Alberta Health Services has confirmed that the seven-year-old boy who was pulled from the pool on Tuesday at the city-owned O'Leary Leisure Centre has died.
A lifeguard at the north Edmonton facility found the boy lying face-down in the water around 2:30 p.m.
Lifeguards and paramedics performed CPR on the child. He was not breathing when he was rushed to hospital.
The city is launching a full review of the incident, which is expected to take 6 to 8 weeks.
"Given the seriousness of this incident, we do plan to ask [an] outside expert to participate," said Rob Smyth, branch manager of community and recreational facilities. "Having a third party come in, external eyes, for us, is very important."
Smyth said there were 82 people in the pool and two lifeguards on duty, which meets city standards.
