This job posting reflects a new vacancy within the organization. The position is active and intended to be filled as part of our current staffing needs.

Did you know that 34,000+ Canadians are directly employed in the recycling industry? Interested in becoming part of Canada’s workforce that’s shaping our environment?

Here’s what we do…
CMI sources and processes recycled ferrous and non-ferrous metals across North America to ensure they do not end up in a landfill or go to waste. Our recycling stream ensures that all the ferrous and non-ferrous metals that enter our yards will create something new again!

At CMI, we do things a bit differently. There is no old-fashioned hierarchy. Instead, we work as self-sufficient, autonomous teams that solve the problems. You will get tons of guidance and support from talented, super-smart colleagues all over CMI. Powered by passionate people, we bring together the right teams with the right skills – offering experience and expertise to employees so they can operate their day-to-day confidently and successfully.

We are looking for a driven and committed candidate who exhibits enthusiasm for performing accounting receivable activities and can elevate the receivable role to the next level by thinking out of the box and applying analytical and strategic thinking. This position will be integral to a passionate and dynamic team that values growth, innovation, and collaboration.

Review and manage AR accounts and report on account standing.
Maintain a database of customers, including changes to ensure completeness and accuracy.
Support month-end closing procedures.
Provide a positive experience for internal and external customers and consumers.
Ensure that there is a constant awareness of waste reduction with the most efficient use of time and elimination of nonvalue-added activities.
Additional tasks as requested.

Safety

All tasks must be completed safely in compliance with regulatory and legislative guidelines and company health and safety policies and procedures.

Continuous Improvement

To constantly challenge the current methods and techniques in a controlled manner that will provide a superior, more efficient, and improved result.

1 - 3 years of previous experience in Accounts Receivable function
Excellent English communication skills (written and verbal)
Advanced computer skills with Microsoft Excel

Respond to tight deadlines during regular and peak periods and to last-minute demands and requirements
Ability to multi-task, organize, detail-oriented, and prioritize tasks
Strong judgment and decision-making ability
Possess analysis and problem-solving skills
Ability to work with little supervision

Working Conditions while performing the job:

The position is performed in an office environment.

Compliance & Transparency
In accordance with Ontario’s pay transparency requirements, interviewed candidates will be informed when they are no longer under consideration for this position. Communication regarding application status may be provided through email or through your online applicant profile (if applicable).

Use of Artificial Intelligence
We may use artificial intelligence tools to assist in screening and assessing applications for this role. All hiring decisions are made by our Talent Acquisition team.

At CMI we are committed to fostering an inclusive equitable workplace, free of bias and discrimination, where everyone feels valued, respected, and supported.
