The comparison most families make when weighing a private caregiver against a licensed agency is simple: a lower hourly rate vs a higher one from a licensed provider. The private hire looks 40% cheaper. But the hourly invoice rate is only the starting point - and in most cases, it is not the number that tells you the real cost. This guide builds the full cost picture for both options so you can make a decision based on actual numbers, not the rate you see first.
The true cost of private employment
When you hire a caregiver privately, you become the legal employer under Ontario and federal law. This triggers a set of mandatory costs that every employer must pay - whether or not they know about them at the time of hiring.
Employer payroll costs
For every dollar you pay the caregiver, you owe additional amounts to the government:
- Employer CPP contribution: In 2025, approximately 5.95% of the caregiver's insurable earnings, matched by the employer (up to the annual maximum). You pay both the employee and employer share - the employee's portion is deducted from their pay; your portion is additional cost on top.
- Employer EI premium: Approximately 1.4 times the employee's EI premium rate. In 2025, this is approximately 1.96% of insurable earnings - paid by you on top of the wage.
- Vacation pay: Ontario's Employment Standards Act requires a minimum of 4% of gross earnings as vacation pay (rising to 6% after 5 years of service). This is an additional cost per hour worked.
Once mandatory employer add-ons are applied, the real cost per hour rises significantly above the headline wage.
WSIB registration and premiums
If WSIB registration is required for your situation (which it may be for home care workers), WSIB premiums add further cost - typically 2–5% of gross payroll, depending on the risk classification. More importantly, if you are not registered and an injury occurs, you may be personally liable for the full claim - which can far exceed any savings from the private arrangement.
Payroll administration
Unless you manage payroll yourself (which requires software, knowledge of the rules, and time), you will pay a payroll service provider. Payroll processing for a single employee has a recurring monthly cost, plus T4 preparation at year-end.
Recruiting and background checks
When the caregiver is not working out or leaves, you bear the full cost of recruiting again: advertising, screening, interviewing, and a Vulnerable Sector Police Check (plus your time). If care gaps occur during the search, you may need to pay for emergency care at premium rates.
The real hourly cost comparison
For a caregiver working 30 hours per week, consider the full employer cost picture:
- Gross wage (the invoiced hourly rate)
- Employer CPP contributions
- Employer EI premiums
- Vacation pay (minimum 4% by Ontario law)
- WSIB premium
- Payroll administration cost
Real cost: meaningfully higher than the headline wage before any recruiting costs or gap coverage.
A licensed private home care provider includes all of the above in their rate, plus: backup caregiver coverage, clinical oversight, professional liability insurance, managed recruitment and termination, and a care coordinator you can call.
The gap narrows from 40% to approximately 20–35% - and that remaining gap is the price of the infrastructure the agency provides.
The costs that don't show up in hourly rates
The hourly cost comparison also misses several significant risks that are difficult to quantify but real:
- Backup coverage gaps: When a private caregiver is sick or quits, you have no coverage. A single day of arranging alternative care through other means (emergency agency placement, emergency care costs, family member missing work) can erase weeks of savings.
- Injury liability: A serious caregiver injury without WSIB coverage exposes you to a claim that could cost tens of thousands of dollars. This is not a theoretical risk - home care involves real physical labour with real injury rates.
- Employment dispute liability: If you terminate a private caregiver improperly under Ontario's ESA, they can file an employment standards complaint. Wrongful dismissal claims are an additional risk.
Frequently asked questions
Is a private caregiver actually cheaper than an agency when all costs are counted?
The invoiced hourly rate appears lower, but once you add mandatory employer costs (CPP, EI, vacation pay, WSIB, payroll administration), the gap narrows significantly. A licensed provider's rate includes all of these costs plus backup coverage, liability insurance, and care oversight making the true cost difference considerably smaller than the headline rate suggests.
What if the private caregiver agrees to be paid as a contractor?
The working arrangement determines the legal relationship - not the label. If the caregiver works set hours at your home under your direction, CRA and WSIB view them as an employee regardless of any contractor agreement. If you are audited or if the caregiver files for EI, CRA will assess the relationship and assign employer liability accordingly.
What does an agency's overhead actually cover?
Agency overhead funds: employer payroll remittances, WSIB coverage on all caregivers, general liability and professional liability insurance, criminal record checks and vulnerable sector screening, backup caregiver rosters, clinical oversight and care coordination, managed recruitment and replacement, and the administrative infrastructure to run a compliant care operation. These are not soft benefits - each represents a real cost and a real risk transfer to the agency.
When does private hiring make financial sense in Ontario?
Private hiring can make sense when: the care need is very light (companion only, no personal care), the family has employment law expertise and manages payroll properly, the care hours are minimal and irregular, or a trusted person with relevant experience is taking the role. For anything involving personal care, mobility assistance, or dementia support at significant hours, the risk-adjusted comparison usually favours an agency.
Can I get agency quality at a lower rate by negotiating?
Some agencies offer reduced rates for high-volume hour commitments or specific care arrangements. It is worth asking. Rates are not infinitely flexible - agencies have fixed costs they cannot eliminate - but a 5–10% reduction for a long-term, consistent arrangement is not unusual with some providers.
