Canadian First World War veteran William 'Duke' Procter will be remembered in his home province of British Columbia on Monday.

Flags are flying at half-mast from sunrise to sunset at the Legislative Buildings and at Government House. A memorial service is also planned for Monday morning at St. John's Lutheran Church in Vernon, B.C.

"William Procter was a proud veteran who will be remembered by British Columbians as a man who served his country honorably and also lived his life fully," B.C. Premier Campbell said of his province's last surviving veteran of the First World War.

Procter was 106 when he died last week.

Born in Mable Lake, British Columbia on August 18, 1899, Procter volunteered for the army as a teenager.

When he signed on in 1916, however, he was deemed too young for the active duty he craved. Instead, he was deployed to a British bush camp where he cut timbers to be used in the trenches at Vimy Ridge.

As a member of 172nd Rocky Mountain Rangers Infantry, he remained in England for three years before returning to B.C.

Campbell said Procter's was a fitting contribution for a West Coast native.

"It was, in a way, a uniquely British Columbian contribution to the war effort that suited a young man from a community like Mabel Lake," Campbell said. "It is men like William Procter that built this province, that preserved the freedom we all cherish, and that make us all proud to be British Columbians."

According to Veterans Affairs, Procter's passing leaves just three known surviving Canadian veterans of the First World War.

"The passing of Mr. Procter reminds us of how important it is to honour and remember those who have served our nation," Minister of Veterans Affairs Albina Guarnieri said last week.

"Too soon, sadly, our country will no longer have Veterans from the First World War. The Year of the Veteran is coming to an end but our debt of gratitude continues and we will never forget."

Despite never having seen action on the frontlines, Procter was nevertheless a decorated soldier.

In 2004, he was awarded the Queen's Golden Jubilee Medal given to Canadians who, over the past 50 years, have made an outstanding and exemplary achievement or service to help create the Canada of today.

A faithful participant in annual Remembrance Day ceremonies, Procter -- who famously celebrated his 100th birthday skydiving -- was scheduled for hip surgery on Nov. 11 this year. He had since caught pneumonia and suffered a small stroke.
