I don't think they inform you if they deny your application to vote by mail here. It's 8 days before the "we need to have your ballot in our hands" deadline for mailed votes and I still don't have anything. Guess I'm not voting? Pretty cool how they can just arbitrarily deny your ability to vote.
How did you actually do the application? Did you have to phone someone? Send an email?
Who is actually in charge of organizing the election there? Here it's the job of the City Clerk, and by this point I would be insisting VERY INSISTENTLY that this be dealt with.
They cannot legally deny you your right to vote. Is there a candidate you want to vote for? The way I handled the situation in 2015 when the <unprintable> Returning Officer pulled her "it's too inconvenient to bother sending a team over to your home" garbage was to contact the candidate I planned to vote for and he put one of his team on to help me. That person went to the Returning Officer and
told her flat-out that it was unacceptable to deny me my right to vote. In short, I found an advocate to help speak for me. I persisted, wouldn't take "no" or any other crap for an answer, and she sent a team over so I could vote.
It's a bit depressing that I may have to go through this twice next year. But actually the provincial election wasn't a problem. Once I pointed out that the other levels of government allow in-home special ballots for disabled people, they had no problem about looking up the procedure and arranging it.
The federal election has been a nightmare on two occasions. The first time I flat-out asked, "Are you trying to deny me my right to vote?" and got a mealy-mouthed answer. So I ended up calling back the next day, going over the first EC worker's head, and got the ballot arranged. The first worker ended up getting fired.
You are a Canadian citizen who is over legal age, resident in the municipality where you intend to vote, you presumably have whatever ID they require, so they cannot deny you.
Be persistent. This is one of the most basic rights you have as a citizen.
