Seat pitch on ALL flights to Europe with Air Canada in Executive First is between 57-60 inches. (60 inches on the A340). The seats are very good with full in-seat video. The food is good, but nothing special.
Configurations are:
A340 2-2-2
B747 2-2-2
B767 2-2-1
----------------
A330 2-2-2 As of Dec 1999!
Executive First is a very good choice compared to a business class product in the US.
