As far as I know NVG are still being investigated. The RCMP are training (maybe flying) with them. I've heard rumours of Air Ambulance wanting them. I'm just not 'in the know'.
I'm in the military and we use NVG for these types of missions. The one above was when the use of NVG was in its infancy. We were still restricted to unaided flight for hoisting and landing. Also, we could not have mixed cockpits. When we did the hoist the second time I wasn't flying, so I ended up putting on my goggles, just so I could see that terrain I mentioned. At the time, that was against the rules, now we can use judgement in situations like that.
