Personal guarantee
Also called: personal guarantor
A promise you make, as a person, to pay back a loan to your company if the company does not pay.
Lenders can ask business owners to personally guarantee a loan made to their company. If the company does not pay, the lender can take legal action against the guarantor personally. A guarantee can be for a set dollar amount or for the whole loan, so check the limit before you sign. For example, as of November 13, 2026, under CMHC's MLI Select, the borrower and guarantor must guarantee 100% of a construction loan until the planned rents are reached and stay steady for 12 months in a row. After that, it can drop to 40%. On an existing building it is 40% (CMHC MLI Select product sheet, 2025).

Policy rate (Bank of Canada)
Also called: policy interest rate, overnight rate, target for the overnight rate, key interest rate
The Bank of Canada's main interest rate: its target for the rate banks and other financial institutions charge each other on one-day loans. It is the Bank's main tool to control inflation.
You cannot borrow at the policy rate, but changes to it lead to similar changes in short-term rates. These include lenders' prime rates, which lenders use as the base for variable-rate mortgages and lines of credit. The Bank of Canada does not set mortgage rates. A change can also affect longer-term rates, especially if people expect it to last. The Bank announces the rate on eight fixed dates each year, and in special cases at other times.

Portability (porting)
Also called: porting, port a mortgage, portable mortgage
Taking your current mortgage, with its balance, rate and terms, to a new home when you sell and buy, so you do not break it.
Porting can save you a prepayment penalty when you move during your term. Not every mortgage can be ported, so ask your lender whether yours is eligible and what restrictions apply. If the new home costs less than what you still owe, you may still have to pay a prepayment penalty. If you need to borrow more for the new home, ask your lender how that works.

Posted rate
Also called: posted interest rate, discounted rate, advertised rate
The rate a lender advertises for each mortgage term. If you are given a lower rate, that lower rate is called a discounted rate.
Posted rates matter even after you sign, because many lenders use them to work out an IRD prepayment penalty. To do that, the lender usually compares a rate from your contract, such as your own rate or the posted rate when you signed, with today's posted rate for a similar term. Sometimes the discount you were first given is taken off today's rate. A variable rate is often set as the lender's prime rate plus a percentage.

Pre-approval (rate hold)
Also called: pre-approval, preapproval, pre-approved, rate hold, rate guarantee, pre-qualification
A lender's early look at your finances that shows how much it may lend and at what rate. It can hold a rate for a while, but it is not a final approval.
As of November 13, 2026, depending on the lender, a pre-approval can lock in a rate for 60 to 130 days. It does not guarantee you a mortgage: the lender still has to give its final approval (FCAC).

Prepayment penalty
Also called: penalty, mortgage penalty, prepayment charge, break fee, cost to break, breaking your mortgage
A fee your lender may charge if you pay off, move or break your mortgage before the term ends, or if you pay more than your contract allows. It is most often three months' interest or the IRD, whichever is more.
You can be charged a penalty if you break your mortgage contract, move it to another lender before the term ends, pay it off early (including when you sell), or pay more than your prepayment privileges allow. The amount is usually the higher of two numbers: three months' interest on what you still owe, or the interest rate differential (IRD). Each lender works it out in its own way, so check your mortgage contract. You may also have to pay an administration fee. Example from the Financial Consumer Agency of Canada: a $200,000 balance at 6% has 36 months left, and the lender's posted rate for a 36-month term is 4%. Three months' interest is $3,000 and the IRD is $12,000, so the penalty is $12,000. The penalty is for paying before the term ends, so waiting until the end of your term (the maturity date) avoids it. An open mortgage can be paid down at any time without one.

Prepayment privileges
Also called: prepayment privilege, prepayment option, double-up payment
The extra you can pay on your mortgage each year with no penalty. It is on top of your usual payments, and your contract sets how much.
Many closed mortgages let you pay extra: a lump sum on dates set in your contract, a higher regular payment, or both, up to a limit in your contract. These privileges vary from lender to lender, and not every lender allows them on closed mortgages, so read your contract. Paying more than the privilege allows can bring a prepayment penalty, and once you raise your payment you normally cannot lower it again until the term ends. With an open mortgage you can pay extra without a penalty.

Presale and assignment
Also called: presale, pre-sale, assignment sale, presale condo
A presale is buying a condo or other strata home from a developer before it is built. An assignment is selling your right to buy it to someone else before it is done.
With a presale, you sign a purchase agreement before the building is finished and registered. If you pass that right to buy to someone else before completion, that is an assignment. In B.C., the developer must report it to the province's Condo and Strata Assignment Integrity Register. As of November 13, 2026, a presale contract held less than 730 days may be caught by the B.C. home flipping tax (Province of B.C.). The federal flipping rule can also treat a right to buy a home in Canada that was held less than 365 days as business income, with some exceptions (Income Tax Act, s. 12).

Prime lender (A lender)
Also called: prime lender, A lender, A-lender, A-side, A side, prime (A) lender, traditional lender, institutional lender
A bank, a credit union or one of many monoline lenders: the regular kind of lender. Its rates are usually lower than a B or private lender's, but you need proof of income, good credit and debts within its limits.
Mortgage lenders are often grouped into three kinds: prime (A), alternative (B) and private. Government reports call prime lenders conventional lenders, a group CMHC lists as including chartered banks, credit unions and monoline lenders. They approve a file mainly on whether you can make your regular payments until the loan is paid off, and their rates are usually lower than an alternative or private lender's (CMHC). A prime residential mortgage usually has no lender fee (Ramin, October 21, 2026). Banks and other federally regulated lenders must follow the mortgage underwriting rules of OSFI, the federal regulator (Guideline B-20). Credit unions are mostly regulated by their province and often use their own stress test (Bank of Canada). For an insured mortgage, as of November 13, 2026, housing costs can be up to 39% of gross income (GDS) and all debts up to 44% (TDS) (CMHC). When a file does not fit a prime lender's rules, an alternative (B) lender may be the next step. The word prime in prime lender names this kind of lender. It is not the same thing as the prime rate.
In Ramin's words (October 21, 2026): “prime: no lender fee, broker fee rare”

Prime rate
Also called: prime lending rate, prime interest rate, bank prime, prime plus, prime minus, lender's prime
The base rate a lender uses to set rates on loans such as variable-rate mortgages and lines of credit. Each lender sets its own, and it is shaped by the Bank of Canada's key interest rate.
Variable rates are often quoted as prime plus or minus a set amount. For example, at prime plus 1%, if prime is 3.5% your rate is 4.5%, and if prime rises to 3.7% your rate becomes 4.7%. Each lender sets its own prime rate based on what it costs the lender to get money. That cost is influenced by the Bank of Canada's target for the overnight rate, often called its policy rate, so a lender's prime rate may change when the Bank of Canada changes its policy rate. Every week, the Bank of Canada publishes the most common prime rate at Canada's six biggest banks. Today's figure is on our prime rate page. The prime rate is not the same thing as a prime lender: one is a rate, the other is a kind of lender.

Principal and interest
Also called: P&I, interest portion
The two parts of a mortgage payment: principal pays down what you borrowed, and interest is what the lender charges for the loan.
On a regular blended payment, each payment goes first to the interest owing and then to the principal, so early on a bigger share goes to interest and later more of it pays down the principal. Taxes or insurance collected with your payment are not part of principal and interest. Calculators often show the two together as "P&I". On commercial loans, Ramin describes the variable payment in his own words, quoted below.
In Ramin's words (October 16, 2026): “the variable is not blended, it's just principal and interest”

Private lender
Also called: private mortgage, private lending, private money, private first mortgage, private second mortgage, private side
A lender that is not a bank, a credit union or a B lender, such as a mortgage investment corporation or a private investor. It makes short loans at higher rates to people who banks and other usual lenders turn down.
Private lenders are not regulated the way banks are and do not have to follow federal mortgage standards such as the stress test (Bank of Canada). They usually lend for short terms at higher rates and often offer interest-only payments (CMHC). On a residential private mortgage, the lender fee is usually 1% to 3% and the brokerage fee 1% to 2%; brokerage starts at $2,500 and the lender fee at about $2,500 (our financing fees calculator). Because the term is short, a private mortgage needs a plan to pay it out, such as a sale or a move to a B lender or a prime lender. A B lender is not the same as a private lender.
In Ramin's words (November 4, 2026): “Is a B lender the same as a private lender? Right? No.”

Professional mortgage program
Also called: physician mortgage program, medical professional program, professional program, doctor mortgage, dentist mortgage
A home mortgage program for doctors, dentists and some other licensed professionals. It can count the income you expect to earn and allow a small down payment.
Each lender publishes its own program and income table, and the professions it covers vary; some lenders do not write every profession. Some lenders count projected (expected) income from their own published tables. A physician can need as little as 5% of their own money: some lenders go to 95% of the value, and others at 90% let the last 5% be borrowed, for example from a physician's line of credit, at a higher insurance premium (lender factsheets dated June to July 2026, supplied by Ramin on August 3, 2026; Ramin's decision, recorded in our rules on August 3, 2026). Insurers charge more for a borrowed down payment: CMHC's premium at 90.01% to 95% is 4.50% with a non-traditional down payment against 4.00% with your own money.

Purchase plus improvements
Also called: purchase plus improvement, PPI, purchase plus renovations
A purchase mortgage that also covers planned renovations, so the work is paid for in the same mortgage. Insured programs allow a small down payment.
The lender bases the loan on the lower of two amounts: the home's value after the work, or the price plus the direct cost of the work. You give quotes up front. The renovation money is paid out as the work is done and confirmed with proof, such as paid invoices, before and after photos or an inspector's report. As of November 13, 2026, Sagen's program allows up to 95% loan to value on 1 and 2 unit homes, including the cost of the work. You need 5% down on the first $500,000 and 10% on the part above, for homes under $1,500,000 (Sagen, Purchase Plus Improvements Program). Furniture and appliances do not count.
