When Tax Loss Planning Collides with Acquisition of Control Rules: Lessons from Madison Pacific Properties Inc. v. The King
Tax planning can look clean on paper. However, the Tax Court of Canada often looks deeper. That is exactly what happened in Madison Pacific Properties Inc. v. The King, 2023 TCC 180.
This case is important for business owners, landlords, and investors. It shows how old tax losses can become a problem when new owners step in and change the business.
At first glance, the structure looked careful. The investors used voting shares and non-voting shares in a way that appeared to avoid control. Yet the Court focused on the bigger picture. As a result, the tax plan did not survive.
What happened in this case?
The company originally operated as a mining business. Over time, it built up large tax losses. Those losses had value because they could reduce tax in future years.
Later, two real estate groups became involved. They wanted access to those losses. So, a series of transactions followed.
First, the mining assets were moved out of the company into another entity. In simple words, the old business was lifted out and placed elsewhere. This left behind a corporate shell that still had the historical tax losses.
Next, real estate assets were moved into that shell. The company then became a real estate business rather than a mining business.
That shift mattered a great deal.
Why did voting and non-voting shares matter?
Under the Income Tax Act, the concept of control is very important. In simple terms, control usually means having enough voting shares to elect the board of directors.
So, voting shares give decision-making power. Non-voting shares, by contrast, may give an ownership interest in profits and value, but they usually do not give the same power to choose the board.
In this case, the investors took a structure that gave them most of the economic value through non-voting shares, while keeping the voting shares below the level that would normally show legal control.
In other words, they had most of the value, but not enough votes on paper to say they controlled the company in the usual technical sense.
Why did CRA and the Court still have a problem?
The Court did not stop at the share certificates. Instead, the judge looked at the full story.
For example, the Court looked at:
-
how the transactions were planned
-
who worked together
-
who chose the directors
-
who managed the company
-
who got the economic benefit
-
how the business changed from mining to real estate
As the Court reviewed these facts, it found that the company had been fundamentally transformed. The old mining business was gone. A new real estate business had taken its place. In addition, new economic owners stood to benefit from the old tax losses.
Therefore, the Court concluded that the structure frustrated the purpose of the loss restriction rules.
Which tax rule was at the center of the case?
The main rule was subsection 111(4) of the Income Tax Act. This rule deals with net capital losses after an acquisition of control.
In simple terms, when control of a corporation changes, old net capital losses usually cannot be used in later years.
The Court also looked at the broader purpose of the law. Then, it applied the General Anti-Avoidance Rule (GAAR) in section 245.
That is important. Even when a structure appears to fit within the wording of the law, GAAR can still apply if the result defeats the purpose of the rule.
What is the practical lesson for business owners?
This case sends a clear message.
Tax planning is not only about technical steps. It is also about purpose, evidence, and commercial reality.
So, if a corporation with old losses changes hands, changes business, and starts benefiting new owners, CRA will likely look very closely.
Likewise, non-voting shares do not automatically solve the problem. They may help shape legal ownership. However, they do not erase the economic reality of a transaction.
As a result, business owners should be careful when planning:
-
mergers
-
acquisitions
-
reorganizations
-
share restructures
-
real estate roll-ins
-
transactions involving companies with old tax losses
Why this matters to landlords and business owners
Many business owners focus on the opportunity in front of them. That makes sense. Yet tax structure matters just as much as business opportunity.
For example, if you buy into a company with historical losses, you may assume those losses will help reduce future tax. However, the Income Tax Act places limits on that result. If the structure crosses the line, the expected tax benefit may disappear.
That is why planning should happen early. First, the facts need to be reviewed. Next, the business purpose needs to be clear. Then, the documents and share structure need to support that purpose.
