I hear you loud and clear but there's another side to it. Some roads are very necessary, people or no people, one for resource access and removal and two all land has to have some accesses for things like fire fighting, rescues and for just keeping an eye on inventory etc. Not as elaborate as city streets granted but the infrastructure still has to be there.
If the forest fire is far from any settlement, or in a mountain, we're going to need fire helicopters either way. We do already. I'd witnessed one countain fire in a residential suburb of Victoria years ago. The only way to fight it was with fire helicopters and planes. Canada's big; there's no way we can have roads covering every area of the country. If we want to do that, then we'll need mass immigration.
If we don't want mass immigration, then let's compact the people a bit, keep the population close to the rivers so we can build water distribution systems more cheply, and beyond that we should build only those roads that are absolutely neceesary to access natural resources, and those roads ought ot be paid for though a tax on natural resources. This will make them more expensive, but at least it will no longer mask the true cost of these resources on road construction.
If you want to own your one-family house, you should clearly pay more tax to road construction, fire, police and ambulance (they'll have to travel farther out to get you) than the guy living in a town house, condo or apartment, where the road is always busy and emergency transport hasn't far to go. Why should the condo owner pay extra tax for the gas emergency services use to go to the suburbs. Let property taxes pay for that. Again, as a way to reflect real cost rather than masked cost. If the urbanites are subsidizing the suburbs, then the suburbanites thinkg erroneously that suburbs are inexpensive when in fact they're bloody expensive to maintian owing to all the roads (which could be paid for by gas tax) and travel distance for emergency services (property tax woudl be fair for that, imho). If we did that, then suburbanites woudl think twice about their large houses that we who live closer to work subidize.
Make it user pay, rather than so much income tax. The Green Party had a point there, and in that respect was even more conservative than the Conservatives! Many suburbanites support the Conservatives precisely because they know that income tax helps to subsidize suburban inefficiencies, and masks them in the process.
