NEED TICKETS TO FEB 13th SHOW

I've been trying to find tickets for Michaels show at Niagara Falls for my mother. I grew up listening to his music all thanks to my mother. She is a major fan and would be so grateful just to see him. She has seen him in concert for the passed 2 years, this would be the first year that she wouldn't be seeing him. This year was a tough year and I think this would cheer her up. She plays his music all the time, and I've adopted her love for his music. We sing his songs all the time. I've never seen him in concert. So this would be a great experience. I've been trying to find tickets for a while now and haven't had any luck! :(
