OTTAWA — The Supreme Court of Canada has restored a woman’s conviction for attempting to kill her mother by injecting her with insulin.

In June 2019, a neighbour found the woman — identified only as B.F. due to a publication ban — her mother and B.F.’s 19-month-old daughter unconscious in their home.

Emergency responders discovered five empty insulin pens at the scene, along with a handwritten note.

A jury found B.F. guilty of attempting to murder her mother and daughter.

The Ontario Court of Appeal allowed B.F.’s appeal on the attempted murder of her mother and ordered a new trial on the charge.

The Court of Appeal dismissed B.F.’s challenge of her conviction for attempting to kill her child — a decision upheld in the Supreme Court ruling today.
