Adam Patrick is one of many frustrated with his experience at the Shania Twain concert at Wesley Clover Parks.

He says while “the actual concert was really good. It's disappointing that the events after the concert ruined the concert experience."

Patrick says he left the concert venue looking to take a shuttle to the Canadian Tire Centre where he parked. “We just missed the first bus. Then, there were no more busses for 20 minutes. By the time another bus came there were thousands of people all lined up on the side of the road, you know people were shoving, going in front of you." Patrick says it took him nearly two hours to get back to his vehicle.

Other complaints include one to two hour wait times for food and drink. "The lines for the concessions were probably the length of a football field,” says Patrick.

Sarah Pacey, who was also at the concert, says she was concerned about people becoming dehydrated from lack of water on site. "There were very few vendors selling water, like maybe two to four vendors for 25-thousand people."

Wesley Clover Parks has since apologized posting this message to its Facebook Page.

"On behalf of Wesley Clover Parks and our partners in the delivery of the Shania Twain concert last night, we'd like to apologize for any delays, discomfort and inconveniences that occurred during the exit at the end of the night. It is of utmost importance to us that those who visit our facility have a first class experience from start to finish. We will seriously review the viability of events of that size at Wesley Clover Parks, and will only agree to host future events of that magnitude if we are assured that a far more workable plan can be deployed and effectively executed. We thank you for your patience and your feedback."
