One more bit of data: on page 68 of "The Fabulous Firebird", it states that in 1967 Firebirds were produced only in Lordstown. In 1968, production continued there but also started up in Van Nuys. And in 1969, the Norwood plant joined the other two. For 1970-71, Lordstown stopped making Firebirds, then Van Nuys stopped in '72, leaving only Norwood for the next six years.
No Canadian plants building First gen Firebirds - or second or third for that matter. More confirmation from the time of the myth. The answer was there all the time.
