An autopsy has revealed there is nothing suspicious about the death of a two-year-old boy found unconscious inside a downtown Toronto home Monday morning.

The post-mortem exam, which concluded Tuesday, found that the child’s blood samples had traces of the flu, Toronto police Insp. Gary Meissner told CP24.

Meissner says more testing on the blood is required before it can be determined if the flu was the cause of death.

The toddler was found without vital signs by his father inside their home on Ontario Street shortly after 9 a.m. The father promptly called police.

Earlier, a spokeswoman for Toronto Emergency Medical Services said another child at the home was taken to hospital with a non-life-threatening medical condition.

Kim McKinnon said the boy, who is about five years old, had flu-like symptoms, but his condition was not serious.
