How will legislation work? Can it be legal today and illegal tomorrow, a period of transition is needed, grandfathering existing stocks of restaurants and seafood produces shop? Economic compensation if confiscation of shark fin from current owners? Enforceable?
All valid points. My understanding is that most of the market is controlled my criminal cartels. In many cases, the sharks are being caught illegally in protected areas. There was another ship "arrested" in the Galapagos just a couple of weeks ago.
But you're right, there probably needs to be a phased-in approach.
I tend to travel to Central America a lot on business and on a similar note, many of the poorer areas (say Honduras for example) have a major problem with illegal fishing. Much of this isn't done on a large scale... it's some guy in a boat with a line, catching a few grouper to sell to a tourist restaurant so he can feed his family. If you think the current economic situation is tough here, you should see it in Honduras. My point is that many of these sharks are caught by local fisherman who aren't "evil" people. Just guys trying to make a living. All the same, wiping these animals into extinction doesn't do anyone any good, other than the companies/organizations that control the markets. The dude doing the fishing is scraping by. The thugs that control the industry are getting rich.
Banning the sale will not stop shark-finning, but it will reduce the market for it, and eventually, it might not be worth it. It will also have the side effect of making criminals out of resauranteurs who insist on serving it anyway. Such is life though.
"Fishing" generally is a destructive activity (I don't mean those of us that enjoy landing a smallie once in a while). Commercial fishing is totally non-selective for the most part. A dragger pulls up everything in it's path. The non-commercial species are simply discarded, dead. What a waste. Shrimp fishing can create 100s of pounds of dead by-catch for a handful of shrimp...
You might not be aware that California, which is the largest market for fins outside of Asia, has now banned the importing or selling of shark fins. Shark-finning in US waters has been illegal for "ever" I believe. So it isn't like Toronto is leading the way with this legislation. There will be many examples of other jurisdictions' bans that can be copied.

Simon, your point about the waste is bang on and driven only by money. The fins are valuable. The rest of the shark isn't, so it's dumped.
This isn't really a fair comparison, since cattle aren't exactly endangered, but can you imagine the public uproar if meat processors took a steer, hacked off its back legs because that's where the best beef comes from, while it was still alive, and then dragged the bleeding, maimed animal back out into a field to bleed to death. Imagine driving through the country and seeing thousands of cattle bleeding, dieing a terrible death. Shark finning is no different. We just don't see it because it happens far offshore and the animals sink out of sight. The fact that many species of sharks are nearing extinction makes it that much worse.
