Doing Business with OPG

​We appreciate your interest in doing business with OPG. We ask suppliers to meet OPG supplier requirements and provide the requested information about your company to allow a better understanding of the nature and scope of the goods and services sold. We also encourage suppliers to explore business opportunities with Indigenous businesses.

As part of our planning cycle, OPG continuously assesses its strategic sourcing. As part of our assessment, your company’s profile and associated information are important should our review reveal necessary changes in our sourcing capability, or to address a specific internal client request. We welcome your response to help us evaluate available supplier market options.

Occasionally OPG may post procurement opportunities. Interested suppliers are encouraged to view the summaries on Ariba Discovery.

If you are a Service Provider there is a requirement to register your business with ISNetworld.

In order to do business with OPG, suppliers must meet OPG's qualification standards. New suppliers must register their company profile with OPG for an evaluation by using the Registration Form on the Ariba Network and completing the required fields. There is no fee for completing this form; your file will be kept on the sourcing database indefinitely. If you already have a profile on the network, you can request a trading relationship with OPG.

Purchasing Agents will search the registered supplier’s database when there is a need to purchase services or materials. Purchasing Agents will contact businesses whose profile qualifications meet selection criteria and may request clarification, additional information, or a proposal or quotation in response to a formal solicitation.

Please note that no promise of contract(s) is implied by being registered with Ariba. Contract awards follow OPG’s established procedures for competitive bidding, evaluation and negotiation. The steps in the competitive bidding process include a thorough financial and quality assurance evaluation to ensure suitability with OPG’s standards of excellence.
