During this time as a student she encountered both Barry Truax and R. Murray Schafer, and began working for Schafer as part of the World Soundscape Project at Simon Fraser University (SFU) in 1973. She later enrolled as a student in the communications department and completed her thesis, entitled "Listening and Soundmaking: A Study of Music-As-Environment," for a Master of Arts degree in 1988; she taught acoustic communication at Simon Fraser until 1990. In 2024, Westerkamp received an honorary doctorate from SFU in recognition of her contributions to acoustic ecology, music composition, and sound studies.

Westerkamp became a naturalized citizen of Canada in 1975. In 1972, she married the Canadian poet and playwright Norbert Ruebsaat and collaborated with him on a number of projects before their separation. She later maintained a long-term relationship with Peter Grant, to whom her 1997 piece Talking Rain is dedicated; Grant died in 2014.
