Fifty-four new Canadian provincial records of aleocharine beetles (Staphylinidae), including three new Canadian records and one new North American record, are presented. Of these, 33 are new provincial records for Saskatchewan, 14 for Alberta, two for British Columbia, three for Manitoba, two for the Northwest Territories and one for the Yukon Territory. The following are new Canadian records: Trichiusa pilosa Casey [formerly reported from Nova Scotia and Ontario as T. postica Casey], Acrotona recondita (Erichson) and the adventive Palaearctic Atheta nigra (Kraatz), which is also a new North American record. Bionomics information and new locality records are provided. The following new synonyms of Trichiusa pilosa Casey are established: T. atra Casey, T. monticola Casey, T. parviceps Casey, and T. postica Casey. The numbers of Aleocharinae remaining to be discovered in Canadian provinces and territories are discussed.
