To start, I'm going to say I have a background in ISP service, with a bit of detailed knowledge on both the service and technical side of things.
I'm a little confused. Are you talking about internet speed, or bandwidth? Those are two very different things, and I'm getting the impression from article that you are mixing the terms here.
1 Gigabits per second is talking only about speed. A full 1080p HD being streamed from, say, Netflix, requires only ~5 Megabits per second. That's half a percent of your speed.
To put that in perspective, you could have 200 people, each watching a different streaming full 1080p HD quality movie off Netflix at the same time before hitting any limits on your speed capability. Sounds awesome.. but the average person isn't ever going to see that kind of usage.
The Canadian talks were about letting resellers charge for bandwidth. If that was allowed, then if someone goes over their limit, they can be charged a price per gig on overages that the reseller determines. There are legality issues with that, considering a reseller isn't really selling their own service.. so it may or may not go against fair laws on who gets the money for the bandwidth.
Most ISPs have a limit to the bandwidth you can use. Many don't advertise, especially on the low speeds end, because they'll never hit a point where it'll matter on the infrastructure anyways. Plus, the average person (as in, over 95%, an actual statistic, I'm not pulling a number out of my butt here) never reaches anywhere near anything that would put strain on the infrastructure. If your usage starts bringing down the speeds for everyone on your network, you can be you'll get a call though.
The company I have experience with has hard limits on monthly usage. This is perfectly within laws (has been in place for over a decade). The normal practice was to call someone going over those limits to find out why (usually a virus or someone using their wireless because they left it unsecured). The rare "less than 5% of users" person went over because of file-sharing. Prior to the success of Netflix, this was the main source of going over a cap.. and it was almost always related to copyright infringement. Not that the company cared (most have a strictly "hands off as much as we can" attitude about what you actually use the internet for), they just wanted to make sure their infrastructure wasn't being bogged down by this single user.
So if you hit your limit, you'd get a call to discuss. If you need to use the extra bandwidth, not a problem, time to upgrade (or sideways shift, some business packages were cheaper with more bandwidth, but slower.. some preferred this option). If you didn't do anything and kept going over the limit, you are breaking the terms of agreement and your service would be shut off until something was done.
With the potential lifting of the "charge per use" ban, this opened a lot of options. Instead of having to upgrade to service levels you don't need, a company can charge for bandwidth usage alone. So you only need enough speed to watch a movie or tv show in HD, but you can buy bandwidth to watch a whole bunch of shows in a month, basically replacing your TV with your Internet (a laudable goal, I'd like to do that myself).
Instead of having to upgrade service to get more bandwidth, or being shut off because you are constantly going over limits.
As it was put so aptly: "Why punish your most avid users of your service? Why not cater to what they want?"
Stopping the "charge for bandwidth" option means you can't sell a bandwidth package. This means it needs to be part of a completely different service, and so now people have to upgrade and pay more for something they likely don't need just to get that little bit they wanted.
In the end, you pay for service because it literally costs more to provide that service. It really does. Laying down fiber costs a butload (I can go into specifics, but it's boring).
How about a story: I recall a time when a little town in Ontario was considered for fiber (it currently uses purchased space off a microwave tower owned by a school, granting ~30 mbits TOTAL for the entire town). Planning and marketing determined that this town of 5000 people would have to ALL have EVERY service (TV, phone and internet) in order to recoup costs... in 50 years. Fiber ain't cheap.
Docsis 3.0 equipment (granting higher than 30 mbit/s combined upload/download transfer) has costs. Not only for the modem installed in your house, but also for the entire infrastructure built to provide the higher speeds, and handle the sustained data transfer these things can manage. This is far more doable for a company, and even with that.. only a handful of people actually buy the service.
Most people don't even use the 5-10 mbits download service they have. With data transfers increasing due to Video Entertainment through your internet becoming more popular, it's something that might not stay that way forever. But really? Even 4 people all watching perfect 1080p quality picture is still going to only put even a remote strain on a 20 mbit service, and that's still WELL within Docsis 2.0 speeds. People don't need speed, they need bandwidth.
Most people want an infrastructure that can handle them downloading about 4-5 hours of high quality video a day (those that want to replace their TV service, really). This means a lot more fiber lines for higher data throughput... not fiber to the home ridiculous speeds. That fiber cost on the main infrastructure needs to be paid.. so unless the government foots the bill (like I heard they did, to an extent, in Australia), the customer needs to pay more to get more service.
I honestly have no idea if I even contradicted or addressed what you said, but I hope I least shed some light on the subject at hand. If this was simply an April Fool's joke post, then *golf clap*, because you confused me into posting a dissertation apparently.
