Winnipeggers are set to gather at River Avenue and Osborne Street Sunday afternoon to protest fraudulent phone calls that were placed to voters in the May 2011 federal election.

The protest is one of many scheduled across the country that are calling for a public inquiry and new by-elections to be held in ridings where robocalls allegedly took place.

Those marching say thousands of voters may have been tricked by fraudulent phone calls during the federal election in May 2011, including voters in several Winnipeg ridings. The calls were placed with automated messages to voters saying their polling stations had changed. Opposition parties believe it was to stymie voter turnout.

Protestors will march from River and Osborne to MP Joyce Bateman's constituency office on Corydon Avenue March 11.
