Related-Party Transactions in a Canadian Corporation: Paper That Has to Exist

Loans between related companies, rent paid to a shareholder’s property company, management fees from Opco to Holdco — none of that is exotic. What gets expensive is doing the money move without the paper that shows who owed whom, for what, and on what terms. Related-party transactions need agreements and contemporaneous records, not a balancing entry invented at filing time. Education only.

What “related party” means in practice

For owner-managers, “related” usually means people or entities not dealing at arm’s length: the same shareholders, a Holdco and its Opco, a spouse’s company, or a corporation that rents from you personally. The legal tests are technical. The practical point is simpler: when the other side is not independent, CRA and buyers expect proof the arrangement was real, authorized, and recorded when it happened — not reconstructed years later.

Three transaction types that need paper

1. Intercompany and shareholder loans

Cash advances between related corporations, or between a corporation and a shareholder, need an origin story: who advanced what, on what date, with what repayment terms, and whether interest was intended. A ledger balance alone is not a loan agreement. Bank evidence, a short written note or agreement, and consistent book entries keep the trail usable when someone asks why the balance exists.

Shareholder loan balances that grew without a plan are a common cleanup file: shareholder loan review. Do not wait for a T2 draft to invent the story of last year’s advances.

2. Rent and use of property

When the corporation occupies space owned by a related person or entity, rent should have a basis you can explain: premises, period, amount, and invoices or transfers that match the books. “We always paid about this much” is not contemporaneous documentation. A lease or rental understanding, invoices, and bank trails that line up with the ledger are the minimum that survives a later look.

3. Management fees and shared services

Fees from one related corporation to another for management, admin, or shared services need more than a year-end journal. What services were provided? Who authorized them? What amount was charged, and when was it invoiced and paid? Empty management-fee entries that appear only to move income between entities are a classic soft spot. If the service was real, the paper should look like a real service relationship — terms, invoices, and payment history.

What “contemporaneous” actually requires

Contemporaneous means the documents and entries exist around the time of the transaction, not in a scramble before an audit or a sale. A useful package for each material related-party arrangement usually includes:

• A written agreement, board or shareholder authorization where the corporation’s rules require it, or at least clear terms captured when the arrangement started.
• Invoices or statements that match the period and the amount booked.
• Bank evidence of payment or advance — not only a journal entry.
• Ledger accounts that stay consistent with the story (loan vs expense vs distribution).
• GST/HST treatment recorded the way your advisors set it — remittance timing habits: GST/HST remittance timing.

Stop when each material related-party line on the books has a document trail or a named gap. Dumping unsorted PDFs into a folder labelled “intercompany” is not documentation.

A short order of work

1. List the related parties — people and entities that routinely deal with the corporation (Holdco, Opco, shareholder landlords, sister companies).
2. List the money moves — loans, rent, fees, cost shares, asset sales or transfers for the period you care about.
3. Match paper to each move — agreement or authorization, invoice, bank trail, book entry. Note gaps honestly.
4. Fix going forward — new arrangements get terms and invoices at the start; old gaps get a documented cleanup plan with advisors, not a silent plug.
5. Fold into filing readiness — related-party packs belong with the T2 package, not as an afterthought: corporate T2 filing readiness.

That sequence does not promise that every historical fee will be accepted or that every loan will be recharacterized favourably. It keeps the next conversation tied to evidence.

What usually breaks the file

• Year-end management fees with no invoice, no service description, and no payment until someone needs a deduction.
• Rent paid to a related landlord with no lease terms and amounts that change without a paper trail.
• Intercompany advances labelled “loan” in conversation and “expense” in the books — or the reverse.
• Verbal “we’ll sort it later” between related companies that never gets sorted.
• Treating related-party cleanup as a one-line adjusting entry with no supporting pack for the return or for a buyer.

What this article will not do

It will not set your arm’s-length price from a webpage. It will not tell you whether a specific fee, rent, or loan is deductible or recharacterizable on your facts. It will not claim fixed audit results or assessments, or deal diligence clearance. Those answers belong to your documents and qualified advisors reviewing the actual file.

When a structured consult helps

Quiet related-party arrangements with written terms, invoices, and matching books often need only routine maintenance. Files with unexplained intercompany balances, fees invented at year-end, rent without terms, Holdco/Opco cash without a loan story, or a coming sale or CRA review need an ordered pass: what moved, who authorized it, what paper exists, and what gaps to close next. Help means process quality — facts, gaps, sequenced next steps — not a promised tax or deal result. Related lanes: corporate tax planning and corporate creation and structuring.

FAQ

Do we need a formal contract for every related-party payment?

Not every small reimbursement needs a fifty-page agreement. Material loans, rent, and recurring management fees need terms you can show — written understanding, authorization, invoices, and bank trails that match. Size and recurrence raise the bar.

Can we fix missing paper at year-end?

You can improve records going forward and document what actually happened. Inventing agreements after the fact to support a number you already booked is a weak story. Say what is real; close gaps with advisors.

Are related-party transactions automatically a problem?

No. They are common in private Canadian structures. The problem is unsupported or inconsistent documentation — not the existence of a related counterparty.

Is this tax advice?

No. General education only. Your facts and qualified advisors control. Your facts and file control.

Closing

Treat related-party loans, rent, and management fees as arrangements that need paper when the money moves — not when the T2, the bank, or a buyer asks. Clear terms, invoices, bank evidence, and ledger consistency are the baseline. That keeps related-party transactions corporation Canada documentation tied to what actually happened, not to a reconstruction under pressure.
