Proposals like this can win votes from law-enforcement circles. After all, warrantless disclosures and always-ready surveillance equipment would allow cops to gain information about a person with just one phone call. They hate having to follow procedure, especially if that procedure involves waiting for a judge to issue an order.
There's also the more dramatic explanation about how this all boils down to a power struggle between the haves and the have-nots, but I prefer the making-cops-happier explanation. There are plenty of good cops in every country, but law enforcement has a lot of solidarity built into its ranks, so police-related groups can sway many votes. Harper would do anything for a few thousand extra votes.
It's also an issue of costs. If the government can hold up device/protocol X and say your equipment must interact with X, then it makes legal surveillance cheaper.
