Navigator Ltd. is a Canadian public relations, crisis management, lobbying, and polling company based in Toronto, with offices in Ottawa, Calgary, Edmonton, and Moncton, Canada.

[14] During the 2006 Canadian federal election a former Navigator employee and Preston Manning staffer named Patrick Muttart was a campaign advisor for Stephen Harper and was credited with being one of the key figures behind his electoral victory that year.

[18] A high-profile client of Navigator in 2009 was Michael Bryant, the former Attorney General of Ontario and Government House Leader, who hired the firm after facing charges for the death of a cyclist, Darcy Allan Sheppard.

[22] Harper's office was then criticized by opposition politicians for revealing that an investigation had been taking place, as they are supposed to remain private while in progress.

[25] However, a subsequent investigation did find that Will Stewart, a consultant with Navigator, did break lobbying ethics rules by organizing the fundraiser for Raitt in September 2009 while also acting as lobbyist to the government she represented.

[39] Special rapporteur on foreign interference and former governor general of Canada, David Johnston hired Navigator in 2023, but the partnership ended after a week.
