Background: The two-spotted bumble bee, Cresson, 1863 (Hymenoptera, Apidae), is a common species in central North America, with few published records of this species in Canada west of Ontario or east of Quebec.

New Information: Based on recently collected specimens from Saskatchewan and confirmed records posted to iNaturalist (https://www.inaturalist.org/) in the past 10 years (i.e. since 2013), we provide evidence that this species has only recently expanded its range in Canada, westwards into the Prairies Ecozone (Manitoba, Saskatchewan) and east into the Maritime Provinces (New Brunswick, Nova Scotia, Prince Edward Island).
