Corporate Declaration Affidavit Notarization in Ontario

In Ontario, corporate declarations are often tied to filings with the Ontario Business Registry (OBR) or the provincial government. These affidavits are commonly required when registering a business, updating corporate records, or dissolving an organization. To be legally valid, these declarations must be commissioned by a Notary Public, paralegal, or commissioner of oaths.

When Is a Corporate Affidavit Required?

Corporate declarations may be required when:


  • Submitting a sworn statement to the Ontario Business Registry
  • Filing for business name registration or renewal
  • Reporting changes to registered address or officers
  • Executing dissolution or withdrawal of a business
  • Declaring compliance in tax, employment, or industry filings

Affidavits support these filings by confirming the truth of the information provided under oath.


Ontario Business Registry (OBR) Filings

  • Business Name Registration: Required to open or operate under a business name in Ontario
  • Changes to Registered Information: Must be updated officially with supporting documentation
  • Dissolution or Withdrawal: Requires declarations from directors or officers confirming the decision
  • Authorized Intermediaries: Legal reps or accountants may be authorized to file with supporting affidavits

Tax-Related Filings and Declarations

  • EFF Declarations (Exemptions, Fees, Fines): Required for certain business tax adjustments
  • Federal or Provincial Reporting: Corporate affidavits may support filings with the CRA or Ontario Ministry of Finance

Why Notarization Is Needed

  • Legal Verification: Affidavits provide a sworn, legally enforceable confirmation of corporate data
  • Government Compliance: Most provincial agencies will not accept corporate declarations without proper commissioning
  • Internal Accountability: Ensures that the company officer making the declaration understands its legal impact
