The past president of the Bramalea Celtic Club in Brampton, his wife and their granddaughter were victims of a deadly garbage truck mishap in Glasgow Monday.

Jack Sweeney, his wife Lorraine and their granddaughter Erin McQuade lost their lives when the truck veered out of control near George Square, a busy downtown location, and hit several pedestrians.

In all, six people were killed in the incident and at least ten people, including the driver, were seriously injured.

Members of the Bramalea Celtic Club expressed their condolences on the group’s Facebook page.

“It is with great shock and sadness we share with you our friend and past President Jack Sweeney, his wife Lorraine and granddaughter Erin were victims of today’s tragedy in Glasgow,” reads a post from the group. “Our thoughts and prayers go to the family and friends of the Sweeney family.”

Thomas Donnelly, a close friend of Sweeney’s, said Sweeney was president of the club from 1996 to 1998.

“Jack was a really quiet man; Small guy in stature, big heart,” Donnelly told CP24 Tuesday morning. “Both of them were very nice persons. Beautiful people.”

Sweeney loved children, Donnelly said, and was big on donating proceeds from the club’s activities to charities that helped sick children.

The couple used to live in Scarborough and drove to the Brampton club every weekend, even though they did not like driving in the snow, Donnelly said. They returned to Glasgow in 1999 because Sweeney missed Scotland and his family there.

Donnelly said the couple was very well-liked and he is getting calls from people all over North America who knew them.

Erin McQuade was an employee at the Cameron House Hotel and Resort in Loch Lomond. The resort issued a written statement to extend condolences to McQuade's loved ones.

"Cameron House Hotel and Resort are saddened to hear we have lost one of our brightest and dedicated members of housekeeping staff, Erin McQuade," the statement read. "We want to offer our deepest condolences and sympathies to the family of Erin and to all those who have been affected by the tragic events at George Square yesterday."

No charges have been laid yet in the crash, but police are still investigating. Superintendent Stewart Carle of Police Scotland said the incident appears to be “a road traffic accident, nothing more sinister.”
