Amalgamating under the Ontario Business Corporations Act (OBCA) combines two or more companies into one continuous entity. Filing Articles of Amalgamation (Form 4) through the Ontario Business Registry currently requires a provincial government fee of $250 CAD when completed online.
Simplifying your corporate structure can save you thousands of dollars in accounting and administrative costs each year. Whether you are streamlining operations in Toronto, consolidating real estate holding companies in Mississauga, or merging family businesses in London, an amalgamation is a powerful legal tool.
In Ontario, a “short-form amalgamation” is the fastest and most cost-effective way to merge companies that are already related (such as a parent and a subsidiary). Unlike a complex long-form amalgamation, which requires formal shareholder agreements and extensive financial reviews, the short-form process is designed for simplicity. This guide outlines the proper steps to successfully amalgamate private corporations under the OBCA. 📍
Step-by-Step Process for Amalgamation in Ontario
Merging two corporate entities is a precise administrative process. The law requires you to file specific documents with the Ontario government to ensure the new, single corporation correctly inherits all the assets, liabilities, and contracts of its predecessors.
Step 1: Determine the Type of Short-Form Amalgamation
Before drafting any documents, you must determine how the companies are related. A vertical short-form amalgamation occurs when a parent company merges with one or more of its wholly-owned subsidiaries. 📈
Alternatively, a horizontal short-form amalgamation happens when two or more subsidiary companies, wholly owned by the exact same parent corporation, merge together. Identifying the correct relationship dictates the specific wording required for your corporate resolutions.
Step 2: Draft and Sign Directors’ Resolutions
In a short-form amalgamation under the OBCA, you generally do not need a formal shareholder vote. Instead, the directors of each amalgamating corporation must sign written resolutions approving the merger.
These resolutions confirm that the amalgamation will not make the new company insolvent, nor will it defraud current creditors. The directors must also clearly state whether the new entity will adopt the corporate name and articles of the parent company (in a vertical merger) or one of the subsidiaries (in a horizontal merger).
Step 3: Prepare the Articles of Amalgamation (Form 4)
Once the resolutions are signed, you must prepare the Articles of Amalgamation. This legal document acts as the birth certificate for your newly merged company. 📄
The Articles will list the names of the amalgamating corporations, their Ontario Corporation Numbers (OCN), and the registered head office address. If you are a business owner in Ottawa or Hamilton, ensure the registered address is entirely accurate, as the Canada Revenue Agency (CRA) and provincial ministries will send official mail there.
Step 4: File via the Ontario Business Registry
Finally, the completed Articles of Amalgamation must be filed electronically through the Ontario Business Registry (OBR). As of May 2026, most corporate law firms prefer to handle this filing online to ensure immediate processing.
Once approved, the province will issue a Certificate of Amalgamation. It is vital to place a copy of this certificate, along with the newly adopted by-laws and directors’ resolutions, into your updated corporate minute book.
How Much Does it Cost in Ontario?
Budgeting for an amalgamation involves both mandatory provincial fees and professional service fees. Consolidating early can help avoid double the accounting fees at tax season. 💵
- Provincial Government Filing Fee: The Ontario government currently charges $250 CAD to file Articles of Amalgamation electronically. If filed via paper mail, the fee is $330 CAD.
- NUANS Name Search (If applicable): If the amalgamated corporation is taking on an entirely new name, a corporate name search report costs approximately $15 CAD to $30 CAD.
- Corporate Lawyer Fees: Having an Ontario corporate lawyer draft the resolutions, prepare the minute book, and file the amalgamation typically costs between $1,500 CAD and $3,500 CAD, depending on the complexity of the share structure.
How Long Does the Process Take?
Timelines depend heavily on how organized your current minute books are and whether your corporate taxes are up to date. ⌛
If the minute books for both companies are fully updated and no complex legal clean-up is required, an Ontario lawyer can generally complete a short-form amalgamation in 1 to 2 weeks. The actual provincial filing through the Ontario Business Registry is typically processed within 24 hours when submitted online.
Frequently Asked Questions (FAQ)
What happens to the debts of the old corporations?
Under the OBCA, the newly amalgamated corporation automatically inherits all the assets, liabilities, obligations, and civil lawsuit risks of the merging companies. You cannot use an amalgamation to erase business debts.
Do we get a new Business Number from the CRA?
Generally, if a parent and subsidiary amalgamate vertically, the CRA allows the new entity to retain the Business Number of the parent corporation. However, you must formally notify the CRA of the amalgamation within 30 days of receiving your Certificate.
Can an Ontario corporation amalgamate with a federal corporation?
Not directly. Before you can merge them, one of the companies must be “continued” into the other’s jurisdiction. For example, the federal company would first need to be imported into Ontario under the OBCA, or the Ontario company exported to the federal system, before amalgamation can occur.
Do employees have to sign new employment contracts?
Usually, no. Employment law in Ontario generally views an amalgamation as continuous employment. The new corporate entity assumes all existing employment contracts and recognizes the employees’ past years of service for the purpose of severance calculations.
