Claim
On September 4, 2022, 28 people were stabbed, ten of whom were killed,
Correction

The September 4, 2022 Saskatchewan stabbings killed 11 victims and injured 17 others, not 10 killed out of 28 stabbed.

Full reasoning

Official Canadian sources give the final toll as 11 victims killed and 17 other victims injured in the James Smith Cree Nation/Weldon attacks.

  • The Parole Board of Canada states that the mass stabbings "resulted in the death of 11 victims, and injuries to 17 other victims."
  • The RCMP's official timeline likewise refers to "the 11 lives lost" and describes the investigation as involving 11 separate homicide investigations and 17 separate attempted murder investigations.

So the article's claim that 10 of the 28 people stabbed were killed is off by one on both sides of the ledger: the correct final count is 11 killed and 17 injured, not 10 killed and 18 injured.

Claim
At least 26 were injured, including 11 fatally.
Correction

The Toronto van attack did not injure 26 people. The final toll was 11 killed and 15 injured.

Full reasoning

This sentence mixes up total casualties with injuries.

Reliable reports on the case show that the final toll was 11 deaths and 15 injuries:

  • Reuters reported that Minassian was convicted of murdering 10 people and attempting to murder 16, and that one of the 16 later died from her injuries. That means the final totals became 11 killed and 15 injured.
  • The Guardian reported the same outcome from sentencing: an 11th victim died in 2021, and Minassian was then sentenced on 15 counts of attempted murder.

So it is incorrect to say 26 were injured. The number 26 refers to the total number of people killed or injured, not to injuries alone.
