Of course this can happen here, and there's no reason it shouldn't.

First, the article doesn't say that they are searching homes, only that they are knocking on doors and asking whether there is a gun in the house. That doesn't violate the constitution at all, and at least in this country the homeowners would be free to refuse to respond.

Second, were this going on here, police might have "probable cause" to search because they are visiting people who, it appears, purchased guns but never registered them, or let the registration lapse. It appears that this is illegal under Canadian law; thus, there is sufficient evidence of a possible crime.

Third, all of you gun lovers argue against new gun control laws with the mantra, "If we just enforce the laws we have ..." And yet, when there is enforcement, which is exactly what this is in Canada, you're all up in arms (pun intended). Not to mention whining and excuses ... "the paperwork is too hard," "how could they know it was a straw buyer" (re: the gun shop that was closed down).

If the law requires guns to be registered, and the police have reason to believe that a home contains unregistered guns, then I'm all for enforcing the law, which is exactly what's happening here. (Although, actually, they aren't even enforcing the law; they're offering amnesty).
