During his time as COO, Martin Tremblay was a staunch supporter of non-compete clauses, in large part due to an incident in which Electronic Arts hired away several Ubisoft Montreal employees to the at the time newly opened EA Montreal studio. When Tremblay left Ubisoft in 2006 to become President of Worldwide Studios at Vivendi Games, he was prevented from taking the new position by a court order enforcing the non-compete clause in his Ubisoft contract. Upon Tremblay's departure in 2006, Yannis Mallat, a producer on the Prince of Persia games, became the new CEO, also filling the same roles as Tremblay's COO position.
