"I’ve had the honour and privilege to work closely with Nick Leak on many occasions over the last five years, both as a colleague in the Strategic Futures and Concepts portfolios and as a teammate in the Defence Force Structure Review mission. It has been an extreme pleasure to be associated with someone who shared an equal passion, dedication and intellect for these critical strategic subjects and one who keenly focused on the common good of the Canadian Forces and Department of National Defence. An indefatigable, resolute and innovative strategic thinker in both depth and breadth of subject, Nick Leak epitomizes the strength of character and mind that is demanded by the Profession of Arms. It was an absolute pleasure to serve with him lo these many years and I fervently hope that our professional paths cross again in the future."
