Thanks for your reply.
The point is that in the Notice of Trial there is no any word about interpreter. So that's why I am worrying they just skipped my request somehow.
I called prosecutors office (my ticket is in Brockville, and I am in Toronto, so can only call them) a couple of times and left message with the question, however, they never called me back. Don't know, what to do now. Any suggestions?

Hey guys, My situation: Filing my speeding ticket, I requested an interpreter. I marked the checkbox saying "Do you need an interpreter" although the clerk in the offence court told me a couple of times not to do it. Anyway I marked that checkbox on the ticket and gave it to the clerk. 4 weeks later I received the notice of trial. However, there were nothing about interpreter in the notice. And the clerk did not give me any copies of the ticket to prove, I requested the interpreter. So I wonder, is it possible they would say I did not request interpreter on the trial? How to find out...
