A Day in the Life (What you will do here):

• Takes a hands-on role in processing payroll for a subset of legal entities, given the tight turnaround and high employee volume involved in each payroll cycle; balances direct processing with supervisory oversight of the broader team


• Processes and audits multi-provincial payroll (salaries, benefits, garnishments, taxes, deductions). Keeps HRIS records accurate for reporting and audits.


• Owns payroll compliance: year-end filings (T4, T4A, T2200, ROEs) and government remittances (Health Tax, WSIB, CPP) by province.


• Manages payroll records retention per policy. Processes off-cycle payments as needed. Removes terminated salaried employees from auto-pay promptly.


• Serves as the primary point of contact for payroll matters, resolving cases quickly with a focus on superior customer service.


• Works with Finance and Accounts Payable on GL reconciliations, new payroll code/GL mapping, and updates to employee banking and garnishment details.


• Leads, mentors, and trains Junior Payroll Specialist.


• Reviews and approves final payroll before it goes to the Controller. Keeps supporting documents for audit. Acts as backup for the Payroll Specialist.


• Leads payroll system enhancements and special projects, partnering with IT, HR, and Finance stakeholders.


• Investigates payroll discrepancies and fixes them at the source. Is the escalation point for tough payroll, tax, and compliance issues, including CRA rulings and audits.


• Drives SOP standardization, automation, and continuous improvement in payroll. Upholds Sentrex's Mission, Vision, Values, and Brand.


• Other duties as assigned by your manager

What you need to ensure you are set up for success:

• Bachelor's degree in Accounting, Business Administration, Human Resources, similar field, or equivalent experience. 


• 7+ years of progressive payroll experience, including mentoring or reviewing the work of other payroll staff, in a fast-paced, multi-entity environment. 


• PCP Certification is required. CPM Certification is strongly preferred, reflecting the seniority and scope of this role. 


• Strong knowledge of multi-provincial payroll in Canada: preparation, balancing, internal controls, payroll taxes, and the full payroll cycle (banking, journal entries).


• Demonstrated experience leading payroll system implementations, upgrades, or process improvement/automation projects. 


• Strong Excel and payroll software skills (VLOOKUP, pivot tables, system setup/testing). Power Query, macros, and Workday experience are assets. 


• Strong organizational, analytical, and problem-solving skills, with excellent attention to detail and the ability to meet deadlines and prioritize competing projects. 


• Strong business/financial acumen and superior interpersonal, written, and verbal communication skills. 


• Bilingual (English/French) considered an asset.

What makes you a great fit for this team: 

• Your commitment to providing a high level of service to your internal and external clients.


• You are highly adaptable with a track record of success during times of growth and organizational change.
