The Complete Hiring Guide for Canadian Small Businesses

Before you post: getting ready to hire

Define the role precisely before you write a job posting. A list of tasks is not a job definition. What does success look like at 90 days? What decisions will this person make independently versus escalate? What's the scope of the role in six months versus right now? Hiring without clear answers to these questions leads to either hiring someone under-qualified for what you actually need, or over-qualified for what you can actually offer them.

Set a budget that includes all-in employer costs, not just the salary. In Canada, employer costs on top of gross salary include: CPP contributions (matching the employee's contribution), EI premiums (employer pays 1.4x the employee premium), and WSIB premiums (rates vary by industry). For a full-time employee earning $45,000 annually in Ontario, total employer cost is typically $48,000–$51,000 when statutory costs are included. Benefits, if you offer them, add further. Budget for the actual cost, not the salary line alone.

Get your legal foundations in place before your first hire. You need a CRA payroll account (RP number), register at Canada.ca/business. Register with WSIB (Workplace Safety and Insurance Board) if you're in Ontario and your industry requires it. If your province requires it, register your payroll with the provincial authority as well. Post the Employment Standards poster (mandatory in Ontario under the ESA) in your workplace. Have your employment contract template ready. None of this takes long, but it all needs to happen before Day 1, not after.

Writing a job posting that attracts the right candidates

Use a clear, searchable job title. 'Customer Experience Ninja' will not appear in searches for 'Customer Service Representative.' Use the title candidates are searching for, not the title that reflects your company culture. Your culture description can go in the body of the posting.

Include specific responsibilities rather than vague category descriptions. 'Manage social media' is too vague. 'Create three to five posts per week across Instagram and LinkedIn, respond to comments and messages within 24 hours, and produce a monthly analytics report' gives candidates a real picture of the work. Vague postings attract applicants who project whatever they want onto the role, resulting in mismatched expectations after hiring.

Include a salary range. In Ontario, employers with 25 or more employees are legally required to include a compensation range in job postings under the Working for Workers Act (2023). For smaller employers, it's best practice regardless: it saves you time in screening, prevents salary negotiation surprises, and signals transparency that candidates, particularly stronger candidates with options, appreciate.

End the posting with an honest description of next steps. 'Applications will be reviewed starting [date]. Selected candidates will be contacted for a 15-minute phone call.' Candidates who understand the process are less likely to follow up excessively. For job posting writing guidance, see our detailed guide to writing a job posting as a small business.

Screening and interviewing efficiently

Define your must-have and nice-to-have criteria before the first application arrives, not after, when you'll be tempted to shift the criteria based on who applied. Must-haves are non-negotiable: things the person cannot learn quickly on the job or where a gap would be immediately disqualifying (a licence, a language, a specific system they need to use from day one). Nice-to-haves are advantages that would make the hire better but aren't deal-breakers.

Phone screen candidates on your shortlist before investing interview time. A 15–20 minute call that confirms the basics, their availability, their salary expectations, a brief account of their most relevant experience, will filter out mismatches before you put an hour of your time (and theirs) into an in-person or video interview. You'll also get a read on their communication style and professionalism before they've had time to prepare an interview persona.

Use a structured interview with the same five to seven questions for every candidate. Structure serves two purposes: it makes your comparison fairer (you're evaluating candidates on the same questions, not different conversations), and it reduces the influence of first impressions and affinity bias. Write a simple scoring rubric before the interviews and complete it immediately after each one not at the end of the day when your memory of earlier candidates has faded. For a list of effective interview questions, see our guide on interview questions to ask candidates in Canada.

The offer and onboarding

Always issue a written offer letter, even for small businesses where it might feel overly formal. The offer letter defines the employment relationship: role, compensation, start date, and any conditions of employment. More importantly for employers, it limits your ESA exposure on termination, courts have upheld much higher wrongful dismissal awards against employers whose written contracts did not explicitly address termination provisions. Have your offer letter reviewed by an employment lawyer for your first hire; the cost is minimal relative to the protection it provides.

Send a first-week schedule before Day 1. The new hire should arrive knowing what their first week looks like, what they'll be learning, who they'll be meeting, what they're expected to produce by the end of the week. First-day anxiety is real and is easily reduced by a clear, detailed agenda sent in advance. Assign a buddy an existing employee they can ask informal questions of, and introduce them by email or message before the start date.

Build a 90-day onboarding plan. It doesn't need to be elaborate, a simple week-by-week outline of what the new hire will learn, who they'll shadow, and what their first solo responsibilities will be. A 90-day plan signals that you've thought about their development and that there's structure to the role. It also gives you a framework for the 30, 60, and 90-day check-ins that determine whether the hire is working out. See our complete new employee onboarding checklist for Canadian employers.

Common small business hiring mistakes and how to avoid them

Hiring because you're desperate is the most common and most expensive mistake. When you're short-staffed and overwhelmed, the pressure to fill the seat overrides the judgment that would have screened out a poor fit. The hire is made, the fit is wrong, and within four months you're managing a performance issue, planning a termination, and re-hiring, at twice the cost of waiting for the right person. The fix is to start hiring before you're desperate: maintain a short list of candidates or keep a passive posting even when you're not actively searching.

Skipping the written employment contract is a legal risk that small business owners consistently underestimate. Under the ESA, employees dismissed without cause are entitled to statutory notice or pay in lieu. Without a written contract limiting this to statutory minimums, courts routinely award common law reasonable notice often one month per year of service at higher levels. For a three-year employee earning $60,000, the difference between a statutory minimum and a common law award can be $15,000 to $20,000. See our guide on employment contract basics for Canadian employers.

Other common mistakes: hiring someone too junior for the actual need (you want to save money on salary, but the role requires more experience than the hire has, and the gap costs you more in manager time than the salary savings); ignoring reference checks (references are not a formality, a two-minute call with a previous manager will often surface issues a structured interview won't); and starting without an onboarding plan, which leads to early turnover at the point when the new hire decides the role isn't what they expected and you haven't yet demonstrated that you're invested in their success.
