R&B singer Chris Brown, whose California probation stemming from a 2009 plea to assaulting singer Rihanna was revoked last month, said on Tuesday he was denied entry into Canada for concerts in Montreal and Toronto. It is unclear where and when Brown, whose probation was revoked by a judge last month for leaving Los Angeles County without court permission, was denied entry into Canada. He has a court date on March 20 and could face jail time. Messages left with Canada’s Border Services Agency were not immediately returned, and Brown’s publicist and attorney did not immediately respond to messages seeking comment.
