We were so sorry to hear of the passing of Dan. I will always remember him sitting out front of your house in Brampton with his cheerful disposition when I came by to pick Jonathan up. He would have a quick joke and a great smile. I am glad he is at peace now after all his health struggles. Our thoughts and prayers are with all of you.
Much love from Robert, Jocelyn, Jonathan Dunn and Meghan Mendelin
Will miss you Dan, especially your dancing. Keep well Geraldine.
Dear Geraldine
You and the family are in our thoughts and prayers.
Dan was a lovely person and a true gentleman. He will be missed.
Very sorry to hear from Lisa of Dan passing ! He was a very nice person and I will alway rember him as a great dancer! Love Denis Linda and Martin family ❤️🙏
I had the privilege of working with Dan for quite a few years at Almag. He was a kind man & I learned a lot from him on our processes as well as how to tell it like it is. He was a highlight at our Christmas parties, burning up the dance floor. My thoughts are with you all, Connie
Very sorry for your loss. My condolences to all his family. I worked with Dan for many years at Almag and we shared a lot of good laughs and stories. Dan was a very kindhearted and always had a smile for everyone. RIP Dan
