Ian,
As you know, I'm yet to see any of Park's historically significant work in Quebec, unfortunately. Islesmere sounds like it's worth the trip. (I think you had told me that before... I must have had a few too many Labatt at that point in the conversation last time!)
Ottawa Hunt and Toronto Hunt are a disaster, two historic courses in Canada that would have been much better served in the long run retaining their history. Ottawa Hunt is definitely a eye-opening study - much like Inverness in Toldeo - on "modernization". Yet, if go to Tom McBroom's website, you can read about how he respected Willie Park, Jr.'s original design and restored the course to Park's original intent. What a joke.
Royal Ottawa has a ton of potential. But, as far as I know, it's Tom Bendelow's work originally. Perhaps Park visited and did some remodeling work later? I'm not sure.
Nonetheless, Cooke's work over past decade or so at Royal Ottawa (I think he's been working with the club that long) is very "modern" in appearance. And far from comprehensive.
I visited a few years ago and was astonished at how much the original green parameters had shrunken in over the years. None of them had been expanded back out to their original margins. Many evergreen trees have been planted as well, and as a result, the course is very, very claustrophobic.
Moreover, a bunch of new bunkers and several new greens contrast greatly with original features.
It's quite disappointing, 'cause I think Royal Ottawa has tremendous potential to capitalize on its history. It's kind of a Canadian version of Myopia Hunt, Garden City, old Inverness... that vein. If some of those classic features were reinstituted, along with a classic aestheic, Royal Ottawa would become again one of Canada's most unique golf courses, complimenting by one of golf's most attractive, and historic clubhouse overlooking the 18th green.
I fear though, we have another Ottawa Hunt on our hands.
