disclose their compensation on your file in the regulatory paperwork you sign. If you want the number explained, ask; a good broker will walk you through it happily.
Is a broker free for refinances and renewals too?
Yes, the same lender-paid model applies to standard refinances and renewal switches, not just purchases.
