Yes, there are many variables. There's whether or not you own the land, and whether the building is a cookie-cutter type of building, or whether it's a special purpose, iconic building such as this. Obviously that factors a lot into the planning process.
It depends very much on the procurement method; for example, if it's a building that is planned, designed, and then tendered by the crown versus the crown leasing the space. So when I say “procurement method”, that factors into it.
I would say that two years would be pretty amazing. I would hazard to say that for some of the buildings I know that were built over the last 15 years or so, it's not unusual at all for the process to take between, I'd say, seven to ten years. It's not unusual.
