Deal Structuring & M&A in Canada

Deal structuring is the backbone of every merger or acquisition. In Canada, where regulations and tax rules vary by province, the structure can decide whether a transaction runs smoothly or faces costly delays.

As M&A activity grows more complex, structuring has become just as important as valuation or price negotiation. This article explains how deal structuring works in Canada, outlines the main choices that shape a transaction, and shows how an M&A data room keeps everything organized from first draft to closing.

Understanding deal structuring in M&A

Deal structuring means organizing every part of a merger or acquisition so the transaction closes on the right terms. It combines the price, the payment form, shareholder value, the risk allocation, the tax and legal framework, and the timing needed to complete the deal. 

Here’s the general flow of merger and acquisition from start to finish:

• Letter of Intent (LOI). The buyer and seller outline the main points, such as price range and key terms.
• Due diligence. The buyer reviews the financial, legal, and operational information of the target company while the seller provides the data.
• Deal structuring. The parties decide whether it’s an asset or share purchase, how it’s financed, and what adjustments apply for net debt or working capital.
• Agreement drafting. Lawyers prepare formal documents such as the Share Purchase Agreement (SPA), Asset Purchase Agreement (APA), or plan of arrangement for more complex or public deals.
• Approvals and closing. Boards, regulators, and sometimes courts review the transaction before ownership and funds officially change hands.
• Closing. All documents are signed, funds are transferred, and the integration process begins.

Each stage connects to the next. If due diligence reveals new risks or tax issues, the structure is adjusted. When everything aligns, the parties move to board approval, regulatory filings, and finally, closing.

Core components of a deal structure

Let’s define who carries the risk, how payment works, and how the deal moves to closing.     

Asset purchase vs. share purchase  

Canadian deals usually take one of two forms: an asset sale or a share purchase transaction.

• In an asset sale, the buyer selects which assets and liabilities to take. This structure limits exposure to unforeseen liabilities, though it often requires more third-party consents and can trigger complex tax implications.
• In a share purchase transaction, the buyer acquires all issued and outstanding shares of the target corporation, assuming both its assets and obligations. This route offers continuity for employees, customers, and suppliers, but transfers every existing risk along with it.

Sellers generally prefer share transactions because they can qualify for capital gains treatment. Buyers, on the other hand, often push for asset deals to cherry-pick what they want and leave behind what they don’t. 

In the end, the decision usually depends on which side values simplicity over control.

Payment structure

Once the purchase type is clear, the next step of merger and acquisition is deciding how the buyer will pay. The payment mix affects timing, taxes, and investor confidence.

• Cash payments. Straightforward and quick but often require financing or bridge loans.
• Buyer shares. Help align long-term interests, but they bring added disclosure obligations under Canadian securities laws.
• Earn-out structure. Links part of the purchase price to the company’s future results – a useful tool when buyer and seller see value differently.
• Vendor notes. Allow deferred payments, easing cash strain for buyers while giving sellers partial security over time.

Pricing adjustments

Even after the main price is agreed upon, the details can shift before closing. Business performance, cash levels, or hidden debts discovered during due diligence can all influence the final amount. That’s why most Canadian deal structures include pricing adjustments such as:

• Working capital adjustment. Ensures the company has enough operating funds after the transfer to run normally.
• Net debt adjustment. Reconciles the difference between assumed debt and actual liabilities at closing.

These mechanisms protect both sides. Buyers avoid paying for short-term fluctuations, while sellers get credit for maintaining healthy operations. Yet, the right balance depends on how stable the target’s finances are and how much confidence both sides have in the company’s reporting. 

Risk protections 

Even after closing, risk doesn’t disappear, making buyers and sellers use different tools to control exposure.

One common way to handle this is through escrow accounts or holdbacks. Here, part of the purchase price is set aside for a short period after closing. If an issue comes up – for example, an unpaid tax bill or a missing contract – the funds can be used to cover it.

Beyond that, some buyers and sellers also use representation and warranty insurance (RWI). This policy covers certain promises made in the contract, such as the accuracy of financial statements or ownership of assets. If something turns out to be wrong, the insurer pays instead of the other party. 

Other tools, like indemnities or liability limits, define how long claims can be made and how much can be recovered. These terms keep the process predictable. 

Canadian regulatory and tax framework

Canada’s oversight system has multiple layers – federal reviews, provincial rules, and court approvals. Understanding these helps avoid delays and compliance risks.

Investment Canada Act review

For foreign buyers, the Investment Canada Act (ICA) determines when a transaction requires review or approval. As of 2025, direct acquisitions exceeding roughly CAD 1.38 billion in enterprise value generally trigger a review. Smaller transactions usually only need a short notification.

The review focuses on the deal’s “net benefit to Canada,” which includes factors such as job impact, innovation potential, and local economic growth. 

Competition Act reviews

Meanwhile, the Competition Act addresses a different concern – market concentration. Large mergers may require pre-merger notification, prompting the Competition Bureau to evaluate whether the transaction could reduce competition or create market dominance.

If issues arise, the Bureau may request data, extend timelines, or even require remedies such as divestitures. However, most Canadian M&A deals proceed without intervention, provided that the parties engage early and disclose their competitive rationale. This stage typically runs parallel to the ICA review, so coordinating both filings can prevent unnecessary duplication.

Plan of arrangement for public companies

Public mergers often use a plan of arrangement under the Canada Business Corporations Act. This is a court-approved process that allows flexible combinations of cash, shares, or internal restructuring.

Shareholders must approve the transaction by a two-thirds majority, and a final court order confirms it. This way, the system ensures equal treatment of all shareholders, including minority investors.

Securities and tax considerations

Canada’s treatment of capital gains, dividends, and interest affects how ownership and liabilities are structured. Many companies plan early, deciding which entity holds the target, how shares move, and how to minimize double taxation.  

Coordinating with tax and legal advisors ensures these details are addressed before signing.

From a tax planning perspective:

• Share deals often favor sellers. Gains on share sales are generally taxed as capital gains.
• Asset transactions can lead to double taxation. The company pays tax on asset sales, and shareholders may pay again when proceeds are distributed. 
• Cross-border transactions can trigger Canadian withholding tax. Deferred or contingent payments to non-residents often fall under these rules.

Corporate and provincial details

Beyond federal oversight, Canadian corporate law and employment law vary across provinces. These differences can directly influence deal structure, due diligence, and integration planning.

For instance, British Columbia applies its own standards for employee transfers and reasonable notice periods during workforce transitions. In contrast, Ontario or Alberta may interpret these obligations differently.

How structure connects valuation and governance

In deals involving foreign investment or private companies, structure is what keeps the process fair and transparent while holding boards accountable for their decisions. 

Here is how Canadian businesses act in the company’s best interests and demonstrate that every transaction offers fair value. 

Keeping the process fair

During take-over bids, boards often form independent committees to review offers and protect minority shareholders. These committees ensure that everyone holding the same class of equity securities is treated equally.

Defending against hostile bids

Sometimes, bids come without invitation. When a hostile bid appears, the target’s board can introduce shareholder rights plans or other defensive tactics to maintain control of the process.

After the vote: what changes legally 

Once a deal is approved, structure defines how companies merge on paper and in practice. When two amalgamating corporations unite, they become one amalgamated corporation, and the original entities cease to exist. Shareholders keep their legal title, while Canadian residents remain under standard tax and disclosure rules. 

Transparency across borders

A detailed disclosure document outlines the deal’s terms so that all outstanding voting shares are counted on the same facts. However, deals involving non-Canadian buyers in the Canadian market often require additional filings or extended review periods. 

A typical 6–10-week path from LOI to close

Many mid-market Canadian M&A transactions follow a similar timeline:

Week	Key activity	Lead team
1	Sign LOI and set preliminary terms.	Executives
2–3	Conduct due diligence of the target company and upload documents to the data room.	Buyer and advisors
3–4	Design structure, draft SPA/APA, and confirm tax approach.	Legal and finance
5	Finalize pricing and escrow details.	Deal leads
6	Submit filings under the Investment Canada Act and Competition Act.	Regulatory counsel
7	Secure board and shareholder approvals.	Corporate secretary
8–9	Complete financing and closing deliverables.	Executives
10	Transfer ownership and start integration.	Both sides

Data room software for Canadian M&A

Any of the recent M&A deals definitely involves hundreds of files and constant updates. It’s not a surprise that data rooms have become standard in Canadian deal execution because they provide secure control over sensitive information. They also centralize due diligence and help you maintain consistent records across every draft and upload.

A dedicated M&A dataroom lets you:

• Control who sees and downloads documents.
• Add watermarks and detailed audit trails.
• Manage questions and clarifications in one dashboard.
• Track activity for transparency and compliance.

If you’re managing complex diligence or cross-border reviews, consider adopting the data room software to keep everything under control and on record.
