Long before Parliament’s dissolution in 2015, the Conservatives had run so many election ads that the official 'campaign' period meant much less than it once had—the standard had been 60 days in most elections until the rationale of shorting the campaign period to 37 days led to the use of a permanent voters list in 1997.
The appointments had been published in the Canada Gazette before the election campaign began. If the appointments were as flagrant an abuse as the Liberals claimed, they ought to have raised the issue during the election campaign.
Watch for the yet-to-be-appointed parliamentary committee to recommend a referendum and for the public to vote against change because they generally opt for the devil they know. More talk and less action on electoral reform is once again in store.
