One of the greatest advantages of being a "P.Eng." is that I can be a guarantor for a Canadian passport. I would like to retain the privilege, whether I choose to be a "Licensed Professional Engineer" or a "Professional Engineer Member".
Although I moved to Québec from Ontario 10 years ago, I have kept the PEO membership as my work place was in Ontario. Now that I work for myself in my own company, I may need to join L'Ordre des ingénieurs du Québec instead. I would like the Professional Engineers Ontario to co-operate with the Canadian Council of Professional Engineers and put priority on the membership portability and compatibility so that I can transparently switch to any other professional engineers organisation within Canada.
Also, it might make sense to issue a Certificate of Practice to companies meeting ISO 9000-series of Quality Assurance standard, without costly visits, reviews, etc.
