Tank bag - have a look at the icon primer pack. I had to give mine away to my gf who uses it on her bike. Ebay replacement cost less than gpbikes.
+1 for the rear cargo net, but lots of use will scratch up your pain.
A waterproof canoe bag for overnight trips with some bungee cords.
Frame sliders/crash guards - don't cheap out, do your research here.
Earplugs, winter gloves and battery tender jr (ebay is cheapest), front and rear stands (Royal distributing has a great set)
Visor cleaner and rag for buggy rides. Keep it in your tank bag.
Tire pressure gauge for your tank bag or toolkit.
Front disc lock for a visible deterrent while parked, and for touring.
Tinted visor unless you prefer sunglasses.
Chain lube, chain cleaner or simply kerosene and a paint brush with some rags. Cut the paint brush bristles halfway down and you have a one of a kind stiff bristle brush that is o-ring safe for 3 bucks. Kerosene is sold at crappy tire in the camping section.
A set of metric allen key sockets from lowes, home depot, Canadian tire.
Blue loctite for any fastener you remove and replace.
Source your oil and filters, you'll need an oil pan, filter wrench, probably a 17mm socket and wrench. Get a few filters, chances are you'll need two oil changes this year.
Rain gear, this is canada after all.
Think about Rok straps, they'll hold your raingear and are much kinder to fairings than bungee cords.
Maps, gps, or a cellphone.
Great ontario bike roads. A google search will find a large jpeg on this site. Great resource to find the best roads for motorcyclists in the province.
Sticker remover. Do some research, everyone has asked "how do I" on this site.
A couple of books and dvds on how to take it to the next level.
Proficient motorcycling
A Twist of the Wrist II dvd
Sport riding techniques
(The last two are the best for sport bikes)
Congratulations and ride safely!
