Best known for painting dramatic landscapes in acrylic and oil, Squires also produced major work in sculpture, lithography and stained glass.
Born in Change Islands, Newfoundland, Gerald Squires moved with his family to Toronto, Ontario at the age of twelve.
He exhibited his work in Toronto in solo shows such as St. Francis of Assisi and Related Subjects, The Canticles of St. John of the Cross, and The Wanderer Series.
In the early 1980s, he created several major works for Mary Queen of the World Church, a process chronicled in the film The Newfoundland Passion by Arnold Bennett.
"I Heard the Birch Tree Whisper in the Night", a one-hour documentary film capturing Squires' life and completion of his final painting, was aired on CBC television in 2017.
