“Grieving parents who lost their nine-year-old boy last week say their son died after a severe asthma attack made worse by wildfire smoke engulfing parts of British Columbia.

Amber Vigh said her youngest son, Carter, died in the emergency room with his parents at his side at 7:20 p.m. PT last Tuesday.

“They tried everything … I just stood there and just told him that I loved him and just to breathe,” Amber said in an interview from her home near 100 Mile House, B.C., on Monday.

“This time was just different.”

Vigh’s death comes as smoke from more than 360 wildfires sends air quality across B.C. plummeting, particularly in central and northern areas of the province.

Government officials and health authorities have warned people in those areas with pre-existing conditions to be cautious, acknowledging the contaminated air can make a person sicker or hasten their death.”
