He grew up in Northern Ontario, which was where he first became interested in nature. As a teenager he was a member of the Royal Ontario Museum's Toronto Junior Field Naturalists.

He retired from the University of Florida in 1999, but remained on the faculty as an Emeritus Eminent Scholar. He was awarded two major awards from the Ecological Society of America, the Mercer Award given to a young scientist in recognition of an outstanding paper in ecology in 1966, and the Eminent Ecologist Award for "outstanding contributions to the science of Ecology" in 1999.

In 2009, he was made an Officer of the Order of Canada "for his pioneering contributions to the field of ecology, notably for his work on ecosystem dynamics, resilience theory and ecological economics". He was founding editor-in-chief of the open access on-line journal Conservation Ecology, now renamed Ecology and Society. He was also the founder of the Resilience Alliance, an international science network. Work Throughout his research, C. S. Holling blended systems theory and ecology with simulation modeling and policy
