Clark worked as part of SportWORKS, a partner of CSC, that looked to develop sport with local projects and initiatives to build communities in Canada.

He was the facilitator of SportWORKS officer training sessions, where he educated the next generation of workers in these programmes.

Ryan Pelley, the programme manager at SportWORKS, was among the first to pay tribute to Clark.

"Raymond was impactful in the lives of our SportWORKS officers," he said.

"This was because of his genuine interest in developing all of us, not just as professionals, but also as individuals."

Clark was also a teacher for 20 years between 1969 and 1989 as part of CUSO International, formerly known as Canadian University Service Overseas.

There he worked as field staff and later as a regional director for the Caribbean, East and West Africa and the South Pacific.

Later, he worked at the CUSO headquarters in Ottawa.

He also spent time working in Toronto with homeless people who suffered from mental illnesses, while in the early 1990s he was a consultant at the International Centre for Ocean Development in Halifax in Nova Scotia.

After retiring in 1998, he continued to consult with the United Nations Development Programme in intercultural training.

Former SportWORKS programme manager Colin Whitmee worked closely with Clark in the past and credited his former work colleague's ambitions.

"Raymond often said that his ambition in life was to change the world and his means of doing that was by influencing young people and empowering them to make a difference," he said.

"Raymond had a profound impact on my life, and I know that is the case for countless others who worked in CSC's international programmes over the years.

"Raymond had an ability to read and connect with people like no one I've ever met.

"I first met him as a participant in one of his workshops, which later evolved into co-facilitator, mentor and above all else a friend."
