It reminds me a bit of Bruce Schneier's Movie-Plot Threat Contest that has fun at the expense of misplaced fears and useless security measures. What's the point in wasting millions of dollars to combat a theoretical problem? In practice very few women wear veils. Even if this problem does exist it's too statistically insignificant to affect the outcome of our elections, and thus probably a waste of resources.
A similar discussion over voter fraud by illegal immigrants is taking place in the US - though the percentage of illegal immigrants in America is, I imagine, larger than the percentage of hijab-wearers in Canada.
