Gearing up for side work

Since I work 1 week on 1 week off wrenching I'm looking at getting some small side jobs on my time off. I'm looking to do it legitimately (ie no cash under the table).

So aside from registering a company, what will I need to do? Insurance seems like a smart idea. What about WCB? Will I need to pay into that as well even though I plan on being the only employee?

I'll likely be based out of Alberta but may try and pick up some work out of the province as well.
