This is wrong information. To apply for citizenship, you need the following:
1. Satisfied the residency days/physical presence requirements for citizenship.
2. Satisfied the conditions to maintain PR. (Residency days conditions)
3. Have an address in canada (Non PO box address)
4. No criminal proceedings
The user quoted is referring to the condition for counting residence days outside Canada to meet physical presence requirements for citizenship. Ex: If i lived in Canada for 3 years as a PR and moved to India, I am eligible to apply for citizenship. If I can collect the documents for citizenship applications, have an address in Canada and can fedex them to CIC, i can kick start the process for citizenship application. Now, I have to be in Canada for oath and citizenship ceremony.
