Calypso water park has been found guilty of six out of 11 safety-related charges laid after incidents on its rides in 2011 and 2012.

A sentencing hearing is expected on June 12.

Justice Julie Lauzon found Calypso not guilty on three charges related to the Pirate's Aquaplay ride, telling the court that the TSSA's interpretation of regulations regarding staffing at Aquaplay "contain too many discrepancies and ambiguities."

Lauzon then found Calpyso guilty on two charges related to the Bobsleigh ride: that staff weren't properly trained on the day of the incident and that the ride was unsafe. But Lauzon found Calypso not guilty of the third charge related to that ride.

After a short break, Lauzon found Calypso guilty of four more charges and not guilty of one charge related to the Steamer water slide.

9 charges previously withdrawn

The Technical Standards & Safety Authority laid 20 charges against the water park for alleged safety violations in 2011 and 2012, but prosecutors withdrew nine of those charges in February due to lack of evidence.

During closing arguments in March, Crown prosecutor Tom Ayres argued that Calypso water park staff were willfully blind to injuries and didn't properly document or follow up on injuries that occurred on the water slides.

Calypso's lawyer, Lawrence Greenspon, argued in his closing statements that the Crown failed to establish any trend in some of the cases, and that only a few of the incidents were actually reported to Calypso at the time.
