From NDPer Chris Charlton:
The purpose of this enactment is to prohibit employers under the Canada Labour Code from hiring replacement workers to perform the duties of employees who are on strike or locked out.
The enactment also provides for the imposition of a fine for an offence.
I'm not dead set against banning scab labour, although in practice any government that legislated in this manner would have the business community on their case forever. And maybe the NDP has made similar proposals when they were 3rd party-ers. But as official opposition even their private members bills are going to come under great deal of scrutiny. I can just see how this one might play out in the days and weeks ahead. Think Ruby Dhalla and Bill C-428.
