A mutual recognition agreement (MRA) exists between US ABET and Engineers Canada. However, every provincial engineering association in Canada has its own interpretations of the MRA known as the Washington Accord. PEO usually assigns Technical Exams to all degrees regardless of whether it is an ABET or any other degree. PEO is more interested in making money out of it than being a regulatory body. It's managers, many of whom are engineering graduates from countries (other than US or others covered under MRA) are people who had to go through a *grind* to become P.Eng. certified. They appear to have developed an inherent acidic bitterness and discriminatory and biased approach towards US ABET graduates. Not successful in venting out their frustrations towards CEAB graduates, they are quite successful in harassing and intimidating ABET graduates. (Reverse discrimination!)
If you have not already applied to PEO, my advice to you would be to research all other provincial associations (especially Engineers Nova Scotia and APEGS) as they are more open towards accepting ABET graduates and their fees are much less. Once you get a P.Eng. in any province, you would be eligible to obtain a P.Eng. anywhere in Canada, except Quebec.
I hope this helps. PEO is an organization of scoundrels and crooks. If you have already not applied to PEO, please do not.
