All,

There is an L33 in Ottawa.
I know I'll need an export certificate of airworthiness. I know I'll need an annual. I know I'll need to get an N-number. I know I'll need to get the FAA or a DAR for an airworthiness certificate.

Yes, you probably need an Export C of A.
What is actually required depends on your regional FSDO.
A few years ago, some of us bought a Lark from Montreal.
The seller said, "No, you don't really need an export C of A. We've sold several into New York without one."

But we were under the wing of the MPLS FSDO. They had not played this game before. Without the Export C of A, the glider had to be disassembled and reassembled under the watchful intermittent eye of the FSDO inspectors. After about 6 weeks, 5 folks from the FSDO traveled almost 100 miles to watch our guy demonstrate that all the control surfaces had exactly the prescribed range of motion, and other minute details. The glider was purchased in May and finally flew in September, if my memory serves.

As we all know, each FSDO is its own fiefdom, and we're better off, in general dotting the Is and crossing the Ts.
