The news seem to have been circulating for a few days now. It is however still not confirmed at this point.
We have received some messages from fans indicating that Roxette are to play at Molson Amphitheatre in Toronto on August 30, 2012. But again, as mentioned above, the date is still not confirmed and the information we could find was published on ticket reseller websites.
We will post the official information and the link to the official ticket seller when we receive it from Live Nation. For now we can only recommend to wait a little bit and avoid super expensive reseller websites.
