Crews are responding to a small wildfire discovered south of Spences Bridge, B.C., on Canada Day. One witness told CTV News she saw white smoke billowing from outside the community – located between Lytton and Merritt along the Trans-Canada Highway – around 2:15 p.m. Few other details have been confirmed, but the B.C. Wildfire Service said the fire is suspected to be human-caused. Hours after the fire was discovered, the BCWS said it remained less than a hectare in size – and officials are not anticipating much spread.
