Loss Prevention Clerk – Costco – Markham, ON

Costco’s Markham warehouse on Kirkham Drive is looking for a Loss Prevention Clerk to help protect company assets and maintain a safe shopping environment. This is a hands-on, active role that puts you at the front line of retail security and loss prevention — ideal for someone who thrives on keeping people safe and upholding the highest standards of integrity.

Day to day, you’ll be walking the warehouse floor and perimeter, monitoring for safety and security concerns, identifying potential theft, and working closely with warehouse management and law enforcement when needed.

You’ll also prepare reports, maintain evidence files, and coordinate with local law enforcement — including testifying in court when required.

Beyond direct theft prevention, this role involves coaching and educating warehouse team members on loss prevention policies, communicating with neighbouring Costco locations and local businesses about theft trends, and identifying shrink reduction opportunities within operations. Strong judgment, discretion, and a thorough knowledge of relevant Canadian legislation are essential in this position.
