How to Set Up a Holdco in Ontario — 8 Steps (2026)

A Holdco (holding corporation) sits above your operating company (Opco) and holds shares, retained earnings, or investments. Owner-managers use Ontario Holdcos to move safe-income out of the Opco tax-deferred, insulate accumulated capital from operating creditors, and open estate-freeze / income-splitting doors. This 8-step guide walks the full setup — including the corporate lawyer touchpoints and CPA touchpoints — using 2026 Ontario and federal rules.

1. Step 1: Define the purpose before you incorporate

   Write down why the Holdco exists — creditor insulation, safe-income parking, estate freeze runway, real estate investment, or all four. The purpose drives share-class design, articles of incorporation clauses, and shareholders’ agreement language. Ontario Holdcos formed without a written purpose typically get restructured within three years, wasting the original s.85 elections. Confirm you actually need a Holdco by modelling after-tax outcomes against a bare Opco with a properly funded retirement compensation arrangement or IPP.

2. Step 2: Choose federal (CBCA) or Ontario (OBCA) jurisdiction

   CBCA (federal, incorporated under the Canada Business Corporations Act) allows you to operate anywhere in Canada with one filing. OBCA (Ontario, under the Business Corporations Act) is cheaper and simpler if you never operate outside Ontario. Both allow non-resident directors post-2021 amendments. Most Ontario owner-managers pick OBCA for a pure Holdco. Name search (NUANS) is required for a named corporation; a numbered corp skips this. Filing is done via the Ontario Business Registry or Corporations Canada online.

3. Step 3: Design the share structure with your lawyer

   A defensible Holdco share structure typically has: Class A common voting participating (owner), Class B common voting participating (spouse/kids over 25, subject to TOSI), Class C non-voting participating, and one or more classes of retractable, redeemable preferred shares used later for s.85 rollovers or estate freezes. Draft the articles to include the price-adjustment mechanism, redemption schedule, and dividend priorities. The lawyer prepares the articles of incorporation; the CPA reviews the share terms for tax neutrality.

4. Step 4: File articles of incorporation and get certificates

   File Form 1 (OBCA) or the equivalent federal form. Ontario filing fee is $300 online. Include the initial director(s), registered office address, and share class attributes. The certificate of incorporation issues within one business day online. Save the certificate and articles as the foundation of the minute book. Do not skip named-corp NUANS if you plan to use the name commercially — reserving via numbered corp only, then rebranding later, requires a name-change filing.

5. Step 5: Register CRA business number and program accounts

   Once incorporated, register a Business Number (BN) with CRA. The Holdco needs an RC (corporate tax) account automatically. Only register RT (HST/GST) if the Holdco will earn taxable supplies — most pure Holdcos do not. Register RP (payroll) only if you plan to run salary through the Holdco. Registering unneeded accounts creates nil-return filing obligations. Use the CRA “Register a business” service or via your CPA’s Represent a Client portal.

6. Step 6: Open a corporate bank account and separate books

   Bring the certificate of incorporation, articles, initial director resolutions, and BN to your bank. Open one operating account and one investment account. Never commingle Holdco funds with personal or Opco funds — piercing the corporate veil is one CRA reassessment away when records are sloppy. Set up cloud accounting (QBO/Xero) with a separate file for the Holdco, distinct chart of accounts, and monthly bank reconciliations from day one.

7. Step 7: Execute the Opco → Holdco share transfer under Section 85

   The classic setup: transfer your Opco common shares to the Holdco under s.85 in exchange for Holdco preferred shares (equal to Opco FMV) plus Holdco common shares for future growth. File Form T2057 for the election. Refresh safe-income on hand (SIOH) so future intercorporate dividends flow tax-free under s.55(2). This step is where most self-directed Holdco setups fail — engage a CPA to file the T2057 and a lawyer to draft the transfer agreement, share subscriptions, and updated minute book.

8. Step 8: Draft the shareholders’ agreement and ongoing compliance calendar

   A shareholders’ agreement is not filed publicly but binds all Holdco shareholders on transfer restrictions, buy-sell triggers, valuation, and dispute resolution. Even a sole-shareholder Holdco benefits from a founder-departure protocol tied to the estate plan. Diarize the T2 return (due 6 months after fiscal year end, payment due 2 or 3 months after), Ontario annual return (via CRA T2 attachment since 2021), minute book updates, and directors resolutions for any material transactions. Missed Ontario annual returns can result in involuntary dissolution.

Frequently Asked Questions

How much does it cost to set up a Holdco in Ontario in 2026?

Government filing fee is $300 OBCA online. Lawyer articles + minute book: $1,500-$3,500. CPA structuring memo + s.85 election: $2,500-$6,000 depending on complexity. Total realistic budget: $4,300-$9,800 for a compliant Holdco+Opco reorganization.

Can a Holdco hold my house?

Legally yes, but the tax cost is high — you lose the principal residence exemption, shareholder benefits under s.15(1) apply if you occupy rent-free, and land transfer tax may trigger on transfer. Almost never advisable. Personal-use real estate stays in personal name; income-producing real estate can go in a Holdco.

What is safe-income on hand and why does it matter?

Safe-income on hand (SIOH) is the portion of a corporation’s retained earnings that has been taxed and can support a tax-free intercorporate dividend under s.55(2). If a dividend exceeds SIOH, CRA can recharacterize it as a capital gain. Calculate and document SIOH before every material Opco-to-Holdco dividend.

Do I need to file HST for my Holdco?

Only if the Holdco makes taxable supplies (rental of commercial real estate, consulting, etc.). A pure investment/passive Holdco does not need an RT account. Registering unnecessarily forces nil-return filings and audit exposure.

Should my spouse be a shareholder of the Holdco?

Under the Tax on Split Income (TOSI) rules effective since 2018, dividends to family members generally attract top-bracket tax unless the recipient meets an “excluded amount” test — 20+ hours per week in the business, ownership of 10%+ voting shares held 5+ years, or age 65+ retirement carve-out. Model the outcome with your CPA before issuing shares to family.

Common pitfalls in setting up an Ontario holdco

• Missing the association rules. The Holdco and Opco become associated corporations under ITA s. 256 the moment Holdco owns 25%+ of Opco voting shares. Associated corporations share the $500,000 federal small business deduction (SBD) limit — plan the allocation via Schedule 23.
• Ignoring the AAII deemed grind. Passive investment income above $50,000 in the associated group starts grinding the SBD by $5 for every $1 of AAII, fully eliminated at $150,000 AAII. Model this before parking retained earnings in Holdco.
• Non-arm’s length share issuance without valuation. The initial Holdco share issuance to individuals related to Opco shareholders must be supported by fair market value evidence, or CRA can invoke ITA s. 15(1) benefit rules on the discounted purchase.

Forms, filings, and deadlines

Incorporation is via Ontario Business Registry (Ontario Business Corporations Act) or federal Corporations Canada (CBCA). Ontario incorporation costs $300 online; federal costs $200. The corporation must register for a Business Number (BN) with CRA, and file its first T2 within six months of fiscal year-end. Add: RC1 Business Number Request, Schedule 23 (Agreement Among Associated Canadian-Controlled Private Corporations to Allocate the Business Limit), Schedule 50 (Shareholder Information), and Schedule 7 (Aggregate Investment Income / SBD Calculation). CRA guidance: Income Tax Folio S4-F3-C1 and IT-64R4 (Corporations: Association and Control).

Worked example — Holdco receiving eligible dividend

Opco pays a $100,000 eligible dividend from its general rate income pool (GRIP) to Holdco. Because both are Canadian corporations and Holdco owns 100% of Opco (connected), s. 112(1) deduction applies: Holdco reports $100,000 income under s. 82(1) and deducts $100,000 under s. 112(1) — net corporate tax nil. Refundable Part IV tax under s. 186 does NOT apply here (Opco is connected, not a portfolio investment). Holdco can then re-invest the $100,000 in passive investments held by Holdco (not Opco), keeping Opco’s AAII below the $50,000 SBD grind threshold.

Worked example — Opco vs Holdco small business deduction

Opco earns $650,000 active business income (ABI). Holdco earns $10,000 passive interest income. Associated group’s federal SBD limit is $500,000. Without allocation, both may claim, blowing the cap. Schedule 23 files allocate $500,000 to Opco, nil to Holdco. Opco pays 12.2% federal + Ontario 3.2% = 15.4% combined on the first $500,000 ABI; remaining $150,000 ABI taxed at general rate (15% + 11.5% = 26.5%).

Worked example — creditor protection use case

Opco carries operational liability risk (lawsuit exposure). Retained earnings inside Opco are exposed. Regularly stripping RE via tax-free dividends to Holdco (s. 112(1)) parks the cash safely in Holdco, protected from Opco creditors. Combined with a spousal trust or family trust structure, this can extend LCGE eligibility to family beneficiaries — see the LCGE pillar linked above.
