Massey Whiteknife is a Canadian producer, businessman, and entertainer. He is known both under his own name as CEO of the ICEIS Group of Companies, an occupational safety and health and sustainable development consulting firm in the Athabasca oil sands region of Alberta, and as ICEIS Rain, a drag queen and pop singer.
A Cree member of the Mikisew Cree First Nation originally from Conklin, Alberta, he moved to Fort McMurray as a teenager to complete high school. Having faced both childhood sexual abuse and bullying as a teenager because he was gay, he first created the drag persona of ICEIS Rain after being diagnosed with post-traumatic stress disorder during this era. According to Whiteknife, Iceis Rain helped him to become more secure and confident in himself and his business career, and to heal from his childhood emotional traumas.
He later launched the ICEIS Group, now a multimillion-dollar company with interests in health and safety training and environmentally friendly industrial cleaning products. He built his business by telling people that "You can turn me away if I don't do a good job, you can throw me out of the building, but if you don’t give me a chance because of my sexuality, well, that just doesn’t make sense. That way, if I don’t do the job, then you can say at least you gave me a shot." He is also involved in philanthropic ventures, including as an anti-bullying activist and in a non-profit career placement and mentoring program for First Nations people.
With few conventional gay social venues in Fort McMurray, Whiteknife began going out to karaoke bars to perform as ICEIS Rain. He appeared in the 2013 documentary film Oil Sands Karaoke, and is depicted on the film's promotional poster. He also produced the film God's Acre in 2016.
