I think Canadians should be more concerned with radical leftist environmental groups interfering in Canada's elections.
The Elections Office has stated that their appears to be a loophole (a real loophole) that allows foreign organizations to provide unlimited funding to support political parties and individuals as long as it is earlier than 6 months ahead of the elections.
The radical US environmental Group Tides has bragged about its impact in defeating Conservative candidates via Leadnow.  The amount of interference is so bad that even the NDP is worried about this.
