Starting a Small Business in Ontario: Legal Checklist

A strong business foundation is easier to build before money, intellectual property, and responsibilities become complicated. Legal, accounting, tax, insurance, and regulatory advice often need to work together.

Choose and document the structure

  • Compare the practical implications of operating alone, with partners, or through a corporation.
  • Document ownership, contributions, decision-making, compensation, and exit arrangements.
  • Check business-name, registration, licence, permit, and industry requirements.
  • Keep business money and records separate from personal activity.

Use clear agreements

  • Define scope, price, payment, changes, delays, ownership, confidentiality, and termination.
  • Match customer and supplier promises to what the business can actually deliver.
  • Review leases and major commitments before signing.
  • Use employment or contractor agreements that reflect the real relationship.

Plan for risk and growth

Consider privacy, records, insurance, cybersecurity, taxes, succession, and dispute procedures early. Revisit the legal structure and contracts as the business adds owners, staff, locations, financing, or new products.

Templates can be a starting point, but important agreements should reflect the business, the transaction, and current Ontario law.
