Pitsiulak was based in Cape Dorset, Nunavut, where he worked as a hunter while making Jewelry sculptures, lithographs, photographs, and large coloured-pencil drawings, the last of which he is best known for. His favorite subjects were Arctic wildlife and scenery, and traditional and modern Inuit culture. His work is presented in private collections and is still shown in galleries. In 2013, the Royal Canadian Mint featured a Pitsiulak drawing of two beluga whales and a bowhead whale on Canada’s 25-cent coin. His work combined traditional motifs with contemporary techniques.

Tim was a hunter and his respect for the natural world and its wildlife was fundamental to his artistic sensibility. Tim was particularly inspired by the whales that frequent the cold, Arctic waters - the beluga and the bowhead - because, as he would say, nobody really knows much about them. The bowhead in particular is a majestic and mysterious creature and frequently he would embellish his drawings of these animals with ‘tattoos’ of ancient artifacts.
