Dear Slater family,

I am terribly sorry to learn of your loss and of Peter's death. I met him while a student at Trinity College in the Faculty of Divinity, and always experienced him to be supportive. After graduating, I would encounter Peter at least once a year at academic conferences, and was always struck by his undying enthusiasm for academic conversation.

I very much regret being unable to attend the funeral, due to hosting the Primate at Trinity at the same time. Please be assured of my prayers and best wishes at this time of mourning and of celebrating Peter's life.

I was sorry to read of Peter’s passing. We had not been in touch for years. His father Bob and my mother Margaret Durley were married for a few years in Georgeville QC. We saw each other there from time to time. One of my daughters, Alexandra, reminded me today that your father took her and her sister Heather out sailing one day on his catamaran on Lake Memphramagog.
My mother was fond of Peter and I recall at her and Bob’s wedding reception he wondered if my mother knew what she was taking on!
My sympathies to your whole family.

I have many fond memories of Peter and Nan at the cottage and one that stands out vividly is from when I would have been around 7 years old, eating blueberry eggo waffles at the breakfast table, with Peter flipping through the paper with one hand and the other petting the head of one of their dogs. I don’t know why this memory has stayed with me so long. I hope Peter is resting as peacefully as that moment was ◡̈
