Pros:
I haven't played enough Canadian courses to call the Toronto (Ward) Island disc golf course, the best in Canada, or even in Ontario. But it is certainly among the most unique. No one will dispute that this course is a very special place to play disc golf.
A 10 minute ferry-ride from the mainland, the Ward Island course is separated from the big city, which gives the island(s) a genuinely placid ambiance. The view of Toronto's skyline is unparalleled, particularly at night.
The only vehicles allowed on the islands belong to the park system or Emergency services. Even those who live on the islands must get around on foot, bike, boat or skateboard, if they so choose.
The course I played in September of 2012 bears little resemblance to the 1987 PDGAW courses that put me in the disc golf spotlight for years to come. It is better. Far better. Admittedly, this place holds incredible sentimental value for me. But the quality of this venue transcends this sort of bias.
At well over 8,000 feet in length, whether or not it is listed as a "par 64", it plays like it. And due consideration should be given to par on this course. This course gives the smart player plenty to think about and puts the less-strategy-oriented players to work. Risk vs Reward is artfully engrained into the multi-shot holes. The most basic tenant in the game of golf is to reward well executed shots and punish poorly executed shots; which the Ward Island course accomplishes in spades.
The fairways are immaculately manicured. The rough areas are well-defined and often unforgiving, but I do not recall any thorns or vines.
Mach 5 baskets provide the player with a solid place to finish out each hole. There is talk of a 2nd set of permanent targets. Combined with 2 and even 3 tees per hole, that's 4 to 6 ways to play each fairway... without having to move equipment.
Benches adorn most tee areas, though mostly by the longer blue tees.
Cons:
The asphalt tee pads are usually long enough and grippy enough, but several aren't flat enough. The tees (not installed by players) go with the lay of the land, rather than lying uniformly flat, which I feel is the course's biggest short-coming. Others may barely take notice.
That said, the course topography is primarily flat. The only real elevation change of any substance is the drop-off beyond the sea-wall to the right of fairway #4 and the elevated baskets on #4 & 9. (Usually reserved only for tournaments)
A mandatory ferry ride or water taxi makes the course just inconvenient enough to keep the course from being overrun by players. The shortest walk is 10-12 minutes to tee #1. If you want something during the course of the round, you'll have to bring it on the ferry. Bikes and strollers come in handy here.
In playing the event, it seemed that some of the par 3 distances were longer than the tee signs indicated. If they are, in fact, correct, kudos may be in order for making fairly flat fairways play longer than they actually are.
There are a couple of holes that I might consider a "tweener" distance, but top-level Open Pros would likely not. The shorter tees bring many of these holes into range for a GM, like myself.
Other Thoughts:
All things considered, the Toronto-Ward Island disc golf course is a rare and beautiful gem. An "absolutely MUST PLAY" course if you love a fair challenge, a beautiful setting or if you are looking for a reason to get on a boat with a bag of discs.
