In my husband's case he came here in Toronto when he was only 14 yrs old. He attended secondary, Seneca College and Ryerson University here in Ontario Canada. He studied Computer Programming and working at Bell Media. When he applied for Citizenship he still went thru on the same processed like most of us here. I think if anyone entered here in Canada as a Landed Immigrant, FSW, TSW etc. As long as we're not a NATURALIZED Canadian we still have to provide a English Proof in the citizenship application.
I also knew someone before and applied for citizenship. She has Masters Degree and her occupation was Judge in Iran. She also studied here upgrading her skills. The other one was a Bachelors Degree she was a English Teacher abroad. She also studied here and got a recognition. Both of them included their English Language proof.
I think English Langauge proof is mandatory to all non-naturalized Canadian when applying for Citizenship. No matter what degree we have had in our home country. In addition, we have nothing to lose if we sends our English proof. Because at the end of the day, despite of all the circumstances we're still the one who'll benefit from it.
