PortsToronto is a public corporation. As such, it has a board of directors, appointed under regulations of the "Canada Marine Act" and the Letters patent of the agency. As originally set up, the Board was seven members, and was made up of one member appointed by the Government of Canada, one by the City, one by the Province of Ontario, and four by the federal government in consultation with the classes of users mentioned in the letters patent. The federal government changed the Letters Patent of the TPA in 2008 to modify this to nine members. The federal Minister of Transport now nominates seven of the nine members, one as the federal government representative and six "in consultation with the users selected by the Minister, or the classes of users mentioned in Schedule D of these Letters Patent."
