Ontario or Federal: Three Engineers Split on How to Incorporate

The situation

Huong, Samir and Rania had been operating their structural and civil engineering consulting practice out of Ottawa for about four years, splitting fees informally among themselves as the work grew from a handful of residential projects to municipal infrastructure contracts and private developer work across the region. Revenue had climbed past roughly $6 million a year, with two more engineers and a small support staff on the payroll, and the three founders had finally agreed it was time to stop operating as an informal arrangement and incorporate properly. What they had not agreed on was how.

All three were professional engineers licensed in Ontario, and the bulk of their work was still Ottawa and eastern Ontario projects — bridges, retaining walls, site servicing for subdivisions. But the practice had also picked up two contracts in the past year for clients in Quebec and Nova Scotia, and Huong, who handled most of the business development, believed that trend would continue. She wanted to incorporate federally. Samir, who ran the day-to-day project delivery side, thought that was overengineering a business that was still overwhelmingly local, and pushed for incorporating in Ontario, where they already held their professional licences and did nearly all their work. Rania, the third founder, agreed with Samir on cost and simplicity but did not want to lock in a structure that made it harder to expand later if the out-of-province work kept growing.

The problem

Incorporating a business in Canada means choosing between two separate legal regimes, and the choice is not just a formality. Incorporating under the Business Corporations Act (Ontario) creates a company whose existence is rooted in Ontario law; it can operate anywhere, but if it wants to carry on business in another province, it generally needs to register extra-provincially in each one, a modest but recurring filing and fee obligation. Incorporating under the Canada Business Corporations Act, the federal statute, creates a company with the right to carry on business and use its name across the country, but it still has to register in each province it actually operates in, so the federal option does not eliminate extra-provincial registration either — it mainly strengthens name protection nationally and can carry a small edge in perceived credibility with out-of-province clients and lenders.

The founders were talking past each other because they were weighing different things. Huong was thinking about name protection: a federal incorporation gives a business a stronger claim to its corporate name across Canada, which mattered to her because a competitor could otherwise incorporate an identically or confusingly named company in another province while their firm was still small enough that a name dispute would be a real distraction. Samir was thinking about ongoing cost and paperwork: federal corporations file both a federal annual return and, in most cases, provincial extra-provincial registrations and returns wherever they operate, which is more administrative overhead for a business that, on the numbers, was still almost entirely Ontario-based. Rania was thinking about optionality: whichever way they went, she wanted the shareholder agreement to make it straightforward to adjust the structure later without reopening a fight among the three of them.

There was a second layer specific to their profession. Ontario restricts who can offer professional engineering services to the public through a company: the business needs a certificate of authorization from the professional engineering regulator in Ontario, held by a licensed professional engineer who takes responsibility for the firm's engineering work, regardless of whether the company is incorporated provincially or federally. That requirement did not resolve the Ontario-versus-federal question, but it meant that either way, the corporate structure needed a shareholder or officer clearly designated to hold that responsibility, and the founders had not sorted out who that would be or what it meant for control of the company.

What we did

1. Mapped where the business actually operated and where it was likely to grow. A review of the past three years of billings showed that roughly 90 percent of revenue came from Ontario projects, with the Quebec and Nova Scotia work still a small but real fraction. That data mattered more than any of the founders' instincts, because it showed the out-of-province work was a genuine trend worth planning for, but not yet large enough to justify treating the business as a national operation from day one.
2. Explained the real difference extra-provincial registration makes, and what it does not. Both an Ontario-incorporated company and a federally incorporated one would need to register in Quebec and Nova Scotia to carry on business there lawfully, at broadly comparable ongoing cost. What differed was name protection: a federal incorporation would reserve the firm's name for use across the country immediately, while an Ontario incorporation would only protect the name in Ontario unless the firm separately registered it, or a similar name, in other provinces as it expanded. This was the point that most directly separated Huong's priority from Samir's.
3. Addressed the professional engineering ownership requirement directly. The certificate of authorization needed a designated professional engineer to take responsibility for the firm's engineering practice. We confirmed all three founders' licences were in good standing and built the officer designations into the incorporation documents so the certificate of authorization application would not stall on that requirement.
4. Proposed a structure that answered both founders' real concerns. The company would incorporate under the Business Corporations Act (Ontario), reflecting where the business genuinely operated and licensed its founders, keeping ongoing costs and filings closer to what Samir wanted. To address Huong's concern about the name, the firm would separately register its business name, and pursue a trademark application for its name and logo, giving it protection that did not depend on which incorporation statute was used and would hold up even if a similarly named company incorporated elsewhere.
5. Drafted a shareholder agreement with a built-in review trigger. Rather than leaving the Ontario-versus-federal question as something the three might revisit only if a crisis forced it, the agreement included a term requiring the shareholders to formally reassess the incorporation structure once out-of-province revenue crossed a set share of total billings, giving Rania the flexibility she wanted without requiring anyone to guess when the moment had arrived. The agreement also set out share classes, decision-making thresholds for major changes like converting to a federal corporation, and buyout terms if a founder wanted to exit.
6. Registered the company extra-provincially in Quebec and Nova Scotia at incorporation. Rather than waiting for a dispute over unregistered out-of-province activity, the firm registered in both provinces where it already had active contracts, so the two existing clients were served by a company properly authorized to carry on business there from the outset.

The outcome

None of the three founders got the structure they had originally proposed. Huong gave up on immediate federal incorporation, which she had genuinely preferred; Samir accepted the cost of a trademark application and extra-provincial registrations he had hoped to avoid for now; Rania got the built-in review mechanism she wanted but had to accept that it would only trigger conversion, not guarantee it, if the numbers did not move as she expected. It was a compromise all three could live with rather than a clean win for any one of them, reached after roughly three weeks of back-and-forth once the underlying facts were on the table.

The company incorporated under the Business Corporations Act (Ontario), obtained its certificate of authorization from the provincial engineering regulator with Samir designated as the responsible professional engineer, and filed its trademark application for its firm name shortly after. Extra-provincial registrations in Quebec and Nova Scotia were completed within the same month, at a modest combined cost that all three founders had budgeted for going in. The shareholder agreement's review trigger was set at a threshold the founders judged genuinely meaningful rather than symbolic, tied to the share of revenue coming from outside Ontario over a rolling period.

Roughly a year later, the out-of-province share of revenue had grown but had not yet reached the agreed threshold, and the firm continued operating under its Ontario incorporation without incident. Whether it converts to a federal corporation later remains an open question the founders can revisit on the terms they already agreed to, rather than one that requires reopening the argument from scratch.
