Thanks for taking my question Mark.

All of Canada is 888.

"In 2000, the Canadian Radio-television and Telecommunications 
Commission eliminated all Canadian provincial LATAs in favor of a single 
LATA for Canada (888). "

Yup.  LERG6 plus it needs LERG7, I think to get the horizontal & 
vertical.   LERG8 is optional for long names (which are still not unique 
across the country).

It does look like I'll have to modify the supplied perl script to:
* either generate unique per province LATA, or
* include the province in the 30 char rate center name or
* Use NPA NXX in LCA file.
