Human Resources jobs in Oakville, ON

Position Summary

The Payroll and Benefits Manager leads accurate, compliant, and timely payroll and benefits administration across ASI Group of multi-national companies. This role owns payroll processing for both unionized and non-union employees across multiple provinces and countries, manages group benefits and retirement savings plan (RSP) administration, and builds the scalable payroll infrastructure needed to support a growing, multi-entity organization. This is a hands-on leadership role: the successful candidate will both manage payroll operations directly and build the processes, controls, and reporting that don't yet exist.

Key Responsibilities

Payroll Operations

• Maintain, verify and process payroll records, including new hires, terminations (records of employment), salary changes and deductions.
• Process accurate, on-time payroll for all employees across Canada and the United States, ensuring compliance with each jurisdiction's Employment Standards Act, State labour laws, and prevailing wage reporting requirements; while accurately allocating payroll labour costs to the appropriate projects, cost centres, and departments to support project costing and financial reporting.
• Administer payroll for unionized employees in accordance with applicable collective agreements, including overtime rules, shift premiums, and distribution/equalization requirements.
• Oversee overtime authorization and tracking processes, working with operations leaders to ensure hours are accurately recorded and approved.
• Process employee reimbursement ensuring they are accurately recorded and approved.
• Process and Manage vacation accrual, statutory holiday pay, and leave-related pay adjustments in line with company policy and applicable legislation.
• Process and reconcile government remittances in compliance with federal and provincial regulatory requirements; coordinate with Accounts Payable to facilitate payment processing.

Benefits, RSP & Union Administration

• Administer group health benefits enrollment, changes, and terminations for eligible employees.
• Administer the company Retirement Savings Plan (RSP), including enrollment, contributions, and employee inquiries.
• Serve as the primary point of contact for benefits providers and brokers and support annual renewal and plan design discussions.
• Reconcile union dues and prepare remittance submission

Compliance & Controls

• Maintain compliance with employment standards, tax remittance, and reporting obligations across all jurisdictions of operation.
• Maintain accurate, audit-ready payroll records and personnel file standards in coordination with HR.
• Partner with Finance on payroll-related journal entries, accruals, and month-end close activities.
• Support internal and external audits with timely, accurate payroll and benefits documentation.
• Manage workers' compensation administration, including claims coordination, premium remittances, and compliance with provincial and state workers' compensation board requirements.

Process Improvement & Systems

• Act as a key hands-on contributor to the HRIS/payroll system implementation, including vendor configuration, data migration, testing, and go-live support.
• Serve as the internal payroll subject-matter expert during system selection and implementation, translating payroll/compliance requirements into system configuration decisions.
• Build standardized, documented payroll and benefits processes to replace ad hoc or manual workflows.
• Identify and implement process improvements to reduce manual effort and error rates as the organization scales.

Qualifications

• 5+ years of progressive payroll experience, including multi-provincial payroll.
• International full-cycle payroll knowledge is highly valued; experience with US and Canadian payroll requirements is a strong asset given our multi-country/entity operations.
• Experience administering payroll in a unionized environment, including collective agreement interpretation, is required.
• Payroll Compliance Professional (PCP) or Certified Payroll Manager (CPM) designation preferred.
• Strong working knowledge of HRIS and payroll systems is essential; comfort configuring, troubleshooting, and optimizing these systems is a core requirement of this role, not a peripheral skill.
• Direct experience as part of an HRIS/ERP or payroll system implementation team (selection, configuration, data migration, testing, or go-live) is a significant asset.
• Experience managing a team is an asset, but not required
• Experience with group benefits and RSP/pension plan administration.
• Working knowledge of Employment Standards legislation across Canadian provinces; familiarity with international labour/payroll requirements an asset.
• Strong attention to detail, discretion with confidential information, and comfort operating in a fast-paced, evolving environment.

• Standardized payroll reporting that gives employees and management clear, timely visibility into hours, overtime, and pay-related data.
• Benefits and RSP administration runs smoothly, with employees able to get timely answers to enrollment and claims questions.
• Meaningful progress on HRIS/payroll system implementation, from vendor configuration through to go-live.
• Proactively identifies and solves problems, takes initiative, and steps in where needed to address challenges and drive positive outcomes. Acts independently while knowing when to collaborate or escalate.
