Hollobon is a life member of the Science Writers & Communicators of Canada (SWCC), formerly the Canadian Science Writers' Association (CSWA). She joined NASW before CSWA was founded in 1971, and served as president of CSWA in 1974-1975.
There are three levels of the Order of Canada - from lowest to highest - Member, Officer, and Companion - and on the strength of her contribution the Committee recommended that Hollobon should be appointed an Officer of the Order of Canada, one of the highest honors a Canadian can receive.
Hollobon's appointment as an Officer of the Order of Canada appears on the website of the Governor General of Canada along with a short citation:
"For her career in journalism focused on increasing the public's understanding of scientific concepts related to health and medical advances."
