TORONTO -- Justin Bieber is set to perform in Toronto tonight to benefit an outreach centre in his hometown of Stratford, Ont.

Proceeds from the acoustic concert at the Danforth Music Hall will go the Stratford House of Blessing, which has a food bank and services to help those in need.

The organization says Bieber's mother used its services when he was little.

The 21-year-old pop superstar has helped out the group before.

Last year, he and his grandmother donated several of his childhood items for the group to auction off on eBay.

Bieber has also donated $10,000 to the group.

Bieber has been riding high on the charts with his new album "Purpose," which includes the hits "Sorry" and "What Do You Mean."
