Two small explosions were deliberately set during the thick of Canada Day celebrations at Lheidli T'enneh Memorial Park.
About a dozen police responded, as did a contingent of firefighters, during late afternoon festivities.
The loud bangs at about 3:50 p.m. startled the crowds nearest the incident at the southwest side of the park. Many others in the park heard nothing and carried on their revelry.
"We have established a perimeter and we have called in a dog unit to help the investigation, just to be sure," said one Mountie on-site. "There were no injuries caused that we know of."
The damage seemed to have been limited to a garbage can, where the first and loudest of the pops occurred. A second smaller bang came immediately after the first from the roof area of a small building near the garbage can.
The police did not characterize the blasts as bombs, rather the work of vandals thoughtless to the disruption they would cause the public or the potential harm it might cause.
This turned out to be minimal.
"People weren't worried," said one mom passing by with her two young children. "The bangs weren't very loud, and nothing happened after they went off. Some people actually ran up to the garbage can and looked inside before the police could get here to rope it all off. Then everyone just carried on doing what they were doing."
A large police and firefighter presence was in the park already when the explosions happened, so response time was swift. Many of these personnel remained in the park long after the event was put to rest, to carry on watching over the public.
