A Toronto mid-sized firm decides it wants a real corporate practice. Not the one partner who happens to do corporate work between other files, but an actual group, with capacity, that clients think of first. There are three ways to make it happen: hire a lateral partner with a book, build the group from your own associates, or bring over a team of two or three lawyers together.
Most firms pick the first one, fast, without comparing the economics of the other two. Each route has a different cost, a different payback horizon, and a different risk profile: book portability on a lateral, attrition on an internal build, execution complexity on a team lift-out. The one that delivers billings this fiscal year is rarely the one that delivers the best value over three.
Route one: hiring a lateral partner
The lateral hire is the most common choice because it’s the fastest. Bring over a partner with an established book and you have billings inside the fiscal year, assuming the book actually moves.
The costs are larger than the recruitment fee: the guarantee or draw, the compensation adjustment across your existing partnership, and the integration cost in partner time.
The central risk is the book. A book that looks personal on paper often turns out to be institutional: the work followed the old firm, its brand, or a relationship partner who isn’t coming. When that happens you’ve paid a guarantee for billings that stayed behind. It can be your best hire of the decade or a six-figure guarantee with nothing to show for it, and the gap comes down to how portable the book really is.
Testing that is the part firms most often skip, and it’s a defined step on our lateral mandates: which clients move with the partner, which stay at the originating firm, and how the transition is communicated to those clients. Validating a book before you make an offer takes discipline, because if a meaningful share of the candidate’s top clients conflict out, you want to know before term sheet discussions rather than after. Lateral partner moves are typically retained for that reason. Our guide to hiring a lateral partner in Toronto covers how to test portability and structure the move.
Route two: building the group from your associates
Building from within is the route firms dismiss, and they shouldn’t. The payback is longer, but the cost is much lower and the lawyers are already aligned with how your firm works. You’re not betting on a book moving.
It requires three things. Real work to feed the associates, because you can’t grow a corporate group on scraps between other files. A partner willing to supervise properly rather than delegate and disappear. And a compensation structure that keeps a good sixth-year from leaving the moment they become useful. The Law Society of Ontario’s 2024 annual report counts 45,109 lawyers practising in Ontario, out of 60,590 licensees, so the constraint isn’t supply. It’s whether your firm will do the internal work.
Be honest about the timeline: in our experience it takes three to five years to reach a self-sustaining group, with attrition risk in the middle years, when a well-trained fifth-year is most attractive to other firms.
There’s no search mandate in any of that, and we’ll say so. What we can give you is the number that decides it. Our 2026 salary guide is published in full and ungated, covering associate through partner on a Toronto baseline with adjustments for our other markets, so you can see what the market will pay your fifth-year before someone else offers it. Retention on an internal build is a compensation question long before it’s a recruitment question.
Route three: acquiring a team
Acquiring a team is the least-discussed route and often the most efficient. Two or three lawyers move together and bring a functioning practice: the partner, the associates who do the work, and the relationships that hold it together.
The economics are frequently better than a single lateral at equivalent billings. A team arrives with its own capacity, so you’re not immediately hiring underneath the new partner, and it hedges the portability problem, because if the book doesn’t fully transfer the people who run the files are already there. It’s harder to execute, though: more people to align on compensation and title, more conflicts to clear, and more chance of a leak before anyone signs.
Our legal team includes former practising lawyers, so we can tell whether a group actually works as a unit, shared clients, shared files, genuine working relationships, or whether they just happen to sit near each other. That distinction decides whether the group stays together after the move.
On a team approach, the same person needs to run all the conversations on the same timeline. If one lawyer hears something different from another, the deal falls apart. Our senior partners handle each engagement personally for that reason.
Group moves are typically retained and take six to nine months on a multi-partner lift-out.
The conflicts check that kills deals late
On the searches we run, conflicts are the most common reason a lateral or team move falls apart in the final stage. A firm spends months courting a partner, agrees on economics, drafts the announcement, and then the formal check surfaces a client relationship that can’t coexist with an existing file.
The fix is sequencing. The formal check is yours to run, but it should land before compensation negotiation rather than after, and the groundwork starts earlier still.
That is why our lateral process begins with mapping: before any candidate is approached we map the comparable firms by practice area, partner-level seniority and conflicts profile. It doesn’t replace your formal check, and it won’t catch everything, but it surfaces the obvious blockers while walking away still costs nothing. Ask any recruiter where conflicts sit in their sequence. Most firms forget to.
What the compensation structure has to absorb
A lateral at a guarantee changes the math for the partners already in the room. If a new partner is guaranteed a number that outpaces what existing partners draw on comparable billings, resentment follows, and it’s harder to unwind afterward than to plan for up front.
It helps to know what you’re competing against, because a partner weighing your firm may also be weighing a move in-house. In the Toronto market, a mid-market general counsel runs $280K to $380K in base salary and senior counsel at five to eight years of call runs $175K to $235K, per our published in-house counsel salary bands. We see both sides of that decision, which is the practical advantage of a legal desk covering firms and in-house teams at once: when a partner tells us they’re considering a move in-house, we know what that offer looks like and what it would take to keep them. If that’s the move you’re weighing, our guide on how to hire your first general counsel in Canada covers it.
Where a recruiter helps, and where they don’t
A recruiter is central to a lateral or team move and largely irrelevant to an internal build. We’d rather say that up front than take a mandate we can’t add value to.
For a lateral or a team, the value is discretion, market mapping, and a neutral party who can approach a partner without a competing managing partner making the call directly. Our searches are run personally by senior partners, and our legal team includes former practising lawyers, so the first conversation is substantive: practice fit, deal exposure, firm culture. Partners take that call. They don’t take the other one.
For an internal build, supervision, work allocation and compensation design are not things a recruiter touches. Use the salary guide, keep the fee.
If you’re going the lateral or team route, three questions separate a specialist from a generalist, and our answers sit next to them.
- How many partner-level moves have you completed in this practice area, in Toronto? Corporate is not litigation. Ask us and we’ll give you a straight read on where we work and where we don’t.
- Who actually runs the search? Our senior partners run each engagement personally, and junior staff don’t own client relationships. Ask anyone else the same question.
- What happens if the conflicts check fails? The honest answer is early mapping and a clean plan for walking away, not a promise it never happens.
We run legal search across Toronto, Hamilton and the Greater Golden Horseshoe, Kitchener-Waterloo, Ottawa and Vancouver. See how we work with firms on our law firm recruitment page, or start a conversation. We work on contingent search by default, with no fee until a candidate is placed, and move to retained for lateral partner and group moves where the diligence is the work. We’ll tell you which route fits, including when the answer is to build internally and skip the recruiter entirely.
FAQs
How should a law firm choose between hiring a lateral, building internally, or acquiring a team?
Match the route to your horizon. A lateral delivers billings inside the fiscal year and carries the highest variance, because everything depends on whether the book is personal or institutional. An internal build costs least but takes three to five years. A team move often has the best risk-adjusted economics at equivalent billings, because you acquire capacity rather than one person’s relationships.
Why do lateral partner deals fall apart at the last minute?
On the searches we run, most often a conflicts check that surfaces a blocking client relationship late, which is why the check should land before serious compensation talks. Our lateral process starts by mapping comparable firms on conflicts profile, before any candidate is approached. The next most common cause is a book that turns out to be institutional rather than personal, discovered only once the partner has moved.
Is acquiring a team better than hiring a single partner?
Often, yes. Two or three lawyers bring a functioning practice with its own capacity, which hedges the portability risk that makes single laterals so variable. It’s harder to execute: more people to align, more conflicts to clear, more chance of a leak, and six to nine months is a realistic timeline for a multi-partner lift-out. Group moves are typically retained for that reason.
Should a lateral or team move be run retained or contingent?
Retained, for both. We work on contingent search by default with no fee until a candidate is placed, and lateral partner and group moves are the deliberate exception. On these the work is the diligence: testing whether a book is portable, screening conflicts early, coordinating simultaneous approaches without a leak. All of that happens before anyone signs anything.
When is a recruiter worth the fee on practice group growth?
On lateral and team moves, where the value is discretion, market mapping and a credible first approach a competing firm’s managing partner can’t make directly. Our senior partners run each engagement personally, our legal team includes former practising lawyers, and because we recruit across both sides of the market we can usually give you a view on where a partner’s work originates and what would keep them. On a purely internal build there’s no search mandate and we’ll tell you so; use our ungated salary guide to benchmark retention and keep the fee.
