Lobbyists Registration

Welcome to the Ontario lobbyists registry. You will find everything you need to create an account, file a registration, search the registry and more.

NOTICE: Staff at the Office of the Integrity Commissioner may be working remotely. Please email us at lobbyist.mail@oico.on.ca for assistance on lobbyist registration.

What's New


Lobbyists are responsible for ensuring that the lobbying targets in their registrations are updated following a cabinet shuffle or any changes to ministerial titles and ministry names. To assist lobbyists in keeping registrations up to date, we have created a page that shows the previous and the new lobbying target names.

Lobbying Activity

Lobbyists completing the Lobbying Activity section of the registration form are required to submit a complete description of lobbying activities. Lobbyists are encouraged to consult the Lobbying Activity page for guidance on submitting clear and concise statements that allow the public to easily identify and understand lobbying goals.


The Office has a new way to inform lobbyists about Ontario’s registration and compliance requirements - an email newsletter.

Read previous issues.

The newsletter will be issued up to six times a year. Please subscribe below.

Interpretation Bulletins

The Integrity Commissioner, as Lobbyists Registrar, issues Interpretation Bulletins that interpret specific sections of the Lobbyists Registration Act, 1998. The Bulletins have been revised and new ones have been added. Read them here.
