Manitoba has the highest number of people behind bars who haven't been convicted of a crime.

That's according to a new report from the Canadian Civil Liberties Association and the John Howard Society.

The report says innocent people across Canada are spending time in jail because of an increasing use of pretrial custody.

In Manitoba, 66 per cent of people behind bars are waiting for their trials compared with about 55 per cent nationally.

Corey Shefman with the Manitoba Association for Rights and Liberties says the province is setting people up to fail because of its zero-tolerance policy for breaches of bail conditions.

He says, for example, that someone who is five minutes late for an appointment set out in bail conditions, can be returned to jail.
