Obituary of Arthur Dempster

June 24, 1943 – Belfast, Ireland

November 15, 2023 - Calgary, Alberta


Arthur Dempster, passed away on Wednesday, November 15, 2023, at the age of 80 years.


Arthur was born in Belfast, Ireland on June 24, 1943. He immigrated to Canada in 1973, marrying Linda Dempster (nee Mercer) in 1975 in Belfast. He and Linda moved to Calgary, AB in 1990.


Arthur enjoyed simultaneously cheering on and booing the Toronto Maple Leafs, playing pool, and almost always winning against his sons and son in law. Arthur also had a love for animals, so much so he fostered dogs and cats from the Calgary Humane Society for more than 10 years. Any time a family pet passed he was the first member of the family asking for another. Some of Arthurs favorite memories are with his family and extended family vacationing around the world, namely Europe with the Mercer clan.


He will be most remembered for his sense of humor, wise cracks, and inability to ever actually retire. Arthur worked up to a few days prior to his sudden passing.


Besides his loving wife, Arthur is survived by his one daughter and one son-in-law, Michele and Mark Semon Calgary, AB; two sons and one daughter-in-law, Jason and Keri Dempster, Christopher Calgary, AB; three grandchildren, Jordan, Logan and Gabriel, Calgary, AB.
