Step One - the application

Fill in the online application form at this link.

Essentially there are two parts to the Form. Part A & Part B.
Fill in Part A online and then print the whole form. When you print it out, the Part A will already be filled in.

IMPORTANT: The information you fill in Part A should match exactly with what is in your Indian and Canadian passport.
If your Canadian passport spells your name as 'Beychaara' and it is spelt 'Baychaara' on your Indian passport - go get a new name change certificate.
If your birthplace is different then you need to get a new Canadian passport. Trust me.
I listed my birthplace as Lucknow in the Canadian passport and Uttar Pradesh in the Indian passport, basically I have to get a new Canadian passport that matches the birth place with the Indian passport - even though Lucknow is in Uttar Pradesh. They are pretty anal about place of birth being the same in both passports.
Do not think that you will be able to explain this to the officials - they will not listen so do not waste your time and do what you have to do.

But I don't have a printer at home?
You can print the form to a pdf document and save it on your computer. I would recommend you do this even if you have a printer at home. Once you have the pdf you can have it printed at 'Staples' or even at work.
