It is with great sorrow we announce the sudden passing of our beloved father, grandfather, and great-grandfather, Dennis Dunn. In 2012, Dennis was predeceased by the star of his life, his cherished wife of 54 years, Sarah “Sadie” Dunn. Dennis is lovingly remembered and already missed by his sons Wayne (Beth), Stuart (Teresa); his daughter Diane (Eric); grandchildren Kristen (Kelli), Andrew (Lindsey), Eric (Joan), Alanna, and Kiera; and great-grandsons Jacob, James, and Ethan. Dennis was predeceased by his father Andrew Dunn (Hamilton, Scotland) and mother Inez Dunn (Spokane, Washington) and brothers Andrew “Drew” and David. He was also loved and will be missed by his many nieces, nephews, and extended family. Born in Calgary, Dennis grew up in Edmonton, spending summers in Jasper where he met the love of his life, Sadie. His 37-year long career as an accountant with Imperial Oil started in Redwater and took him to Edmonton; Regina; Calgary; Irvine, California; Al Jubail, Saudi Arabia; and Sale, Australia before retiring in Calgary. Upon retiring as a project executive, Dennis joined the Esso Annuitant Club and enjoyed a wide range of activities including hiking, bowling, curling, wine tasting, and bridge. Dennis also loved fishing, kayaking, camping, golfing, dancing, skiing, traveling, and spending time with family and friends. These adventures provided the background for his many wonderful stories. Dennis will be greatly missed by his friends and neighbours. Our heartfelt thanks to the compassionate staff of the Intensive Care Unit at Foothills Hospital.

Our deepest sympathy is extended to all the family of Dennis & Sadie. We had the very great pleasure of meeting them in Sale while Dennis was on assignment to Esso Australia. Our camping and fishing trips along with evenings of cards and stock-ticker have never been forgotten by us and never will. A truly happy, vibrant couple and a wonderful mentor Dennis was to all us young Exxon employees. Sadly missed but always in our hearts...

Dear Wayne, Stuart, and Diane,

I was so very sorry to hear of the passing of Uncle Dennis, and my sincere condolences go out to you and your families. I will always remember the many, many stories he told about he and Aunt Sadie's travels, the countries they lived, and spectacular hikes they went on. He was an adventurous, intelligent, and humoreous man that will be sorely missed by all family and his many friends.

Please take care.

Dennis and Sadie were friends of myself and Con for over 65 years. They were both special people. Together we had so many fun times including going to each others wedding, the Annuitant Club and traveling the World. I will certainly miss Dennis doing my taxes and just being my close friend. Peace of the Lord!

Dear Wayne, Stuart and Diane,
My sincere condolences to you and your family.
I only met Dennis 8 years ago when I first retired and joined the Esso Annuitants Club. I have hiked with Dennis, and was in the same casual Monday morning walking group as him. Dennis was such a fun person to walk along side of. He always had stories, jokes or songs to share with you. I have a lot of great memories and photos of those times, that I love to look at. Dennis was so kind, caring, humorous, interesting, positive and just fun to be around.
I know a lot of people will miss him tremendously, especially you, his family!
Thinking of you,

We were very fortunate to have met Dennis during our Turney Christmas progressive gatherings and at The Redmond~Van Rees' Christmas Day drop in. Such a lovely man with a genuine passion for life and adventure. Thinking of you Diane, Eric, and family at this very sad and challenging time. Big hugs to all !

So sorry for your loss. Frank and I were great friends of Dennis and Sadie. We have wonderful memories of get togethers with the Imperial Oil crew in Edmonton and Calgary, and of visiting Dennis and Sadie in Australia. Dennis was the life of the party, and a wonderful storyteller. We kept in touch, and Dennis continued emailing jokes for our amusement right to the end. Unfortunately Frank (Francis) passed in November 2019 otherwise he definitely would have posted an amusing anecdote that highlighted the "mad men" nature of the era we all enjoyed together.
