Most CSBFP guides discuss the personal guarantee as if it's a single-person question. In practice, many CSBFP borrowers are corporations with two or more principals — business partners who co-founded the company, spouses who co-own the business, or investor-operators with different ownership percentages.
When multiple shareholders are involved, the guarantee structure, the documentation requirements, and the lender's assessment of the application all change. This post covers how it works.
The statutory guarantee structure
CSBFP's personal guarantee is governed by the Canada Small Business Financing Act and is statutory — meaning it is defined by the program rules, not by negotiation between the lender and the borrower. The maximum guarantee amount per person is 25% of the original loan amount.
This is not a negotiating position. A lender cannot require a guarantee higher than 25% per principal. It is also not the aggregate — it is per individual guarantor.
Single guarantor: If one person owns 100% of the corporation and signs the personal guarantee, that person is on the hook for up to 25% of the original loan. On a $400,000 CSBFP loan, the maximum personal guarantee exposure is $100,000.
Two guarantors: If two people each sign the personal guarantee, each person's maximum exposure is 25% of the original loan. On a $400,000 loan, each person's maximum exposure is $100,000. The guarantee is not split between them — each person is guaranteeing up to 25% independently.
The government's guarantee behind the lender (the 85% government backstop on the lending risk) is separate from the personal guarantee to the lender. Do not confuse these two guarantees — one is the lender's guarantee from the federal government; the other is the borrower's personal guarantee to the lender.
Who must sign the guarantee?
The CSBFP rules require the personal guarantee to be signed by each person who is a director, officer, or shareholder of the borrowing corporation — or by the partners in a partnership. In practice, lenders typically require the guarantee from:
- All shareholders who own 25% or more of the corporation: Most lenders apply a 25% ownership threshold — if you own at least 25% of the shares, you sign the guarantee. Some lenders apply a lower threshold (10% or 20%) for their own risk management purposes, but 25% is the program's own ownership threshold for the business eligibility test.
- All directors and officers: Regardless of ownership percentage, some lenders require directors and officers to sign. This is common for lenders who want the personal engagement of everyone in a management role.
- Guarantors above the threshold: Some lenders also require spouses of principal shareholders to sign, particularly in provinces where matrimonial property law creates a community property interest in the guarantor's assets.
Minority shareholders below the threshold: A 10% shareholder who is not a director or officer of the company is typically not required to sign the personal guarantee. However, lenders vary on this — ask directly which principals will be required to sign.
How ownership percentage affects the application
A shareholder's ownership percentage affects the application in two ways:
1. The ownership documentation requirement. The lender needs to confirm who owns what percentage of the corporation. For a two-person corporation, this is a share register showing, for example, "Jane Smith: 60 common shares (60%), John Smith: 40 common shares (40%)." For corporations with multiple share classes or complex ownership through holding companies, the lender will trace through the ownership chain to identify the ultimate individual owners.
2. The guarantor assessment. Each guarantor's personal credit and personal financial position is assessed individually. If one of the two principals has a materially stronger personal credit profile than the other, the lender's comfort with the personal guarantee is affected. A file where one principal has a clean 780-score credit history and the other has a recent bankruptcy looks different to a lender than a file where both principals have clean histories — even if both are signing the same 25% guarantee.
The documentation each principal must provide
Each person who is required to sign the personal guarantee must provide a full set of personal documentation. There is no shortcut for a minority shareholder or a silent partner — if they are required to sign, the lender needs their complete file:
- Two pieces of government-issued identification
- Personal Statement of Affairs (personal net worth statement)
- 2–3 years of personal T1 General returns
- Personal Notices of Assessment (CRA) for the same years
- 12 months of personal bank statements from the primary account
- Signed personal credit authorization
This documentation requirement is sometimes a surprise to multi-principal businesses. A 40% shareholder who expected to be a passive investor discovers at the application stage that they need to provide their personal tax returns, their personal credit history, and their personal net worth. Plan for this before submitting the application.
Structures with holding companies
Many small business owners operate through a holding company ("HoldCo") structure: the HoldCo owns the shares of the operating company ("OpCo"), and the individual owners own the HoldCo. The CSBFP loan is made to the OpCo (the business that owns or uses the eligible assets).
For CSBFP guarantee purposes, the lender traces the ownership chain to the ultimate individual owners — the natural persons. If Jane Smith owns 100% of HoldCo, and HoldCo owns 100% of OpCo (the CSBFP borrower), Jane Smith is treated as the principal and guarantor for CSBFP purposes.
For a two-person HoldCo structure — Shareholder A owns HoldCo A (60%) and Shareholder B owns HoldCo B (40%), and HoldCo A and HoldCo B together own OpCo — the lender will require documentation from both Shareholder A and Shareholder B as the ultimate principals.
Note for lenders and CPA advisors: Some lenders are less familiar with multi-layer corporate structures and may ask for additional documentation to confirm the ownership chain. Having a clean, one-page ownership chart prepared in advance (showing each HoldCo, its individual owner, and the percentage ownership of OpCo) saves time in the credit review.
Practical considerations for co-founders and business partners
Unequal ownership: A 70%/30% split is common in co-founded businesses. Both partners are typically required to sign the CSBFP guarantee. Both receive the benefit of the 25% statutory cap on their individual guarantee. The minority partner (30%) is often surprised to learn that their guarantee exposure is the same dollar amount as the majority partner's — both are guaranteeing 25% of the loan amount, not 25% × their ownership percentage.
Inactive or silent partners: If a shareholder is on the share register but is genuinely passive — no directorship, no officer role, owns less than 25% — lenders may not require their guarantee. But passive ownership above 25% typically still triggers a guarantee requirement at most lenders. If a significant minority shareholder does not want to participate in the guarantee, consider restructuring the ownership before applying.
Spouses as co-owners: Many family businesses have spouses as co-shareholders for estate planning or income-splitting purposes. If the spouse is a director or officer, or owns 25%+, the lender will require full documentation from both spouses. Confirm this structure with your accountant before applying — rearranging share ownership shortly before a credit application can raise questions.
New partner being bought in: If one partner is buying out another (or a new partner is coming in) using CSBFP financing, the structure is a partner buyout — a specific CSBFP use case with its own documentation requirements (share purchase agreement, valuation, and independent legal advice for the selling party).
How the guarantee works at default
If the CSBFP loan goes into default and the lender calls on the personal guarantee, each guarantor is liable up to 25% of the original loan amount — regardless of whether other guarantors are solvent or available. The guarantee is several, not joint-and-several in the usual commercial sense. Practically, a lender may pursue all guarantors simultaneously or in sequence depending on asset availability.
The 25% cap is on the original loan amount, not on the outstanding balance. On a $400,000 CSBFP loan, the maximum personal exposure is $100,000 per guarantor — even if the loan has been partially repaid and the outstanding balance at default is only $200,000.
