I have now chosen to go after CO code 200.
There are some hurdles to overcome before an application can be made.
From the document http://www.crtc.gc.ca/cisc/COMMITTE/C-docs/COCAGL02.doc
Code Applicants and Code Holders must obtain:
OperatingCompanyNumbers? (OCN), RevenueAccountingOfficeCodes? (RAO) and CommonLanguageLocationCodes? (CLLITM Codes), and comply with the requirements for the assignment and use of such codes.
Checking out http://www.telcordia.com/services/eqp_supplier/ - will fill ing above links asap.
