Background
The Matte service station was located on what was then Ontario Highway 69 (now Municipal Road 80) in the Town of Hanmer (now part of Greater Sudbury) southeast of the intersection with Desmarais Road, in an area called Ross' Corners or Gauthier's Corners. The station was owned and operated by Earle Matte, and the attached lunch counter was operated by Earle's wife, Delilah. The lunch counter was described as being a popular meeting place for adults and teenagers in the area.
Explosion
In the afternoon of August 1, 1963, Shell Canada fuel truck driver Edward Thorpe arrived at the service station to deliver gasoline. While the truck filled the underground tanks by gravity flow, Thorpe went into the restaurant to have a pop. A customer entered and reported that the truck was overfilling the gas tanks, and it was discovered that gasoline was running on the ground and spilling into the basement of the service station. Thorpe stopped the gas flow, and went into the basement to assist with cleaning up the gasoline. The gasoline, estimated to be around 400 impgal L, was hosed down into a sump pit by Thorpe and two teenagers, Rene Menard and John Ross.
After all three left the basement, the sump pump was switched on by the filling of the pit, and the fuel was ignited by the spark of the switch.1963-08-03 Gas Overflow, Spark Caused Blast in Garage https://books.google.com/books?id=5l5jAAAAIBAJ&dq=explosion+sudbury&pg=PA1&article_id=4170%2C311247 The StarPhoenix 1 The explosion occurred at 4:17pm and immediately destroyed the service station, lifting the building off of its foundation.

Casualties
Seven of the victims were killed instantly in the explosion, with an eighth victim, 14 year old Linda Duguay, dying later that day in hospital. Earle Matte, the owner of the service station, was not present when the explosion occurred. His wife, Delilah Matte, who operated the lunch counter, and their 4-year-old daughter Norma were killed. Delilahs sister, Estelle, her 17 month old son Vincent, and their mother Alma D'Amour, were also killed, as well as 15 year old Jo-Anne Marois and 15 year old Raymond Genereux, who had started working at the station 2 days prior.Mulligan Carol 2013-07-27 Accent: Hanmer residents are still haunted by deadly explosion that rocked their community 50 years ago https://www.thesudburystar.com/2013/07/27/hanmer-residents-are-still-haunted-by-deadly-explosion-that-rocked-their-community-50-years-ago 2025-10-04 The Sudbury StarKeown Mary Katherine 2013-08-06 Families of the victims mark the 50th anniversary of the Val Therese explosion https://www.thesudburystar.com/2013/08/06/families-of-the-victims-mark-the-50th-anniversary-of-the-val-therese-explosion 2025-10-04 The Sudbury Star A further 6 people were injured, but survived.
Aftermath
At a coroner's jury on August 12, a jury found "a degree of negligence" by Edward Thorpe and Shell Canada. It was determined that the amount of gas in the underground tank was not measured beforehand, and that Shell Canada did not provide sufficient training requiring their drivers to stay with their trucks during the filling of tanks. Thorpe was also praised for quickly moving the truck away from the destroyed service station, which prevented another explosion.1963-09-13 Negligent Driver Also Praised https://books.google.com/books?id=3GBkAAAAIBAJ&dq=hanmer&pg=PA3&article_id=5863%2C2683187 Calgary Herald 3
