The problem I faced with your method is:
1. When you go to the PassportIndia.gov.in website, it asks the Country you've gained Citizenship from, and I selected 'Canada' (THAT is what put the Toronto Consulate in my form.
2. When I entered my current address (which of course is in the US) , it took me to the Houston Consulate page/instructions 😡😟
3. So basically, I had: a CGI Application specifying Toronto Consulate, and a Renunciation Application meant for the Houston Consulate
