Sending love to Arlette, whom Leo loved so deeply, and condolences to all his friends and family. A sweet and warm man who will be terribly missed.
Leo was a person that thrived on helping and looking out for others. He was like an old Sage, very wise, and he had this quiet strength about him. He was an honorable, selfless man. He also loved deeply and fully.
Leo was a very kind man. He was always welcoming and quietly humourous.
All who knew him could count themselves fortunate. Sincere condolences to his family from mine.
I met Leo for the first time in August 2024 at our Brabant reunion in Kelowna. I know Arlette you will be heartbroken and I am thankful that your children and grandchildren will be beside you all the way during this sad passing. You are a strong woman with a strong family and I pray that he is in a better place and at peace.
My heart goes out to you and your family.
