The short answer
Decide what this person will do without a lawyer looking over their shoulder, then hire for that. In Ontario, a law clerk works under a lawyer's supervision, while a licensed paralegal can take certain matters on their own, so the title you post decides who applies. After that, write down how the lawyers you support actually work, and hire the law clerk whose working style fits, not just the one with the longest resume or the best interview. A poor fit tends to show up as drafts that come back for a second round, and by then the billable hours are already spent.
Why this hire is hard right now
The pool is small, and public employers draw heavily from it. Job Bank counts about 11,760 people in paralegals and related occupations, the group that includes law clerks, in the Toronto region. It rates the outlook "moderate" for 2025 to 2027: a few new positions, several openings from retirements. Provincial, local, and federal public administration employ 28%, 24%, and 19% of that group, and professional, scientific and technical services, the category law firms fall in, employs 26%. A Toronto firm is likely recruiting from the same people governments are.
Research and drafting are core law clerk work, and BLS says AI may reduce demand for paralegals and legal assistants in the US. Where candidates have choices, how your lawyers work is part of what you are offering. Know it, write it down, and hire someone whose style matches or complements it.
What a law clerk does
In Ontario, the Institute of Law Clerks of Ontario (ILCO) describes a law clerk as a legal paraprofessional who works under a lawyer's supervision, doing administrative duties or delegated substantive work. Law clerks do not provide services directly to the public. Licensed paralegals are a separate profession, regulated by the Law Society of Ontario since 2007, and can represent clients in matters such as Small Claims Court, provincial offences, and administrative tribunals.
Use the work to choose the title:
| If you need someone to | Hire a | Why |
|---|---|---|
| Draft documents, research, and manage files a lawyer reviews | Law clerk | Delegated work under a lawyer's supervision |
| Appear for clients in Small Claims Court or before a tribunal | Licensed paralegal, or a lawyer | Licensed paralegals can represent clients in these matters |
| Provide legal services to the public on their own | Licensed paralegal, or a lawyer | Law clerks do not provide services directly to the public |
One trap: in Canada, "law clerk" can also mean a judicial clerk who works with a judge, a job Mohawk College says requires a law degree. Say what you mean in the posting: supervised drafting, research, and file work at a law firm.
Working style: write it down first
Because a clerk's work always goes back to a lawyer, fit is mostly about hand-offs: what you explain, what you leave to them, and how you want the work returned. Answer each row for every lawyer the clerk will support, separately.
| Moment | Write down, for each lawyer | What a mismatch looks like |
|---|---|---|
| Something goes wrong | Do you want to hear the moment a deadline is at risk, or once there is a plan? | The clerk fixes a missed step quietly, and you hear about it from opposing counsel. |
| Instructions conflict | When your instruction doesn't match the file or the rules, should the clerk follow it, ask first, or flag it in writing? | A draft is built on the wrong instruction and surfaces at review. |
| Feedback | Do you want a first draft early and rough, or only when it is finished? Do you mark up every line? | The clerk polishes for days a draft you wanted rough, or hands in a rough draft you expected to file. |
| Speed against quality | Which documents can go out fast after a quick review, and which must be exact the first time? | Every draft gets the same effort, so urgent ones run late and careful ones are rushed. |
Delegation is the job. The clerk writes the first draft; the lawyer owns the last one.
Then show the page to your finalists and ask which rows they would find hardest. A candidate who names a row and says how they would handle it tells you more than one who says "I'm flexible."
What a bad hire costs
The most transparent estimate puts the cost of replacing an employee at about a fifth of salary, and it is probably low. A 2012 review by the Center for American Progress found a median of 21% of annual salary across most jobs, and 20% for jobs paying under US$50,000. Only 2 of its 11 papers counted indirect costs such as lost productivity. The data are historical and American, so read them as an order of magnitude. A firm also pays in lawyer time: review that goes unbilled, and business development time spent managing a working relationship.
The stakes are not only internal. LAWPRO, the professional liability insurer for Ontario lawyers, attributes about two-thirds of its claims to human error, including communication breakdowns and poor calendaring. Its articles are about lawyers' own errors, not staff, but they show where mistakes in the profession start: what gets said, and when.
What fit research does and doesn't show
Fit with a supervisor shows up mostly in how people feel. In a 2005 meta-analysis of 172 studies, it tracked satisfaction with the supervisor (corrected correlation .46) and the job (.44), and much less performance (.18) or tenure (.09), with 5 to 14 studies behind each figure. A mismatch is less likely to make a clerk bad at the work than to make the working relationship worse. That still matters:
A lawyer who dreads handing work over will hand over less.
How to screen for fit
Ask every candidate the same questions and score the answers against what you wrote down. A 2022 re-analysis of hiring research (Sackett and colleagues) ranked structured interviews first, with a validity of .42, ahead of work samples at .33, as summarized by SIOP. The figures cover job performance across occupations, not law clerks specifically.
Questions that surface working style
Ask about a real past situation, then keep asking "what did you do next?" until you hear actions, not intentions.
- Something went wrong: "Tell me about the last time you found an error in your own draft after a lawyer had it. What did you do first, and who did you tell?"
- Instructions conflicted: "A lawyer's instruction didn't match what the file or the rules required. What did you do?"
- Feedback: "Describe a draft that came back covered in changes. What did you do with the comments, and what changed in your next draft?"
- Speed against quality: "Tell me about a filing where there wasn't time to check everything. What did you check, and what did you leave for the lawyer?"
A 30-minute work sample
Hand over a one-page fact summary and ask for a short draft, such as a chronology or a cover letter. Build in two instructions that conflict and one missing fact, such as an undated notice. Watch whether the person asks, flags, or guesses, and whether they say what they assumed. A guess said out loud is better than a silent one.

Ask about real past situations: finding their own error, an instruction that didn't fit the file, feedback, and speed against accuracy. Use the same questions for every candidate and add a short work sample.
