Ontario’s employer health tax adds a quirk on top — the rate is chosen using payroll *before* the exemption, not after it. EverStone runs payroll for [Mississauga businesses](https://www.everstonecpa.com/accountant-mississauga) remotely, on a written fixed scope. [Get My Fixed Quote](https://www.everstonecpa.com/book-online)[Ask a Free Question](https://www.everstonecpa.com/quick-question) **Quick answer:** Mississauga employers remit income tax, CPP and EI to the CRA and pay Ontario employer health tax on Ontario remuneration. The rate is selected from a graduated table using total payroll before the exemption, then applied to payroll after the $1,000,000 exemption is deducted. WSIB coverage is separate again. For a Mississauga business, payroll is included in monthly bookkeeping from $300 a month; a payroll-only engagement is quoted by headcount and pay frequency. Payroll covers the source deductions for CPP, EI premiums and income tax, the remittances to the CRA, the year-end T4 and T4A slips, the RP account in My Business Account, and Records of Employment when staff leave. Updated October 2026 . ## Payroll in a city of shifts, drivers and warehouses The City of Mississauga lists advanced manufacturing and smart logistics among its key sectors, and the city is home to Canada’s largest airport. For a small employer in that economy, payroll is rarely a single salaried pay run. It is hourly staff on rotating shifts, overtime that varies with volume, shift premiums, drivers who may be employees or contractors, temporary staff in the busy season, and a turnover rate that means Records of Employment are filed regularly. Each of those features is ordinary on its own. Together they make a payroll where small errors repeat every two weeks until someone notices. We set the payroll up properly at the start: each employee’s TD1 forms on file, pay codes that separate regular, overtime, vacation and public holiday pay, taxable benefits coded so they reach the T4, and a remittance calendar built from the schedule the CRA has assigned to your RP account. Then each run is reviewed before it is approved rather than corrected afterwards. ## The Ontario employer health tax rate is chosen before the exemption, not after Ontario’s employer health tax is graduated rather than flat, and the order of operations is where employers lose money. You select your rate from the band table using **total Ontario remuneration before any exemption is deducted**. Only then do you subtract the exemption and apply the chosen rate to what remains. Reading the table the intuitive way — deducting the exemption first, then finding your band — puts you in a lower band than you belong in and understates the tax. The bands run from 0.98% on [Ontario payroll](https://www.ontario.ca/document/employer-health-tax-eht) up to $200,000, through a series of steps between $200,000.01 and $400,000, to 1.95% on payroll over $400,000. The exemption is $1,000,000. Two further rules matter for a Mississauga business with more than one company. No exemption at all is available where the employer or its associated group has more than $5,000,000 of annual Ontario payroll. And associated employers must file an allocation agreement to share the single exemption between them. A plant or warehouse that adds a second shift can move from under the exemption to over it inside one year, so we track the running total from the first pay run. All of it is tabled with its source on the [Ontario tax facts page](https://www.everstonecpa.com/ontario-tax-facts). ## Group structures are where the exemption disappears Family businesses in Mississauga often grow into more than one corporation: an operating company and a holding company, a second operating company for a new location or product line, a property company that owns the building. The employer health tax exemption belongs to the associated group rather than to each corporation. Without an allocation agreement, each entity can end up claiming a full exemption it is not entitled to, and a group that crosses $5,000,000 of combined Ontario payroll loses the exemption outright rather than having it tapered. The calculation therefore has to be done at group level and then allocated, in that order. Doing it entity by entity and summing the results produces a number that is wrong in a predictable direction. The [associated corporations](https://www.everstonecpa.com/blog/associated-corporations-small-business-deduction) note covers the parallel issue on the corporate tax side. ## Employees, contractors and drivers Logistics and trades businesses regularly work with people who could be employees or independent contractors, and the label in a contract does not decide it. The CRA looks at control, ownership of tools and equipment, the chance of profit or risk of loss, and whether the worker is in business on their own account. A driver who uses the company’s truck, follows the company’s routes and works only for that company looks like an employee whatever the agreement says, and if the CRA reclassifies the relationship the employer owes the CPP and EI that should have been remitted. We review these arrangements before they become a payroll audit question. [Employee or contractor](https://www.everstonecpa.com/blog/employee-vs-contractor-cra-worker-classification) sets out the tests. ## WSIB, and the federal deductions underneath Workplace coverage in Ontario runs through the **Workplace Safety and Insurance Board**, which is entirely separate from the Ministry of Finance and carries its own registration, classification and clearance obligations. It is driven by the same payroll data as everything else but reported to a different body on a different schedule, which is exactly the sort of split that gets missed when payroll is run informally. For a Mississauga contractor or manufacturer, the classification is worth checking, because it sets the premium rate. Beneath both provincial layers, the federal obligations are the same everywhere in Canada. Income tax, CPP and EI are withheld from each pay run and, with the employer’s contributions, remitted to the CRA on the schedule assigned from your average monthly withholding. Ontario also recognizes nine public holidays. Public holiday pay is regular wages and vacation pay from the four work weeks before the holiday week, divided by twenty, which for shift workers with variable hours needs to be calculated rather than estimated. [Payroll remittances and the RP account](https://www.everstonecpa.com/blog/payroll-remittances-canada-rp-account) covers the federal side. ## What is covered - Pay runs with Ontario tax tables applied to Ontario employees - Overtime, shift premiums, vacation and public holiday pay calculated under Ontario employment standards - Income tax, CPP and EI withheld and remitted on your CRA schedule - Employer health tax calculated at group level, with the band selected correctly - Allocation of the exemption across associated employers where one applies - WSIB registration support and payroll reporting - Records of Employment when staff leave - T4 and T4A slips and summaries filed by the last day of February ## Remote, and there is no Mississauga office EverStone is a fully virtual CPA firm serving employers in BC, Alberta, Ontario and Manitoba.

Common questions ## Mississauga payroll questions **How is the Ontario employer health tax rate selected?** From total Ontario remuneration before any exemption is deducted. Once the band is identified, the exemption is subtracted and the chosen rate applies to the remainder. Deducting the exemption first and then choosing a band lands you in a lower rate than you belong in and understates the liability. [Ask about your case →](https://www.everstonecpa.com/quick-question) **What are the Ontario employer health tax rates?** They run from 0.98% on Ontario payroll up to $200,000, through a series of steps between $200,000.01 and $400,000, to 1.95% on payroll over $400,000. The exemption is $1,000,000, and it is scheduled for inflation adjustment on 1 January 2029. **Can every Mississauga employer claim the $1,000,000 exemption?** No. It is unavailable where the employer or its associated group has more than $5,000,000 of annual Ontario payroll — the exemption is lost outright rather than reduced. Associated employers below that line must file an allocation agreement to divide the single exemption between them. **Is WSIB part of the same filing as employer health tax?** No. WSIB is administered separately from the Ministry of Finance, with its own registration, classification and reporting. It draws on the same payroll figures but is a distinct obligation, which is why it is commonly overlooked when payroll is handled informally. **Are my drivers employees or contractors?** It depends on the working relationship, not the contract’s label. Control over the work, who owns the truck and tools, and whether the driver carries any business risk all count. Where the facts point to employment, CPP and EI should be withheld and remitted, and a reclassification later can make the employer liable for both shares. **How is Ontario public holiday pay calculated?** From regular wages earned plus vacation pay payable in the four work weeks before the work week containing the holiday, divided by twenty. Ontario recognizes nine public holidays. For shift staff with variable hours the amount differs for each person, so it is calculated rather than estimated. **Does EverStone have an office in Mississauga?** No. The firm works online. Mississauga employers are served entirely remotely through video meetings, e-signature and secure document exchange, and the engagement does not require anyone to travel. **What does payroll cost for a Mississauga business?** Nothing about a Mississauga address changes the fee. Payroll is included in monthly bookkeeping from $300 a month; a payroll-only engagement is quoted by headcount and pay frequency, in writing, after we review your enquiry. [See the published fees](https://www.everstonecpa.com/pricing). **Do you work with businesses outside Mississauga itself?** Yes. Employers in Brampton, Caledon, Toronto and the rest of Ontario are set up the same way as those in Mississauga: payroll runs remotely, remittances are scheduled, and the fee does not change with the address. ## Related services and local guides The rest of what we do for Mississauga businesses, the nearest large-city page, and the reference pages behind this one.
