Suppliers cannot bid on City of Toronto solicitations without being fully registered on SAP Ariba. Unregistered suppliers are encouraged to complete their registration to initiate or continue doing business with the City.

SAP Ariba is the City of Toronto’s chosen e-bidding solution. The tool makes it easy for suppliers to download solicitations documents free of charge through the SAP Ariba Discovery Portal, and upload more complete bids because of the easy to follow workflow. The Supplier Lifecycle Performance Module (SLP) went live on October 1, 2021. This cloud-based solution provides suppliers with an opportunity to manage and update profile information anytime from anywhere the internet is available. The opportunity to collect relevant supplier data also supports the City’s communication and procurement related programs.
New suppliers who have not previously registered with the City, and who are interested in viewing and bidding on City solicitations can register by going to the City of Toronto’s Registration Page.

Solicitation documents and Notices of Intended Procurement will continue to be advertised on the City website using the Online Call Document System. An SAP Ariba research posting link within the advertisement will direct you to the SAP Ariba Discovery portal. To help suppliers become familiar with the SAP Ariba registration and response experience, please access the materials in the SAP Ariba Supplier Training Guide and Mock Solicitations section.

For more information, please visit the SLP Information Sessions section.

Buying Groups

The City is a member of the Sourcewell buying group.

The City is also able to access the Province of Ontario’s Vendors of Record and the Federal Government’s Cooperative Procurements. See the Cooperative Purchasing Process for how to access those types of cooperative procurements.

As a supplier for the City of Toronto, the first step you need to take to bid on solicitations that are posted on the Ariba Discovery portal is to register your company and identify your interest in City business.

To register, go to the City of Toronto’s Registration Page, and follow the instructions. Please take into consideration that there is a three-day processing time to approve registration.

If you are already registered on the SAP Ariba Network, you will need to go to the Registration page to register your account with the City. Once you have registered, please note that you will receive electronic notifications when public Solicitations (Request for Proposals, Request for Quotations, Request for Tenders, etc.) are issued for those commodities that are listed on your profile.

To view Notices of Intended Procurement, suppliers can also visit the Online Call Document System, as SAP Ariba only provides notifications for live solicitations.

Please see the “SLP Information Sessions” section below to learn more.

The training guide includes detailed information about how to register and provides training materials to support testing the mock Request for Tender, Request for Quotation and Request for Proposal.
