Ian was born in Winnipeg, Manitoba on August 24, 1935.
He is predeceased by his father (Colonel) Malcolm Isbester, mother Isobel Tait Isbester, brother Andrew Isbester and brother Fraser Isbester.
Ian leaves brother Malcolm "Mac" Isbester (Marg), sister-in-law Jackie Isbester of Hamilton, nieces and nephews Jamie Isbester (Jennie), Katie Isbester (Kees), Andrea Isbester Malcolm (Doug), Andrew Isbester (Michelle) and David Isbester (Nicole), as well as 11 great nieces and nephews, all of whom he treasured and spoiled.
Ian was a graduate of Royal Military College, Carlton University, Bachelor of Science, Engineering, and then on to his MBA at Western University.
Ian's military career took him to every part of the world, all of which he explored, adopted and devoured.
Many long lasting friendships were made during that time, especially National Defense College days.
Ian's last posting was Ottawa where he remained until moving back to Napanee in 2016. His days at Ambleside Drive and the condo association forged a whole new avenue for relationships as he spent many years on the Condo Association Board.
Ian's summers were spent on the Bay of Quinte, Long Reach, Sans Souci Road, where he built a summer home on the property that had been the family cottage purchased shortly after his dad had passed away.
His job there, aside from enjoying the venue, was to be the long standing secretary of the Napanee Campground Association.
Cremation has taken place. Interment will be in Ottawa at the Beechwood Cemetery.
Donations made to the Lennox & Addington Humane Society are welcomed by the family.
