Let me add this:

From the EAA: "The US and Canada have agreed not to require US or
Canadian pilots to have a restricted radio-telephone license or an
Aircraft Radio Station License."

That's from:

From AOPA: The AOPA/COPA Guide to Cross-Border Operations (United
States/Canada) - Arrival Requirements:

http://www.aopa.org/members/files/tr...ada/can02.html

"Aircraft Documentation

"Aircraft registration certificate (temporary "pink slip" registration
forms are not valid for international flights);
Aircraft airworthiness certificate (for aircraft with a C of A);
Aircraft operating limitations (including the "Standardized Validation
of a Special Airworthiness Certificate - Experimental, for the Purpose
of Operating a United States-Registered Amateur-Built Aircraft in
Canadian Airspace);
Weight and balance information;
FAA 337 form when the aircraft has been fitted with extra fuel tanks
in the baggage or passenger compartments."

"Licenses and Certificates

"Just because you are allowed to fly an aircraft in one country does
not mean that you can fly that same aircraft in another country!

"Licenses that meet ICAO standards, including all Private Pilot,
Commercial Pilot and Airline Transport Pilot Licenses (Canada) and
Certificates (U.S.) are valid to fly your aircraft on either side of
the border.

"Other permits and licenses are not necessarily valid on the other
side of the border. For example the Canadian Pilot Permit —
Recreational Aeroplanes is only valid when flying a Canadian
ultralight in the U.S. under the blanket authority document. The Pilot
Permit — Ultralight Aeroplanes is not valid for flying in the U.S.,
unless you are flying a Canadian Ultralight and have an instructor
rating and two hours of cross country time, as required in the blanket
authority. Likewise U.S. Recreational Pilot Certificates are not valid
in Canada. Student Pilot Permits are not valid outside the issuing
country."

Nothing about an FCC license. Note that COPA is a party to the
document.
