The Conservatives did not share a reason for why they dropped Singh, merely confirming that he was dropped as a candidate in a one-line email to CBC News.
I get that they don't want to provide fodder for the media in case there's something particularly egregious about this guy; but their unwillingness to engage with the media is shaping up to be a troubling pattern. If they're unwilling to be open and transparent now, why would anything change if elected?
