The access you provide depends on whether the filing is with the **Ontario Business Registry (OBR)** or **Corporations Canada**. This guide explains how to find your corporate key, arrange filing access, and keep your personal sign-in details private. Registry access and Canada Revenue Agency (CRA) authorization are separate requirements. Still choosing a business structure? Read [Business Structures in Canada: Sole Proprietorships, Partnerships, and Corporations](https://toroaccounting.ca/blog/business-structures-in-canada-sole-proprietorships-partnerships-and-corporations?hsLang=en). ![immigrant (6)](https://toroaccounting.ca/hs-fs/hubfs/immigrant%20(6).jpg?width=1440&height=810&name=immigrant%20(6).jpg) ## Ontario Corporations: Ontario Business Registry Ontario corporations use the [Ontario Business Registry](https://www.ontario.ca/page/ontario-business-registry) for corporate registry filings. A Company Key is required to establish access and complete transactions, whether you file directly or use an authorized intermediary. ### What Is an Ontario Company Key? Your Ontario Company Key is a unique **9-digit code** assigned to your business. It allows you to link the corporation to your Ontario Business Account or authorize a trusted intermediary, such as your accountant or lawyer, to file on its behalf. ![CorporateKey](https://toroaccounting.ca/hs-fs/hubfs/CorporateKey.jpg?width=474&height=613&name=CorporateKey.jpg) **Keep this key confidential.** It is not your Ontario Corporation Number (OCN), CRA Business Number, corporate tax account number, or Ontario.ca Login password. ### How to Find or Request Your Company Key Start by checking your incorporation or registration correspondence. Ontario sends the key to the official email address when a new entity is registered or incorporated through the OBR. If you cannot find it, you can request it from the ministry at no charge: 1. Visit the [Ontario Business Registry](https://www.ontario.ca/page/ontario-business-registry) and select **Get a company key**. 2. Search using your corporation’s registered name, Ontario Corporation Number, or Business Identification Number (BIN), as applicable. 3. Select your corporation and follow the verification prompts. 4. If the official email address you enter matches the address on file, the key is emailed to that address immediately. 5. If email verification is unavailable or unsuccessful, follow the postal-code option to request delivery to the business address on file, as applicable. When the postal code matches, Ontario’s guide says the key is mailed within **three business days**. Allow additional time for delivery. If the address information does not match, you may be offered additional verification questions. Ontario’s guide says the key will be sent within **five business days** if the ministry verifies the information without discrepancies. For full instructions, see Ontario’s [Company Key request guide](https://www.obrpartner.mgcs.gov.on.ca/onbis/partner/document/pdf/Company%20Key%20Guide). **No longer have access to the email or address on file?** Contact Toro Accounting for help determining the next step. If you cannot recover the key online, contact ServiceOntario at **416-314-8880** or **1-800-361-3223**. ### Do I Need to Link the Corporation to My Own Account First? To manage filings yourself, you need an Ontario.ca Login, an Ontario Business Account, and a Company Key to set up access to your OBR profile. Follow the setup instructions on the official OBR website. If Toro Accounting is filing as your authorized intermediary, we can use your Company Key to establish the delegated authority needed for the agreed services. **You do not need to give us your personal login or password.** ### What to Provide to Toro Accounting If you have engaged us to handle your Ontario registry filings, please provide: - Your corporation’s legal name. - Your Ontario Corporation Number, normally found on your Ontario Certificate of Incorporation or other corporate documents. - Your Ontario Company Key. **Contact us to arrange secure sharing of the key.** Do not include it in a public form, blog comment, or unsecured message. We will confirm any additional authorization or documents required. ## Federal Corporations: Corporations Canada Federal corporate registry filings are handled through Corporations Canada, part of Innovation, Science and Economic Development Canada (ISED). Federal corporations use a **Corporation Key**, which is separate from an Ontario Company Key. ### What Is a Federal Corporation Key? The Corporation Key is a confidential credential used to establish access to your federal corporation and authorize certain transactions. Share it only with people authorized to file on the corporation’s behalf. Once your account is linked to the corporation through Corporations Canada’s access-management tools, you generally do not need to enter the key again for future online filings. Keep it securely: certain transactions submitted by email or mail may still require it. ![Federal Corporate Key](https://toroaccounting.ca/hs-fs/hubfs/Federal%20Corporate%20Key.jpg?width=578&height=771&name=Federal%20Corporate%20Key.jpg) ### Where to Find Your Corporation Key Check these records before requesting a replacement: - The **Corporate Information Sheet** emailed by Corporations Canada on the date of incorporation. - The email receipt for an annual return filed **before September 15, 2021**, if applicable. ### How to Request a Replacement If you cannot locate the key, visit the official [Corporations Canada Corporation Key page](https://www.ised-isde.canada.ca/site/corporations-canada/en/corporation-key). Before requesting a replacement, keep the following in mind: - **The previous key becomes invalid** as soon as a new one is issued. - The replacement is mailed to the registered office address on file by the end of the next business day. Delivery time is additional. - If the address is incorrect or you need the key urgently, call Corporations Canada at **1-866-333-5556** before requesting a replacement. **Replacing the key does not automatically revoke existing access.** Users and registered intermediaries already linked to the corporation remain linked. Review and remove their permissions separately when appropriate. ### How to Arrange Access for Toro Accounting Corporations Canada manages online filing access through the Online Filing Centre and My ISED Account. The correct process depends on your corporation’s existing permissions and the capacity in which your professional representative is filing. 1. Locate your federal corporation number and Corporation Key. 2. Tell us whether the corporation already has a Full Access Manager. 3. Follow our instructions to arrange the appropriate filing access. This may involve signing in through your own My ISED Account, establishing access using the key, or asking the existing Full Access Manager to manage permissions. 4. Share the Corporation Key securely only if our team confirms it is needed. We will confirm the appropriate access arrangement without asking for your personal government sign-in credentials. ### Who Should Be the Full Access Manager? A **Full Access Manager** controls the corporation’s online filing permissions. A director or an authorized agent, such as an officer within the corporation, can hold this role. A registered intermediary acting only as the corporation’s external representative cannot be its Full Access Manager. Registered intermediary organizations have separate access roles. Toro Accounting will confirm the arrangement that applies to your corporation rather than assume a particular intermediary status or permission. For details, review Corporations Canada’s [access-management roles](https://ised-isde.canada.ca/site/corporations-canada/en/about-us/access-management-roles). For a plain-language explanation of corporate responsibilities, read [Shareholder vs Director vs Officer in Canada](https://toroaccounting.ca/blog/shareholder-vs-director-vs-officer-in-canada?hsLang=en). ## Ontario Company Key vs. Federal Corporation Key ### Ontario registry access - **Registry:** Ontario Business Registry. - **Access credential:** Ontario Company Key. - **Account for direct access:** Ontario.ca Login and Ontario Business Account. - **Professional filing access:** Delegated authority for an authorized intermediary. - **Includes CRA authorization:** No. ### Federal registry access - **Registry:** Corporations Canada Online Filing Centre. - **Access credential:** Federal Corporation Key. - **Account for direct access:** My ISED Account. - **Professional filing access:** Applicable filing permissions and access-management roles. - **Includes CRA authorization:** No. **A federal corporation operating in Ontario may need access to both registries.** Federal incorporation does not remove applicable Ontario registration and information-filing obligations. The federal Corporation Key does not replace the Company Key used for the corporation’s Ontario registry profile. ## CRA Authorization Is a Separate Step Access to the OBR or Corporations Canada does not authorize Toro Accounting to deal with the CRA on your behalf. If we will handle your corporation’s income tax, GST/HST, payroll, or CRA correspondence, you must arrange separate authorization for the relevant business accounts. Follow [How to Authorize Toro Financial Inc. as CRA Business Representative](https://toroaccounting.ca/blog/authorize-toro-financial-business-cra-account?hsLang=en). For corporate accounts, use the business authorization process rather than the personal My Account process. If your business is not visible when you sign in, see [How to Add a Business Profile to Your CRA Account](https://toroaccounting.ca/blog/business-profile-cra?hsLang=en). ## Your Access Checklist Start by giving us your corporation’s **legal name, jurisdiction of incorporation, and corporation number**. We will then confirm what else is needed: - **Ontario filings:** Your Ontario Corporation Number and Company Key. - **Federal filings:** Your federal corporation number, any required access-management authorization, and the Corporation Key if requested. - **Filings in both registries:** The relevant Ontario and federal details. **Never share your personal passwords or authentication codes.** This includes your Ontario.ca Login, My ISED Account, GCKey, CRA, personal email, and online banking credentials, as well as one-time sign-in codes. Corporate keys may be shared securely with trusted professionals authorized to file for your corporation. Personal sign-in credentials must remain private. ## What Happens After Access Is Set Up? Once the required authorizations are in place, Toro Accounting can assist with the services covered by your engagement, which may include: - Corporate annual returns and applicable registry updates. - Director, officer, and registered office information updates, where applicable. - Corporate recordkeeping and compliance support. - T2 corporate income tax returns. - GST/HST compliance and CRA correspondence. - Bookkeeping and accounting. Registry access does not replace the corporate approvals required for a filing. We will let you know if additional permissions, documents, or professional advice are needed.

See [How to Make a T2 Corporate Tax Payment Using the CRA’s My Payment Service](https://toroaccounting.ca/blog/how-to-make-a-t2-corporate-tax-payment-using-the-cras-my-payment-service?hsLang=en). If the corporation is no longer operating, do not simply stop filing.
