The output from nad2bin is platform-specific. It's basically the
CTABLE struct followed by an array of FLP structs, written in the
platform's native format.

AFAICT, ntv1_can.dat isn't in the same format as the output from
nad2bin. It's listed separately in nad/README (from proj-4.4.5):

		Other grid shift files
	ntv1_can.dat	--- Canadian NTv1 grid shift file (NAD27-->NAD83)
