Thanks slodder, Andy, Andre and Mike, much appreciated.
I thought about that irony too Mike, most of the native elm in Canada was decimated by that blight too, then it went from here to England and wiped out most British elms. Elm isn't a native species in Western Canada so any trees here were planted. Dutch elm disease hasn't made it over the rockies so the few elms here are safe for now. I managed to get some boards from a city tree that was cut down. I use it for chairmaking and turned the offcuts. It's really good for chair seats because it doesn't split and it has nice wavy grain.
