I was at the Union Bay, B.C. course this past week and absolutely no work was underway. It is a Gil Hanse / Geoff Shackelford course with help from another fan of this site and is apparently held up pending litigation with some groups opposing the course on environmental grounds. As the real estate market in this part of the world is much better than in the US, I gather the project may have been proceeding but for the environmental protests.
The Carrick course at Predator Ridge in the BC Okanagan Valley area is still under construction and scheduled to open next summer. Most holes are finished and those that are not are close.
From this part of the world, I have no knowledge of any other new courses under construction in BC or western Washington.
There is a possibility of Ian Andrew's course, working wtih Mike Weir, adjacent to Predator Ridge, but at last word, it is still on hold.
