I have very fond memories of Fr. Lonc. We spent many hours in the lab in Mc. Nally discussing the Calculus. He'd go only so far with the problem and leave the rest "for the secretary" to complete. Then he would leave for lunch. He gave me keys to the roof and to the Amateur Radio station VE1SMU where many interesting HAM contacts were made using modest equipment. Fr. Lonc, you were an inspiration to many who had the honor of interacting with you... Godspeed.

Fr. Lonc assisted me greatly during my early struggles as a new International Student to Canada. I have known him since 1983 and we always kept in touch until Spring 2014. When I didn't receive a Christmas card from him this Christmas, I knew that something was wrong.
I will always remember Fr. Lonc and be grateful for the sacrifices he made. Please God take good care of him!!

I took a few courses from Father Lonc in 1988-90 at SMU yet my memories of him are not from the classroom but from the many times I would see him come and go on an old bicycle, seemingly quite happy with himself. He passed away just 3 weeks ago and I "accidentally" discovered this news after all these years.

I am originally from Halifax and I have fond memories of Fr. Lonc. He was a wonderful man. I was introduced to him in high school (Grade 11 in 1998) by my math teacher a former student of his way back when he first started teaching at Saint Mary's. In high school, I helped him scan important documents related to his translation work on the early Jesuit Missions in New France. That was almost 15 to 16 years ago now and we kept in touch all through high school, university, his retirement, my marriage, and brief illness leading to his death.

Fr. Lonc was a wonderful mentor and teacher, he always had time to listen and counsel. He even helped edit my own book that I later wrote. He will be greatly missed by both me and my twin brother Jerrice who he also got to know. I specifically remember Fr. Lonc attended the funeral of a close relative of mine in show of his support. He was an amazing man.

May the Lord bless his soul and he rest in peace,

Hearing this news of Fr. Lonc greatly saddens me. Fr. Lonc provided such encouragement and mentorship to me over the years-- when I was his Physics student and research assistant at SMU back in 1981-1985, and also over the years since then when I would return to the basement office to visit and enjoy wonderful lunch conversations with him at House of Ma. What a treasured relationship we had over many years. My only regret is not having contacted him recently, though I have thought of him many, many times. I will always remember and pray for him, with great respect, admiration, and love.

Fr. Bill and I worked on his Early Jesuit Missions to Canada series that comprised of over 65 volumes. He did this work in a short span of 15 years. He finished a book two months before his death, and I know he still had other projects planned. He was a gentle man, a brilliant physicist and historian, and a good priest. I consider myself blessed that he called me "friend".

Father Lonc and I transcribed and translated a dozen books together about the 19th century Jesuit missions on the great lakes. We had hoped to do more. I will miss his intelligence and humour. Shelley Pearen.'

Father Lonc was my BSc. thesis supervisor in 1988. I enjoyed sharing his interests in astronomy and physics, as well as tinkering with various science experiments. He kindly invited me to a trip to Sable Island to help with maintenance of some microwave transmission equipment, a trip I greatly enjoyed. I valued his humour and will miss our (far too infrequent) communications.

Ksiadz Lonc was a very welcome guest in my parents home among their circle of Polish friends.
He kindly officiated at several of our life ceremonies including my Dad's funeral in 2001.
We are grateful for having known this exceptional man.
