A scathing ethics probe raised questionable conduct of an unnamed Greenbelt consultant dubbed “Mr. X.” He has been identified to the Star as former Clarington Mayor John Mutton, seen here with Premier Doug Ford. Mutton stressed his work on the issue wasn’t as a lobbyist and he said he did not know who “Mr. X” was.


Developer Peter Tanenbaum had long wanted to build houses on an 86-acre plot of Greenbelt land he owned in Clarington, so in 2022, he hired two consultants to help.

One was Nico Fidani-Diker, who previously worked as executive assistant to Premier Doug Ford and was now a registered lobbyist with multiple developers as clients.
