Yes. It would be helpful. It's one of my recommendations. Consultant lobbyists are currently required to disclose any entity that carries out lobbying activities or that has an interest in lobbying.
Employers, including corporations and organizations, are under no obligation to disclose the source of funding for lobbying activities. This could become an obligation. In the provinces, the disclosure threshold is $1,000 for anyone who gives more than $1,000 in funding, or more than $750 in Ontario.
