Canada C3 was a 150 day marine journey from Toronto, Ontario to Victoria, British Columbia by way of the Northwest Passage. Based on the icebreaker Polar Prince, this expedition brought together a diverse group of Canadians to explore Canada’s coasts while reflecting on the journey’s core themes of Diversity and Inclusion, Reconciliation, Youth Engagement and the Environment. During the expedition’s scientific program, shipboard researchers collected plants and lichens at stops along the journey to add new knowledge on the floristic diversity of Canada. Specimens will be deposited at the National Herbarium of Canada at the Canadian Museum of Nature. In all 1321 collections were made by 42 collectors. The majority of these (922) were made in the Canadian Arctic, and many were gathered from places where no or few botanical collections have been made previously (e.g., Cape Barrow, Nunavut; Tree River, Nunavut). Notable Arctic collections include the Arctic orangebush lichen (Xanthaptychia aurantiaca), a globally rare (G1) species, and a significant eastward range extension of the spruce muskeg sedge (Carex bigelowii subsp. lugens). All Arctic collections will contribute to the museum’s ongoing Arctic floristic research, and all expedition specimens will serve as a scientific legacy to this epic voyage.
