Canadian Parliament Could Fall

In Canada, it looks like Parliament might fall, and there might be a new election.  What I find interesting is that the Liberals seem to be trying to to say that various measures which, to me, look like lack of confidence measures are not really lack of confidence measures.  I think it's a little bit weird that they are doing this, but since I do not consider myself an expert on Canadian politics, perhaps I'm wrong, and maybe they are fully within their rights to be doing this.  In any case, here is the link.
