On June 17, 2005, an incident occurred at a conference in Montreal regarding the subject of Haiti, at one point during the conference, Pettigrew was splashed with a red substance by Yves Engler, a political activist associated with the group "Haiti Action Montreal". As Engler threw the red substance on Pettigrew, he shouted "Pettigrew lies, Haitians die". Engler claimed that the red paint was meant to symbolize the blood on the hands of the Canadian state due to Canada's involvement in Haiti. Pettigrew told police that he wanted full charges pressed against Engler. However, a couple of days later, Pettigrew suddenly decided to drop all charges.
