Even though it's not an Ontairo event (or Canadian one), it's pretty hard to pass up mentioning Canoecopia (March 9th-11th). In Madison, Wisconsin, Canoecopia is the world's largest paddlesports expo and it's only a few weeks away. This list of exhibitors and speakers is pretty lengthy!
There are special deals for lodging if you're making the trek (and if you do, don't forget to send us photos and tell us what you thought of the show!).
