New Corporation or Existing One? The Founder’s Guide to Choosing Your Path for Growth, Taxes, and Liability.
If your spouse and her friend are planning to start a business together in Ontario, one of the first decisions is whether to reuse your existing corporation or start a new one. This guide outlines all options, integrates the key checklists, and helps you decide what’s right for your situation.
Option 1 — Reuse the Existing Corporation
· When It Makes Sense
– The existing corporation is fully compliant and up to date — annual returns, T2 corporate tax, GST/HST, and payroll filings are all current.
— No outstanding liabilities, lawsuits, or CRA debts.
— You want to save on setup time and use existing CRA business numbers and banking.
Advantages
– Faster to activate — no new incorporation process.
— CRA accounts, bank relationships, and vendor IDs already exist.
— Lower short-term administrative costs.
Risks & Cautions
– You inherit all past liabilities (tax, legal, or reputational).
— A change of control (adding new shareholders) can trigger a deemed year-end, creating an extra tax filing and potentially eliminating loss carry-forwards.
— Old share structures may not suit a new partnership.
Ontario-Specific Execution Checklist
1. Corporate Health Review: Obtain a Corporate Profile Report, ensure compliance under OBCA, verify CRA accounts (T2, GST/HST, WSIB).
2. Cap Table & Share Structure Reset: Amend articles if needed, create proper shareholders’ agreement.
3. Governance Updates: Pass resolutions to change directors/officers, update CRA and banks.
4. Tax Year Planning: Time transition near fiscal year-end, file T2 returns.
5. Legal & Insurance Review: Update policies, ensure contracts align with new ownership.
Option 2 — Keep the Existing Corporation and Treat the Friend as a Contractor
· When It Makes Sense
– You want to retain ownership while collaborating on a project.
— The friend prefers to invoice as a contractor instead of becoming a shareholder.
Advantages
– Simple setup — no restructuring.
— Friend can operate independently.
— Easy to end or modify the relationship later.
Risks
– CRA could reclassify the arrangement as employment or partnership.
— Contractor may expect profit-sharing or equity later — set boundaries early.
Ontario-Specific Execution Checklist
1. Written Contractor Agreement: Define scope, payments, IP ownership.
2. Avoid Implied Partnership: Maintain branding in your corporation’s name.
3. Tax & Compliance: Register HST if income > $30,000.
4. Documentation: Keep invoices and payment records.
Option 3 — Incorporate a Brand-New Company (Most Recommended)
· When It Makes Sense
– You want a clean slate, free from prior liabilities.
— The business will be co-owned or expanded with investors.
— You expect to apply for funding or build a sellable asset.
Advantages
– No legacy risks.
— Can design share structure from the start.
— Clean record for CRA and due diligence.
Ontario-Specific Incorporation Checklist
- Incorporation Setup: NUANS search, file Articles under OBCA, issue shares, maintain minute book.
- Founders’ Documents: Draft shareholders’ and IP assignment agreements.
- CRA & Provincial Registrations: Obtain BN, register GST/HST, payroll, WSIB.
- Banking & Operations: Open accounts, set up accounting software.
- Insurance & Compliance: Obtain insurance, file first annual return.
- Future Planning: Structure for LCGE eligibility.
Final Advice for Ontario Business Owners
– Keep records organized — CRA expects updated minute books and filings.
— Avoid commingling personal and business funds.
— Review WSIB, insurance, and taxes annually.
— Structure ownership with future growth in mind.
Bottom Line
For two founders starting fresh in Ontario, forming a new corporation is generally the safest, cleanest, and most scalable route. It avoids legacy issues, supports proper equity allocation, and sets you up for future growth or sale.
