Earplugs - Podfitkit
I found this mentioned on a gadget blog, it's a kit that lets you mold your own custom covers for your ipod headphones so they fit your ears better. It strikes me that the kit could be used to make a set of custom earplugs just as easily as a set of headphone covers.
For the price it's worth experimenting, anyway. I happened to have some $$$ in my paypal account, so i've ordered a set. They come USPS, so it should be pretty cheap to get them into Canada.
Posing with conviction
Another idea which has appeared elsewhere on the forum is to use the Shure E-2 earbuds that lay flat in the ear and provide really good isolation from wind noise. Both Tony and I use them. Sound quality is awesome and they are efficent so you don't have to crank up the volume to hear the tunes. And to Tony's suggestion, use a Lululemon skull cap to keep the earbuds in place and to keep your helmet clean.
