Loanmoose.ca is a loan matching and comparison service. It is not a lender, it does not make credit decisions, and it cannot approve anyone. The sections below explain how the two roles work, so you can decide whether to sign at all.
The two roles in plain terms
A co-signer signs the loan agreement itself and becomes a borrower. The lender treats that debt as belonging to both people on the contract. Payments, missed payments and defaults are recorded against both names, and if the loan stops performing, the lender can generally pursue either borrower for the full outstanding balance without having to exhaust the other one first.
A guarantor does not sign the loan agreement. They sign a separate guarantee contract with the lender, promising to pay if the primary borrower does not. The primary borrower remains the only borrower of record. Because the guarantee is a side agreement rather than the loan itself, many lenders do not report it to the credit bureaus while the account is in good standing. The obligation is still legally enforceable, and it can be called once the borrower misses payments, depending on how the guarantee is written.
Both roles expose you to the entire debt, not a share of it. That is the part people most often misread. Helping out is not a half measure in either case, and the amount can grow over time if the underlying product is a revolving one.
How each role appears on a credit file
Canada has two national credit reporting bureaus: Equifax Canada and TransUnion Canada. Both compile information that lenders send them, and both can hold a file on you at the same time, so the same account may look slightly different depending on which file a lender pulls.
What a lender reports depends on which contract you signed:
- Co-signer: because you are a borrower, the account can be reported on your file alongside the primary borrower's. The balance, the payment history and, for revolving products, the utilization can all show up, and other lenders can consider all of it when they review your file later.
- Guarantor: because you are not a borrower, the guarantee itself is usually not reported while the loan performs. If the borrower defaults and the lender calls on you, collection activity, a judgment or a settlement can land on your file and stay there according to the bureau's own retention rules.
Insolvency has its own timelines, and no co-signing arrangement changes them. A consumer proposal stays on a credit report for 3 years after completion, or 6 years from filing, whichever comes first. A first bankruptcy stays on a credit report for 6 years after discharge. Only a licensed insolvency trustee can administer a consumer proposal or a bankruptcy, and the Office of the Superintendent of Bankruptcy Canada sets out how those proceedings work. If a borrower you guaranteed enters one of those processes, the trustee's role is to deal with that borrower's debts, not to protect you.
What the liability actually means for the person helping
In both roles, the practical exposure is the same: the lender can come after you for what the borrower owes, plus any interest and costs the contract allows.
Co-signing tends to bite sooner. Because the account sits on your credit file from day one, a missed payment by the borrower can affect your credit score before you even know it happened. It also counts against you when you apply for your own credit, since lenders look at your existing obligations.
Guaranteeing tends to bite later but harder. Nothing may appear on your file for years, and then a single default can hand you a debt you never budgeted for, sometimes after the borrower has stopped answering calls.
Lenders do not all treat these obligations identically when they calculate how much you can afford. At federally regulated mortgage lenders, the guideline ceiling for total debt service ratio is about 44%, and uninsured mortgages are qualified at the greater of the contract rate plus 2 percentage points and 5.25%, under OSFI Guideline B-20. A co-signed loan is generally treated as your debt in that math, which can reduce how much you can borrow for a home while the loan is outstanding.
Provincial rules matter here too. Lending in Canada is licensed provincially, so the regulator and the rules differ depending on where you live and who is doing the lending.
Co-signer vs guarantor, side by side
| Point of comparison | Co-signer | Guarantor |
|---|---|---|
| What you sign | The loan agreement, as a borrower | A separate guarantee contract |
| Position on the loan | Borrower of record | Not a borrower; a third-party obligor |
| When liability starts | Immediately, from the first payment due | Contingent, usually only after the borrower defaults, as the guarantee sets out |
| Who the lender can pursue | Either borrower, generally for the full balance | The guarantor, after the borrower fails to pay and any required notice is given |
| Credit file while the account performs | Generally reported on your file, including balance, payment history and, for revolving credit, utilization | Generally not reported |
| Credit file after default | Arrears and collections can appear | Collections, judgments or settlements can appear if the guarantee is called |
| Effect on your own borrowing | The debt is generally counted in your debt service ratios | Usually not counted unless the guarantee is called |
| How you get out | The borrower refinances or pays out, and the lender releases you | The lender releases you, or the guarantee ends under its own terms |
These are general patterns, not universal rules. Terms vary by lender and by province, and the contract you sign is what governs.
How this connects to loans and lines of credit
The loan vs line of credit distinction changes what you are signing up for as much as the role does. A loan is a fixed amount advanced once and repaid on a schedule. A line of credit is a revolving limit you can draw, repay and draw again. The Financial Consumer Agency of Canada explains how personal loans work and what lenders must disclose to you.
If you are asked to co-sign or guarantee a line of credit, remember that the balance can rise over time. You are not only backing today's balance. A co-signer on a revolving line is exposed to whatever the borrower draws later, up to the limit.
An offer that arrives in the mail or in a banking app is not the same thing as an approval. A pre approved line of credit is typically a lender's invitation to apply based on information it already holds; the lender still verifies income, debts and credit when you accept, and it can decline or change the terms. That matters for the person being asked to help, because their file becomes part of what gets checked.
Some products leave less room for a guarantee than people expect. At federally regulated lenders, a home equity line of credit is generally limited to 65% of appraised property value, with total secured lending usually capped at 80%, so the equity available to support the arrangement may be smaller than assumed.
When the borrower cannot qualify alone
People often look for a workaround when a lender says no. You will see the search phrase 'guaranteed line of credit with bad credit canada' used in advertising and in results pages. Treat that wording carefully: no lender is obliged to lend, and no third party can promise you someone else's approval. What actually decides the answer is the lender's own criteria, the province's licensing rules, and the borrower's file.
High-cost short-term credit is a separate market with its own limits. A payday loan is generally up to $1,500 for a term of 62 days or less. Where a province operates a licensed payday lending regime, the federal Payday Lending Regulations cap the cost of borrowing at $14 per $100 advanced, and some provinces set a lower cap that applies instead. Quebec does not license payday lending, which effectively prohibits the model there.
For any credit agreement, the Criminal Code criminal rate of interest is 35% per year under section 347, whether or not a co-signer or guarantor is involved.
If the underlying problem is an unaffordable debt load rather than a thin credit file, adding a co-signer does not fix it. It spreads the risk to someone else. Formal debt relief options are described by the Office of the Superintendent of Bankruptcy Canada, and only a licensed insolvency trustee can administer them.
Rates themselves are set by lenders, not by any public benchmark. The Bank of Canada publishes the policy interest rate, the prime rate, conventional mortgage rates and Government of Canada benchmark bond yields. These are benchmarks, not offers, and no lender is obliged to lend at them. The lowest rates are only available to the most qualified applicants.
Before you sign: questions to ask
- Am I a borrower or a guarantor on this contract, and where exactly does it say so?
- What is the total amount I could be liable for, including interest, fees and any limit increases on a revolving product?
- Will this appear on my credit file, and how will it be reported?
- What has to happen for me to be released, and will the lender confirm that in writing?
- Does the contract limit how long the guarantee lasts or how much it covers?
- What happens if the borrower and I both stop paying?
Get the answers in writing. Verbal assurances from a borrower or a salesperson are not the contract. A lawyer or a licensed credit counsellor can review the agreement for you, and for a commitment of this size that is usually worth the cost. This guide explains how the roles work; it is not financial, legal or tax advice, and the right answer depends on your circumstances.
Where loanmoose.ca fits
Loanmoose.ca matches Canadians with lenders and compares options across the market. It does not lend, does not set rates, does not decide who qualifies, and does not tell you whether to co-sign or guarantee. If you are the person doing the helping, compare on the terms that matter to you: the liability, the reporting, the exit, and the total cost over the life of the agreement, rather than the advertised rate alone.
Complaints go to different places depending on who lent the money. Federally regulated financial institutions' consumer complaints go to the Financial Consumer Agency of Canada, while provinces license and supervise most other lenders. Knowing which regulator oversees the lender helps if something goes wrong.
