Free Renewal Reminder Service
Sole Proprietorships, General Partnerships, and Trade Names renew every 5 years. Miss the renewal window and your registration expires. We track your renewal date and email free reminders ahead of each deadline so you never lose your registration.
Practical Guidance For Managing Your Amendment
Forward your updated registration to your bank, lenders, and key vendors. Address changes especially require updating cheque-issuing systems and vendor profiles.
Update your business address with the CRA via My Business Account. Address changes affect HST, payroll, and corporate tax correspondence.
If you have employees, update the WSIB and any other provincial accounts (Health Tax, EHT) with your amended business information.
If you have business insurance, professional licences, or municipal permits, notify each provider of the address or partner change to keep coverage active.
Update your website, business cards, invoices, contracts, and Google Business Profile with the amended details. Keeps your customer-facing presence consistent.
Sole Proprietorships, General Partnerships, and Trade Names must be renewed every 5 years. Our free reminder service emails you ahead of the renewal deadline so you don't lose your registration.
Order an Ontario Business Name Search to confirm your amendment is reflected on the public OBR record. Useful for banks, lenders, and contracts.
If business activities expand, partners change, or addresses move, file additional amendments as needed. Keeping your registration current keeps you compliant under the Business Names Act.
Amendable items vary by registration type. Find your registration type below to see what we can update.

CANNOT DO
A Business Name Registration (formerly Master Business Licence) under the Business Names Act does not allow a change of the business name. To change the name of your registration, you must complete a new registration under the desired name. The old registration can be cancelled separately if no longer needed.
CANNOT DO
Under the new OBR system, changes to a registration and renewal must be completed as two separate filings. If you also need to renew your registration, amend the details first, then complete the renewal application as a separate transaction. We handle both in your account.
Common questions about amendments, Company Key, OBR processing, and renewal cycles
The OBC service fee for an amendment is $109.99. If you don't know your BIN, we offer a registry search for $10.00 + HST. The Company Key (mandatory since February 1, 2025) can be requested as part of your filing at a 27% discount. Total cost is typically $124.29 (amendment + HST), with optional add-ons depending on what's needed.
Yes. Effective February 1, 2025, all Ontario business registry filings, including amendments to Sole Proprietorships, General Partnerships, and Trade Names, require a Company Key. The Company Key is a 9-digit identifier issued by the Province of Ontario. If you don't have one, we can request it as part of your filing at a 27% discount, though this may add 1-2 business days to processing time.
No. A Business Name Registration (formerly Master Business Licence) under the Business Names Act does not allow a change of the business name. To change your name, you must complete a new registration under the desired name. The old registration can be cancelled separately if no longer needed. We can help with both the new registration and the cancellation as separate filings.
No. Under the new OBR system, changes to a registration and renewal must be completed as two separate filings. If you also need to renew, amend the details first, then complete the renewal application as a separate transaction. We can handle both for you, just place each as a separate order. Our free renewal reminder service helps you track upcoming renewals.
OBC files amendments same-day if ordered before 3pm EST. OBR processing typically takes 1-3 business days from submission. If you needed us to obtain the Company Key as part of the bundle, add 1-2 business days. Updated registration is emailed directly to you once OBR processing is complete.
Sole Proprietorship amendments can update: business address, owner address, business activity (NAICS code), email address. Some changes have specific requirements, our team confirms eligibility during review.
General Partnership amendments can update: business address, partner addresses, business activity (NAICS code), email address, and add or remove partners (as long as 2 or more partners remain after the change). If reducing to a single partner, a new Sole Proprietorship registration is required, partnerships require 2+ partners.
Trade Name amendments can update: business address and business activity (NAICS code). The corporation behind the Trade Name must remain in good standing for amendments to be processed.
Sole Proprietorships, General Partnerships, and Trade Names must be renewed every 5 years under the Ontario Business Names Act. Failure to renew within the 5-year window means your registration expires and you'd need to register again from scratch. Our free renewal reminder service is automatically activated when you amend, you'll receive email reminders ahead of each renewal deadline.
This amendment filing is for non-corporate registrations only (Sole Proprietorship, General Partnership, Trade Name). If you have a corporation and need to update the corporate address or directors, file an Ontario Notice of Change instead. If you need to change the corporate name or share structure, file Articles of Amendment (see below).
