The purpose of the Vendor Performance Evaluation Program (VPEP) is to provide an evaluative record, both positive and negative, of a vendor’s performance on any given service or project that has been awarded to a vendor by the City of Sarnia.


The VPEP is a standardized internal tool used to encourage our vendors to improve their performance. It will be used consistently across all divisions to assess performance, and when considering a vendor’s eligibility for future awards.

The VPEP evaluations are to be conducted by the City team members who are involved in the oversight, management, or utilization of the vendor’s services.

Process Chart

Follow-up Meeting with Vendor

As part of the evaluation process, the Requisitioner and Requisitioner Supervisor, should meet with the vendor representative to review the evaluation.

This will permit an opportunity for the vendor to gain insight on any negative scoring related to the evaluation so corrective action can be achieved.


In the event that a vendor does not agree with the evaluation score, they must submit objections in writing, with supporting evidence, within five (5) business days following receipt of the report to the attention of the Purchasing Manager.

Based on the information provided, it shall be at the City’s sole discretion whether the score shall be amended and/or a replacement evaluation be issued.


In the event performance ratings warrants the suspension of a vendor, a notice must be submitted to the vendor by the affected Department outlining the:

  • Evaluation score
  • Background information supporting suspension

Suspension can also be warranted outside of the performance rating if they neglect to comply with, for example:

  • Health and Safety provisions of the Occupational Health and Safety Act
  • Failure to pay sub-contractors resulting in liens being filed against a project

Other than contracts / sub contracts under which the vendor is already performing work at the time of suspension, the vendor is not eligible to bid on City contracts, and may not perform work as a subcontractor for the duration of the suspension.  The suspension of the vendor also applies to:

  1. Any legal entity that is affiliated with the vendor within the meaning of the Business Corporations Act;
  2. Any related person of the vendor ownership within the meaning of the Business Corporations Act;
  3. Other legal entities having the same operating mind as the vendor, as determined in the consultation with Legal Services.

After the suspension period, the vendor may bid on City projects and / or work as a sub-contractor.

The term of suspensions will be variable based on the term of service, and scope of the projects.
