In retirement he continued to advocate for the advantages of human spaceflight in building space infrastructure for monitoring the planet and for communications.<ref>{{cite web |last1=Garneau |first1=Marc |title=When it comes to space, Canada has always reached for the stars |url=https://www.theglobeandmail.com/opinion/article-when-it-comes-to-space-canada-has-always-reached-for-the-stars/ |publisher=The Globe and Mail |access-date=1 April 2025 |date=4 October 2024 |quote="going to space is about much more than humans living on a space station or going to the moon or eventually to Mars. It’s also about building the invisible space infrastructure that helps us monitor what is happening to our planet, communicate with each other, predict the weather, measure our precise location, and understand the origins of our solar system and, perhaps, even of the universe."}}</ref>
