@sumitbajaj07 for your views too, i paid special attention to these points......
1 - not try to continue with previously half-filled application; fresh shuru kari (there's some limit of no. of days too within which it has to be completed)
2 - ALL INFO AS PER PASSPORTS - apni, maa baap n biwi ki, with spl attention to middle names n how place of birth is spelt
3 - passport section right under family details to have Canadian pp info
4 - mode of Canadian citizenship - naturalization, date - date on citizensh cert
5 - relationship with root Indian - self, cos we all had IN pps
6 - family in India - only immediate family - siblings/parent
7 - date of marriage regn - $#%%^%&$%$#$@%$@%$^$Y^*(
documents to take along - yet to figure out
