This article says that the canard and main wing on a Velocity use the same airfoil section. I didn't realize that. Is it true?

Honestly, I'm not sure anybody really knows. Danny Maher didn't really use official airfoil shapes, and haven't seen any documentation that the situation changed even with the 173/long wing or XL. In fact, I was told by EAM when I bought my model, that when they wanted to build their RC version of the Velocity they took measurements off a flying airplane because the existing drawings and plans were not sufficient to model from.

The best, definitive, information I've ever found was in this Sport Aviation article from 1986 (you have to be a member to download it-relevant quote is below).

The outer wing panels have a modified Long-EZ airfoil, but the inboard strakes have my own airfoil. I developed my own airfoil for the canard, also, and the elevator is 38% of the canard's chord. I used John Roncz's vortilons on the wing simply because of all the good reports I got from Long-EZ builders who had installed them. I figured if they were as good as everyone says, I might as well use them.

Now if I only had $250,000! Gotta admit, it's a pretty compelling alternative to a lot of similarly priced used and new twins out there; if you've got the time and space to build.
