Provincial licensing & certification
| Jurisdiction | Requirement |
|---|---|
| Federal | No federal consulting licence. Securities/financial advice requires registration with provincial securities commission (IIROC/ MFDA). |
| Ontario | No general consulting licence. P.Eng. (Professional Engineer) via PEO for engineering consultants. CMC (Certified Management Consultant) via CMC-Canada optional. |
| British Columbia | No general licence. P.Eng. via EGBC. CMC-BC membership optional. |
| Québec | No general licence. OIQ for engineers. CGC (Conseillers en Gestion et en Communication) for management consultants if using reserved title. |
| All provinces | CPA (Chartered Professional Accountant) for accounting/tax consultants — regulated provincially. CFA, PMP, CMC designations: professional dues deductible. |
Trade-specific deductible expenses
- Professional designations & dues — CMC, PMP, CPA, CFA, CHRP, P.Eng. exam fees and annual membership dues: fully deductible
- Client entertainment — meals and entertainment with clients or prospects: 50% deductible (ITA s. 67.1). Must be business-related with receipt documentation
- Conference & speaking travel — transportation, accommodation, conference fees: fully deductible if business purpose. Meals at 50%
- Subcontractor payments — common in consulting (specialist brought in for a project): fully deductible; issue T4A if any subcontractor receives > $500 in the year
- Retainer income recognition — for accrual-method consultants, recognize revenue when earned (services performed), not when the retainer is paid. Cash-basis consultants recognize when received
- Professional corporation — eligibility varies by province. Ontario permits professional corporations for consultants holding certain designations (e.g., CPA, P.Eng.). Cannot use standard CCPC structure if providing regulated professional services
- Home office — most consultants work from home; claim proportional share if primary workplace
- Research subscriptions — Gartner, Forrester, IBISWorld, industry reports: deductible
- Liability insurance — E&O / professional liability: fully deductible
- Coaching / peer advisory groups — EO, Vistage, TAB membership fees: deductible if business-related
GST/HST
Consulting services to Canadian clients are standard-rated GST/HST. Retainers: if you receive a $20k retainer in December but perform the work in January, cash-basis consultants report it in December; accrual-basis in January. Be consistent year-to-year. Foreign clients: generally zero-rated exports. Subcontractor payments are not taxable supplies you make — the subcontractor charges you GST/HST if registered, and you claim it as an Input Tax Credit.
WSIB / WCB coverage
Consulting is not construction-classified; WSIB/WCB is not mandatory. Optional coverage available. If you embed subcontractors on client sites, verify their coverage status — joint liability can arise in Ontario and BC if an uninsured subcontractor is injured.
CRA audit focus for this trade
What gets flagged
- PSB reclassification — single client > 80% of revenue, especially long-term (2+ years) embedded engagements
- Retainer revenue recognized in wrong year (cash vs accrual mismatch)
- Client entertainment claimed at 100% instead of 50%
- Personal memberships (golf clubs, social clubs) claimed as business
- Subcontractor payments without T4A slips or contracts
- Travel to conferences with no clear business link to current client work
- Professional corporation used for non-regulated consulting (province-specific rules)
