Architecture and engineering firms in Ontario face a set of HR challenges that most generalist HR guides overlook: licensed P.Eng employees are exempt from some ESA provisions (hours of work and overtime) but most of your staff are not; the non-compete ban affects technical knowledge retention strategies; the 2026 Pay Transparency Act applies to most A&E firms; and a structural talent shortage makes retention a survival issue. This guide breaks down the Ontario-specific compliance landscape and practical HR strategies for firms of all sizes.
What Makes Architecture and Engineering HR Different
Architecture and engineering firms look like white-collar professional services on the surface, but their HR environment is more complex than most. Licensing bodies, variable project pipelines, dual-track workforces (licensed and unlicensed), billable-hour economics, and a long-standing talent shortage create HR challenges that generic policies do not address.
| HR Challenge | Why It’s Different from Other Sectors | Ontario Implication |
|---|---|---|
| Dual workforce (licensed vs. unlicensed) | Licensed P.Eng or registered architect staff are regulated by provincial bodies with their own codes of conduct; unlicensed staff (EITs, technicians, admins) have full ESA coverage regardless | Separate employment terms, exempt vs. non-exempt overtime calculations |
| Project-based work cycles | Staffing needs fluctuate dramatically with project wins and losses; temporary layoffs and contract staff are common | ESA temporary layoff rules (13 weeks without pay / 35 weeks with benefits) apply; fixed-term contract renewal risk |
| Professional licensing requirements | P.Eng licensure requires PEO (Professional Engineers Ontario) membership; architects require OAA registration; ongoing CPD requirements | Employers must track CPD compliance for stamp-holding staff; credential lapse creates liability |
| Billable-hour culture | Utilization rates drive profitability; pressure to bill hours can create overwork and burnout | Overtime obligations exist for unlicensed staff regardless of utilization targets; psychological safety issues from hours pressure |
| Talent shortage | Engineering Canada projects a significant shortage of licensed engineers through 2030; architecture has similar pipeline issues | Retention is existential; compensation benchmarking and engagement strategies are not optional |
| Knowledge concentration risk | Technical knowledge (proprietary designs, client relationships, software configurations) is concentrated in key staff | Non-compete bans under Working for Workers Act 2021 require alternative IP protection strategies |
| 2026 Pay Transparency Act | Salary range disclosure requirements apply to most A&E firms; compensation structures that have historically been opaque must change | Non-compliance penalties doubled to $100,000 per violation under ESA amendments |
Professional Regulatory Framework in Ontario
Two key regulatory bodies govern the professional workforce at Ontario architecture and engineering firms:
Professional Engineers Ontario (PEO)
PEO is the licensing body for professional engineers in Ontario under the Professional Engineers Act. Only PEO-licensed individuals may use the P.Eng designation, approve engineering work products, or stamp drawings. Key HR implications:
- Credential verification: Employers have a duty to verify that any employee using a P.Eng designation is currently licensed. Stamp approval by an unlicensed person creates significant professional and legal liability.
- Continuing professional development (CPD): PEO members are required to maintain competence. While PEO does not mandate a fixed number of CPD hours (unlike CPA Ontario), employers should track professional development to support licence maintenance.
- Engineers-in-Training (EITs): EITs are working toward their P.Eng. They are not licensed professional engineers and do not qualify for ESA overtime exemptions. Many firms treat them the same as licensed staff—this is a compliance gap.
- Code of Ethics: PEO’s Code of Ethics governs professional conduct. HR policies on conflicts of interest, confidentiality, and quality assurance must align with PEO’s standards.
Ontario Association of Architects (OAA)
Architects in Ontario are regulated by the OAA under the Architects Act. Only OAA-registered architects may use the Architect title and take responsibility for architectural work products. The OAA also has experience requirements for registration and mandatory continuing education obligations that employers must support.
ESA Exemptions for Licensed P.Eng and Registered Architects
This is the area where most Ontario A&E firms get their employment standards compliance wrong. Ontario Regulation 285/01 under the ESA exempts licensed Professional Engineers and registered architects from certain ESA provisions—but the exemptions are narrower than most firms assume.
| ESA Provision | Licensed P.Eng / Registered Architect | Engineer-in-Training (EIT) | Technician / Technologist (CET) | Admin / Non-Technical Staff |
|---|---|---|---|---|
| Maximum daily/weekly hours of work (s.17) | EXEMPT | Full ESA coverage | Full ESA coverage | Full ESA coverage |
| Overtime pay at 1.5x after 44 hours (s.22) | EXEMPT | Full ESA coverage | Full ESA coverage | Full ESA coverage |
| Minimum wage | Full ESA coverage | Full ESA coverage | Full ESA coverage | Full ESA coverage |
| Vacation pay (s.33) | Full ESA coverage | Full ESA coverage | Full ESA coverage | Full ESA coverage |
| All 19+ ESA leaves | Full ESA coverage | Full ESA coverage | Full ESA coverage | Full ESA coverage |
| Termination notice and severance pay | Full ESA coverage | Full ESA coverage | Full ESA coverage | Full ESA coverage |
| Public holidays | Full ESA coverage | Full ESA coverage | Full ESA coverage | Full ESA coverage |
| Pay statements, pay equity obligations | Full ESA coverage | Full ESA coverage | Full ESA coverage | Full ESA coverage |
The critical point: The exemption applies only to licensed P.Eng and registered architects—and only covers maximum hours of work and overtime pay. Every other ESA standard applies in full to all employees, including licensed professionals.
The exemption reflects a policy assumption that professional engineers have the expertise and bargaining power to negotiate their own employment terms—and are often compensated with salaries that implicitly account for long hours. In practice, this means a licensed P.Eng on salary who works 55 hours per week has no ESA overtime claim. But an EIT doing the same work does.
Practical implication: If your employment contracts, timekeeping systems, or overtime policies treat all technical staff the same regardless of licensure status, you likely have an ESA compliance gap. Run an audit before an employment standards officer does it for you. Related: Independent Contractor vs Employee Ontario.
Non-Compete, Non-Solicitation, and IP Protection
Architecture and engineering firms depend heavily on proprietary knowledge—client relationships, design methodologies, software configurations, and institutional project knowledge. When a senior engineer or architect leaves, they often take that knowledge with them. The Working for Workers Act, 2021 significantly changed what firms can do about this.
Non-Compete Agreements: Void for Most Employees
Since October 25, 2021, Ontario employers cannot include non-compete clauses in employment agreements with employees. Any such clause is void and unenforceable under section 67.2 of the ESA. The only exceptions are:
- Sale of a business: An individual who sells their firm and becomes an employee of the purchaser may agree to a non-compete as part of the sale transaction.
- C-suite executives: Employees in an “executive” role (CEO, COO, CFO, CTO, and true equivalents) may still be subject to non-compete clauses.
A senior architect or principal engineer who does not hold an executive title cannot be bound by a non-compete—even if they have extensive client relationships and proprietary knowledge.
What Still Works
| Protection | Validity in Ontario | Notes |
|---|---|---|
| Non-disclosure / Confidentiality agreement | Valid and enforceable | Should specifically cover project files, client data, designs, software configurations, and pricing methodologies. Survives termination. |
| IP assignment clause | Valid and enforceable | Ensure employment contracts assign all work product to the firm (not just what was done “on company time”). Critical for stamp-approved design work. |
| Narrow non-solicitation (clients) | Generally valid if narrowly scoped | Must be reasonable in scope (specific client list vs. “all clients”), geography, and duration (1–2 years max). Courts scrutinize broadly worded provisions. |
| Narrow non-solicitation (staff) | Generally valid if narrowly scoped | Protects against a departing employee recruiting your team; must be reasonable in scope and duration. |
| Notice period / garden leave | Valid and enforceable | Use proper notice periods (common law, not just ESA minimums) to allow time for client transition and knowledge transfer. |
Pay Transparency Act 2026
Ontario’s Pay Transparency Act, as amended by the Working for Workers Four Act (2024), introduces salary disclosure requirements that took effect January 1, 2026. These apply to most architecture and engineering firms with 25 or more employees in Ontario.
| Requirement | Details | Non-Compliance Risk |
|---|---|---|
| Salary range disclosure in job postings | All publicly posted positions must include the expected compensation range. The range cannot exceed $50,000 (e.g., posting “$80,000–$130,000” is acceptable; “$60,000–$140,000” is not) | $100,000 per violation under ESA |
| No requirement for Canadian work experience | Job postings cannot require Canadian work experience as a condition. Relevant technical experience is acceptable; where it was obtained is not. | Complaint-based; HRTO exposure for discrimination on protected grounds |
| AI use disclosure | If AI is used to screen applications or assess candidates, this must be disclosed in the job posting (Working for Workers Four Act, s.5.4) | Administrative penalty up to $100,000 |
| Vacancy status confirmation | Employers with 25+ employees must confirm the position is a genuine vacancy. Cannot post speculatively to build a candidate pool. | ESA administrative penalties |
| Annual reporting (100+ employees) | Employers with 100+ employees must file pay transparency reports with the Ontario government by January 15 each year | Filing failure exposed under public register |
Pay transparency also forces a review of compensation equity. If your firm has never conducted a formal compensation benchmarking exercise, now is the time. A fractional HR consultant can run a market analysis and help design salary bands that comply with the $50,000 cap requirement. See: Compensation Benchmarking Ontario.
Compensation Structures for Technical Professionals
A&E firms typically compensate licensed professionals on salary, with variable incentives tied to project performance or firm profitability. Here is a framework for how compensation typically works—and where common HR problems arise:
| Compensation Element | Common Structure | Key HR Consideration |
|---|---|---|
| Base salary | Market-benchmarked annual salary; typically reviewed annually | Must disclose range in job postings (25+ employees); P.Eng and architect salaries often require premium over EIT rates |
| Project-performance bonus | Percentage of project profitability or on-time delivery; paid at project close or year-end | Bonus criteria must be documented; if bonus is “expected,” courts may treat it as an implied term of employment affecting common law damages |
| Professional development allowance | Employer-funded CPD, conference attendance, software training | If linked to a repayment clause (employee leaves within X years), the clause must be reasonable and disclosed at hire |
| Overtime / extra hours (for EITs and non-exempt staff) | EIT and technical staff who work above 44 hours/week are entitled to 1.5x their hourly rate or equivalent time off in lieu | If your firm does not track hours for EITs, you are exposed to ESA back-pay claims; track carefully |
| Profit-sharing / partnership track | Senior staff may participate in firm profitability or transition to partnership equity | Partnership arrangements must be separate from employment. Equity partners are not employees; clarity on the transition point is essential to avoid misclassification |
Talent Shortage and Retention
The engineering talent shortage in Canada is structural, not cyclical. Engineering Canada’s data shows that 1 in 8 job openings in engineering fields is unfilled. Architecture faces similar constraints as schools of architecture have not scaled program capacity to match industry growth and retirements.
For Ontario A&E firms, this translates directly to a retention imperative. Replacing a licensed architect or senior P.Eng costs an estimated 100–200% of annual salary once you account for recruitment, onboarding, and the 12–18 months before a new technical hire reaches full productivity.
The following retention levers consistently drive results in A&E environments:
| Retention Lever | What It Looks Like | Common Mistake |
|---|---|---|
| Career path transparency | Written criteria for progression from EIT to P.Eng to Senior Engineer to Principal. Employees should know what milestones trigger each stage. | Vague “we’ll know it when we see it” promotion criteria—leads to perceived favouritism and attrition of high performers |
| PEO/OAA exam and licensure support | Study leave, exam fee coverage, mentorship from licenced staff | Expecting EITs to pursue P.Eng on personal time; losing them to firms that actively support licensure |
| Project assignment strategy | Rotate staff through project types to develop skills; avoid parking high-potential staff on low-complexity work | Assigning engineers based solely on immediate need; over-utilizing top performers |
| Psychological safety and manager quality | Technical professionals cite poor management as the primary reason for leaving, not compensation | Promoting best technical performers into management roles without leadership development |
| Flexible scheduling | Project-phase flexibility; compressed workweeks during low-intensity phases | Inflexible in-office requirements post-pandemic, especially for roles where remote work is feasible |
| Compensation benchmarking | Annual review against Engineering Change and other Canadian engineering salary surveys | Setting compensation in year one and not reviewing for 3–4 years; losing to larger firms or US employers |
OHSA and Site Safety Obligations
OHSA applies to all A&E workplaces in Ontario. For firms with office-only operations, the focus is primarily on workplace violence and harassment policies and ergonomics. For firms with field operations (site visits, inspections, construction oversight), more intensive OHSA obligations apply—often overlapping with the Constructor obligations under O.Reg. 213/91 for construction projects.
| OHSA Requirement | Threshold | A&E Firm Context |
|---|---|---|
| Written workplace violence & harassment policy | 5+ workers | Must cover digital communications and off-site events (Bill 190, 2024). Annual review required. |
| Health and Safety Representative | 6–19 workers | Must be a non-management worker, selected by workers |
| Joint Health and Safety Committee (JHSC) | 20+ workers | At least 2 certified members; monthly meetings; annual workplace inspection |
| Site-specific H&S obligations | Field/inspection roles | Engineers doing site visits must comply with O.Reg. 213/91; hard hats, fall arrest, safety footwear requirements apply at active construction sites regardless of whether your firm is the constructor |
| AED on premises | 20+ workers (construction sites from June 2026) | Applies primarily to construction sites, not office environments, but employers with 20+ staff at a fixed location should assess |
HR Support Models for Architecture and Engineering Firms
Most Ontario A&E firms fall between 10 and 150 employees. Very few have a dedicated in-house HR function, yet the compliance landscape—ESA exemption nuances, PEO licensing obligations, Pay Transparency Act, OHSA—is complex enough to generate serious liability without proper HR infrastructure.
| Firm Size | Typical HR Gap | Recommended Model | Approximate Cost |
|---|---|---|---|
| Under 15 employees | No employment contracts; no handbook; no overtime tracking for EITs | One-time HR consultant engagement for contracts and handbook + annual compliance review | $2,000–$8,000 one-time |
| 15–40 employees | Inconsistent performance management; P.Eng vs. EIT ESA confusion; no formal compensation structure | Fractional HR retainer (8–15 hours/month); covers compliance, ER, compensation design | $1,800–$3,500/month |
| 40–100 employees | First harassment complaints; talent shortage driving retention issues; pay transparency compliance gap | Fractional HR retainer (15–30 hours/month) with dedicated consultant who has professional services experience | $3,500–$6,500/month |
| 100+ employees | HR generalist or HR manager needed; fractional CHRO for strategic workforce planning | In-house HR generalist ($85K–$115K) supported by fractional CHRO or consulting firm for specialized needs | $100K–$160K+ annually |
When evaluating an HR partner for your A&E firm, look specifically for experience with professional services and technical firms—not just general small business HR. PEO exemption nuances, partnership track design, and billable-hour workforce dynamics require sector-specific experience.

Frequently Asked Questions
Are all engineers exempt from overtime pay in Ontario?
No. Only individuals who are currently licensed as Professional Engineers (P.Eng) by PEO or another provincial engineering association are exempt from the ESA’s maximum hours of work and overtime pay provisions. Engineers-in-Training (EITs), engineering technicians (CET), engineering technologists, and all non-licensed technical staff are entitled to overtime pay at 1.5x after 44 hours per week.
Can an architecture or engineering firm use non-compete agreements in Ontario?
Generally, no. The Working for Workers Act, 2021 voided non-compete agreements for virtually all Ontario employees. The only exceptions are C-suite executives (CEO, CFO, COO, CTO) and individuals who sold their business and became an employee of the purchaser. Instead, firms should use well-drafted confidentiality agreements, IP assignment clauses, and narrow non-solicitation provisions.
Does the Pay Transparency Act 2026 apply to architecture and engineering firms?
Yes, if the firm has 25 or more employees in Ontario. As of January 1, 2026, all publicly posted job opportunities must include the expected compensation range, and that range cannot exceed $50,000. Any use of AI in applicant screening must be disclosed. Violations carry penalties up to $100,000.
Do we need to track hours for our licensed engineers?
Strictly speaking, licensed P.Eng employees are exempt from ESA hours of work maximums and overtime pay, so you are not legally required to track hours for ESA overtime purposes. However, you should still track hours for project costing, billing, and psychological safety reasons (burnout monitoring). If any staff member’s licensing status is uncertain, track hours until confirmed.
How does PEO credential tracking work as an HR obligation?
Employers are responsible for verifying that staff who use the P.Eng title or stamp engineering work products are currently licensed by PEO. PEO licences can be verified through PEO’s public directory. Employers should create a recurring annual verification process for all stamp-holding employees. A lapsed P.Eng employee who stamps drawings creates professional and legal liability for the firm, regardless of whether the employer was aware of the lapse.
