Section 87 Amalgamations in Canada: Merging Corporations Tax-Free

18 Jun 2026 4 min read No comments Money, Taxes & IP Canada
🤝

Section 87 of the Income Tax Act allows two or more Canadian corporations to merge into a single entity on a tax-deferred basis. This legal amalgamation seamlessly combines assets, liabilities, and tax histories without triggering capital gains taxes or disrupting business operations.

When businesses grow, acquire competitors, or seek to streamline their internal structures, they often end up with multiple corporations operating under one umbrella. Maintaining separate corporate entities means paying for multiple T2 corporate tax returns, managing separate payrolls, and dealing with unnecessary administrative bloat. In Canada, the most effective way to combine these entities is through a corporate amalgamation.

If you were to simply sell the assets of one company to another, the Canada Revenue Agency (CRA) would normally tax the transaction as a deemed disposition, triggering heavy capital gains taxes. To encourage business efficiency, Section 87 of the Income Tax Act provides a “rollover” mechanism. As long as specific continuity rules are met, two or more taxable Canadian corporations can legally fuse together to form a new corporation, rolling all assets and tax accounts over completely tax-free.

Step-by-Step Process for a Corporate Amalgamation

Whether you are merging two tech startups in Vancouver or combining real estate holding companies in Toronto, amalgamations require precise legal and accounting coordination. The process generally follows these steps.

Step 1: Choosing Short-Form vs. Long-Form

Your corporate lawyer will first determine which type of amalgamation applies. A “short-form” amalgamation is a simplified process used when a parent company merges with its wholly-owned subsidiary (vertical), or when two subsidiaries owned by the exact same parent merge together (horizontal). If the merging companies are owned by different people or have different share structures, you must use the “long-form” process, which requires a detailed Amalgamation Agreement.

Step 2: Drafting the Amalgamation Agreement (Long-Form)

If proceeding with a long-form amalgamation, your legal team must draft an agreement outlining the terms of the merger. This includes how the shares of the old companies will be converted into shares of the new company, who the new directors will be, and the new corporate bylaws. This agreement must be formally approved by a special resolution of the shareholders of each amalgamating corporation.

Step 3: Filing Articles of Amalgamation

Once approved, the lawyer files Articles of Amalgamation with the relevant government registry (e.g., Corporations Canada or a provincial registry). It is critical that all merging companies are governed by the same jurisdiction (e.g., both must be Ontario corporations, or both federal). If they are from different provinces, one must first be “continued” (moved) into the other’s jurisdiction before they can legally merge. Upon filing, a Certificate of Amalgamation is issued, officially creating the new combined corporation.

Step 4: Managing CRA Accounts and Business Numbers

After the legal merger, you must update the CRA. The new amalgamated corporation usually retains the Business Number (BN) of the “dominant” predecessor corporation, while the BNs of the other merging companies are closed. Your payroll, GST/HST, and corporate tax accounts must be carefully integrated to avoid penalties or missed filings.

Step 5: Filing the Final Pre-Amalgamation Tax Returns

A Section 87 amalgamation automatically triggers a “deemed year-end” for all the predecessor corporations immediately before the merger date. Your accounting firm must file final T2 corporate tax returns for all the old companies up to this date. The new amalgamated company then starts its first official tax year on the date of the amalgamation.

How Much Does it Cost in Canada?

Merging companies involves structural reorganizations that require professional legal and accounting budgets.

Expense TypeEstimated Cost (CAD)
Government Registry Fees$200 to $400 (Depending on jurisdiction)
Lawyer Fees (Short-Form)$2,000 to $4,000
Lawyer Fees (Long-Form & Continuance)$5,000 to $15,000+
Accounting and Tax Integration$4,000 to $10,000+

How Long Does the Process Take?

Legally, a short-form amalgamation can be drafted and filed within 2 to 4 weeks. A complex long-form amalgamation requiring shareholder negotiations and cross-border continuances may take 2 to 4 months. ⏱ However, the back-office accounting integration-moving payroll systems, transferring bank accounts, and filing the final pre-merger T2 tax returns-often takes an additional 3 to 6 months to fully complete.

Frequently Asked Questions (FAQ)

Do we have to re-hire our employees?

No. In a legal amalgamation, the new corporation automatically steps into the shoes of the old corporations. All employment contracts, seniority, and accrued vacation pay flow seamlessly into the new entity without triggering termination or constructive dismissal.

Can we carry forward old non-capital tax losses?

Yes, generally speaking. Section 87 allows the new amalgamated corporation to utilize the non-capital losses of the predecessor companies. However, strict “acquisition of control” rules may restrict these losses if the merger resulted in a major change in ownership.

Does a merger trigger land transfer tax?

Usually, no. Because an amalgamation operates by operation of law (the entities fuse together), there is technically no “transfer” of real estate from one party to another. Most Canadian provinces do not charge land transfer tax on standard amalgamations.

What happens to existing contracts and lawsuits?

The new amalgamated corporation inherits all the assets, but also all the liabilities. Every existing commercial contract, lease agreement, and pending lawsuit automatically becomes the responsibility of the newly formed corporation.

Do the predecessor companies get dissolved?

Technically, no. Unlike a wind-up where a company is killed off, an amalgamation is like a river where two streams merge. The predecessor companies do not “die”; they continue to exist inside the newly formed amalgamated corporation.
