Thomas Grantham Norris MC (2) KC was born at Victoria British Columbia (BC), son of John Francis Norris of Montreal and Victoria and Marianne (Lawson) Norris of Charlottetown, Prince Edward Island. He was educated at Victoria BC and at McGill University. Norris served with the 3rd Battery Canadian Field Artillery from 1915 to 1917.

From 1917 to 1918 he was a Lieutenant with the 10th Battery Canadian Field Artillery, 3rd Brigade and was awarded his first Military Cross (MC) for conspicuous gallantry and devotion to duty during operations from September 27th to 30th, 1918. His citation reads in part, as follows: When a shell landed alongside "E" subsection gun, wounding him and three Non Commissioned Officers (NCOs), he saw the NCOs bandaged up and sent to the dressing station, and though his wound was almost painful, stayed with the battery until the night of September 29th when he was finally ordered out by the brigade medical officer. The devotion to duty and coolness under fire, of this officer, has always been an inspiration to the men of this battery.

One month later he was awarded a second MC. His second citation reads in part, as follows: He went forward with a small patrol, keeping in touch with the infantry, under heavy shell fire, and sent back information. One of his men and all of his horses were killed during the day, but he continued on foot and persevered in the task of enabling his battery to support the attack by the information he sent back.

After WW1, Norris was called to the Bar of British Columbia in January 1919 and practiced law with Barnard, Robertson and Heisterman in Vancouver BC. In September 1932 he was created King's Counsel (KC). In WW2, from 1941 to 1945 he was Judge Advocate General for the 21st Army Group. After WW2 he was appointed Judge of the Court of Appeal of British Columbia and the Court of Appeal of the Yukon Territory, Judge of the Court Martial Appeal Court of Canada, and District Judge in Admiralty for British Columbia.

Norris was active as a volunteer in a number of organizations such as Vancouver Board of Trade (President), Vancouver Bar Association (President), and Law Society of British Columbia (Treasurer). In April 1920 Norris married Jean Mary Denovan, daughter of Dr. and Mrs. Howard Judson Denovan of Toronto ON. They had two sons and one daughter. After his first wife died in 1958, Norris married Joan Mary Appleton, daughter of Mr. and Mrs. I.D. Rowe of Penticton BC.
