"Words cannot express my shock and sorrow at the horrific events today in La Loche," Premier Wall said in a statement. "My thoughts and prayers are with all the victims, their families and friends and all the people of the community."

The La Loche shooting is said to be the deadliest school shooting in Canada in the past 26 years. Back in 1989, a 25-year-old man opened fire at École Polytechnique in Montreal, killing 14 people and injuring 14 others, mostly female students. He then committed suicide.
