David Lloyd Leisure Group is to be prosecuted over alleged health and safety breaches following the death of a three year old boy in one of their pools.
Rocco Wright died after being found in the pool in Moortown, Leeds, in April 2018.
Leeds City Council made the announcement on Monday after an inquest jury returned a conclusion of an accident at a hearing in Wakefield.
The hearing was told that there was only one 17 year old lifeguard on duty at the time of the incident.
Last week, Rocco's father told the jury his son's death "could and should have been prevented".
Mr Wright described how his panic grew as he searched for Rocco before he spotted him at the bottom of the main pool.
The jury found that the youngster had probably been under the 1.2m (4ft) deep water for more than two minutes.
Mr Wright explained how he was with Rocco and his daughter at the poolside and was planning to take his son swimming as his daughter had her regular lesson, but this class was cancelled.
He explained how he searched for his son before spotting him under the water, puling him to the side.
