For the umpteenth time I have heard a senior U.S. politician make smarmy remarks about a 'porous Canadian border' and that they 'hope our friends to the north can do a better job after this'.

This is indeed remarkable - I didn't know that the U.S. government had given over control of entry into the U.S. to the Canadian Customs agents. But I guess it must be so, since these are all U.S. Federal politicians bitching about this. If anyone would know, they would.

As I'm sure you all know, the Canadian border is like most borders of the world when it comes to exit and entry (to another country). When driving to the U.S. you drive right through the checkpoint of the country of exit (Canada) and are inspected at the country of entry (United States), by agents of that country (of entry). Our border can only be porous in OUR direction form our responsibilities there.
