Before You Set Up a Holdco, Read This

I recently heard a construction lawyer say that half the holdcos in Canada shouldn't exist. I don't know if he's right on the exact number, but the sentiment is close enough. The holdco question is one of the most consistently mis-answered structural decisions in Canadian small business, and construction is where I watch it get botched most often. Either an owner sets one up because a friend told them to, or an owner puts it off for years while the real reasons to have one quietly stack up in the background.

I want to write plainly about this, because there's a lot of noise on the topic and construction owners are usually reading it through the wrong lens.

What a Holdco Actually Is, Briefly

A holding company — I'll shorten it to holdco from here — is a corporation that holds the shares of your operating company. Your opco does the construction work. It hires the labour, signs the contracts, gets the bond, carries the liability. The holdco owns opco. You own the holdco.

That's the structural picture. The reason it exists is that a holdco creates a legal separation between where the money is made and where the money is held. Everything else — the tax, the creditor protection, the succession planning — flows from that one separation.

The Reasons Not to Set One Up

Let me get the wrong reasons out of the way first, because they come up constantly.

"It'll save me tax." Almost never, at least not the year you set it up. Dividends flowing from a Canadian opco to a connected Canadian holdco are generally tax-free under the current rules, but that's a deferral mechanism, not a tax reduction. You still pay tax when the money eventually leaves the corporate structure and lands in your personal hands. A holdco doesn't create tax savings. It creates optionality about when you pay tax. Those are different things and getting them confused can cost you.

"My friend has one." Your friend runs a different business, has different retained earnings, is in a different marital situation, has different kids, and has a different exit plan. Not a reason.

"My accountant said I should." Sometimes true. Sometimes it's an accountant quietly charging you $4,000 to $6,000 in setup fees and another couple of thousand a year in extra filings without ever really explaining the why. Ask them. If the answer is fuzzy, get a second opinion before you commit.

The Reasons That Actually Justify It

Here's what I see driving real, well-timed holdco decisions in construction, in rough order of frequency.

Creditor protection. This is the biggest one for construction, and it's the reason most accountants underweight. Your opco is where the risk lives. Bonded jobs, jobsite liability, subcontractor disputes, holdback fights, warranty claims — all of it hits opco first. Retained earnings sitting inside opco are exposed to every one of those risks. Moving surplus cash up to a holdco each year, cleanly and inside the tax rules, protects those retained earnings from claims against the operating business.

The word doing the work in that paragraph is surplus. Your surety and your banker still want opco to hold enough working capital to look strong. Stripping opco too aggressively creates a different problem, and it's one your bonding agent will find before you do.

Getting surplus cash out of opco to invest. Once you're profitable enough to be retaining more than you can efficiently redeploy back into the business, that surplus starts creating a specific problem: passive investment income. Left in opco, retained earnings eventually throw off enough investment income to grind down your small business deduction — the $50,000 threshold above which your access to the low corporate tax rate on active income starts shrinking. Moving surplus up to a holdco keeps the investment income out of opco and preserves the SBD. This becomes urgent faster than most owners realize, especially for construction businesses that have been retaining well through a good decade.

Owning real estate separately from the operating business. Most construction owners eventually buy the yard, the shop, the equipment storage building. Holding that real estate inside opco is almost always a mistake, because the real estate stays exposed to operating risk and, when you eventually sell the business, it complicates the transaction. A holdco — or more often a sister real estate corporation — lets you own the property cleanly, rent it back to opco at fair market rates, and keep the two asset pools separate for whatever comes next.

Setting up for sale or succession. If you're within five years of selling the business or handing it to a partner or family member, a holdco is almost always part of the picture. It supports the Lifetime Capital Gains Exemption purification process, enables an estate freeze if you're bringing in the next generation, and gives you a clean vehicle for whatever proceeds land after the deal. I watch construction owners think about this in year four of a five-year runway. Year one would have been better.

Splitting income with family members who genuinely work in the business. Post-TOSI, this is a narrower door than it once was — a spouse or adult child has to be putting in real, provable hours — but the structure can support flexible dividend planning across shareholders where it's legitimate. Rarely the driver on its own. Usually a nice bonus on top of one of the reasons above.

When It's Premature

If you're the sole shareholder, three years or so into the business, your retained earnings are modest, your family isn't involved in the business, you don't own real estate through the corp, and you're at least a decade from thinking about selling — a holdco is probably premature. The setup costs, ongoing filing costs, and administrative complexity aren't earning their keep yet. Get the operating business stable and profitable first. The right time will announce itself.

The one exception, again, is creditor protection. If you're already at the point where opco is holding meaningful retained earnings and doing genuinely risky work, the calendar age of the business matters less than the size of the exposure.

What It Actually Costs

Being honest about the number, because I don't see this written down often enough.

Setup — corporate lawyer to incorporate the holdco, usually paired with a section 85 rollover to move shares of opco underneath it — runs $4,000 to $10,000 in professional fees depending on complexity. Ongoing costs are a second T2 return each year, minimum book compilation for the holdco, and modest additional administrative work. Realistically, add somewhere between $2,000 and $3,500 a year to your accounting fees for as long as the structure is in place.

That's a real number. It should earn its keep. The tests above are how you decide whether it's earning it.

Construction-Specific Things to Know Before You Commit

A few caveats worth knowing before you make the call.

Personal guarantees usually pierce right through a holdco. If you've personally guaranteed the bond, the line of credit, the equipment lease — the holdco doesn't protect the personal guarantee. It protects the retained earnings inside itself, which is different. Anyone selling you creditor protection as absolute isn't being straight with you.

Your surety watches inter-corporate dividends more closely than you might think. Aggressively moving cash out of opco each year can trigger questions about working capital adequacy at renewal. Manageable, but it needs to be coordinated with your bonding agent, not done in the dark.

Section 55 is real. There are anti-avoidance rules that govern how cash moves between related corporations, and any competent Canadian tax accountant knows them well. But I've seen a couple of situations where a holdco was used in ways that created a nasty surprise years later. Your accountant should be able to explain how section 55 applies to your specific plan without hesitation. If they can't, that's a signal.

And the timing matters. A holdco set up cleanly at the right moment costs a few thousand dollars and takes a few weeks. A holdco retroactively fitted onto a business you're trying to sell in six months is a much bigger project, and sometimes the window for the cleanest tax treatment has already closed.

The Question to Actually Ask

The holdco question shouldn't be should I have one. It should be what am I trying to solve, and is a holdco the right tool for it.

If the answer is "I'm building meaningful retained earnings and I want to protect them from operating risk" — yes, probably. If the answer is "I'm about to buy the yard and the building" — yes, at least look at it. If the answer is "I'm within five years of selling or transitioning" — yes, and stop waiting. If the answer is "my friend has one and it looks impressive on a business card" — no. If the answer is a shrug — no, not yet.

Most of the holdco mistakes I see aren't the wrong structure. They're the right structure at the wrong time. Either years too early, when it just adds cost, or years too late, when the window for the cleanest execution has already closed.
