Sections 109 and 118 will be excellent options for the July 13th Queen and Adam Lambert concert given that the Air Canada Centre will be configured in the End Stage West setup. The front of the stage will be closely aligned with the left aisle of section 109 and the right aisle of section 118. The closest seats will not be behind the stage, and it is hard to find a bad view from these sections.

Sections 109, 118
Sections 109 and 118 are some of the best options for end-stage concerts at the Air Canada Centre

If you want a better angle to the center of the stage, look for lower numbered seats in section 109 and higher numbered seats in section 118 for more distance from the front and a better viewing angle.
