US Army L-20 53-2829 was delivered April 24 1954. It was one of a number of ex Army Beavers bought by B - M Aviation and stored at Lachute, QC in 1973. Put on the Canadian Register circa 1979 after rebuild, the aircraft remained in the Province of Quebec until sold in 2019 to Clark's Northern Lights Resort.

Former US Army 58-2013 has been with Clark's Air Service since 2015. It's had quite a few upgrades since the Army days.

Originally with Eastern Provincial Airways, this Otter has been flying around Northern Ontario since Green Airways bought it in 1980. The aircraft received a Polish PZL 1000hp engine conversion in the Fall of 1996. Sold to Excellent Adventures in 2016 after a time in storage, the aircraft was added to Clark's Air Service fleet in August 2018 to serve Clark's Northern Lights Resort.
