With respect to the 407 a couple of factoids (if I remember correctly)....
1. The government still owns the 407, they just sold the rights to operate the thing for 100 years to the Spanish.
2. The sale of the 407 was an international tender with the sale to the highest bidder. Anyone, even you, could have bought the thing.
3. The successful bidder paid more for it than anyone else ON THE PLANET.
4. The purpose of the sale was so that the missing pieces (the gap in Mississauga to Oakville, the eastward extension from Highway 48, the new 412 to the 401, the new eastward extension again etc.) would be designed and constructed by the successful bidder. The tax payers of Ontario did not pay for that work, the consortium who bought the rights to the 407 has.
5. In about 80 years, the entire thing reverts back to the province of Ontario (if Ontario still exists at that time).
6. The province of Ontario gets a cut of the revenue.
1.) The 407 was leased for 99 years and reverts back to the Ontario Government around 2096. Maybe drones will be the form of transport and the 407 will be a dinosaur by then, requiring the Government to reshape the infrastructure / highway. Especially as it costed the Government $104 billion to purchase and construct it in the first place.
2 & 3.) For sure the deal was too much of a sweetheart deal at around $3.6 billions with no stipulations as to the charges to customers and the amount that they can raise the rates. They have increased the charges every single year. That is why it has gone up by over 1000% compared to day 1 of the charges kicking in, making it the most expensive highway on the planet. Compare the amount the Hydro rates have increased by since 1996, and there is no comparison.
4.) Not true as the Ontario Government completed the extension of the 401 to the 412 and further Eastwards to Oshawa. That is why the Province owns this part of the extension and the rates are significantly cheaper than the 407ETR. The 407ETR collects all the tolls and forwards the Province it's share of the 407East, minus their costs to collect those tolls. So let's get that fact right.
5.) Yes it reverts back in 2096. But imagine the amount of profits that the 407ETR has managed to make. All because of the stupid let's balance the books by the Harris Government and sell the hen that lays the golden eggs.
6.) Again the only revenue that the Province gets back is for the 407 East as explained above.
