I agree but I asked in general. OK and In specific I'm asking for sinp. I have ITA, already provided loe about the name concern but was just curious if this may become an issue. Although, I asked passport authorities in India they have put the application on hold and told once person is no more you can't modify the name.
In general it's not a problem esp if disclosed to IRCC (eg by means of letter of explanation). They seem to be aware that name issues are common with docs like these (esp in certain countries, incl notably India).
Could be an issue if they think there's some dishonesty behind it and/or it causes problem identifying individual. I don't think they start with assumption there is a problem but - as with any background-check type thing - the more inconsistencies, the more checks and delays it might lead to.
All a bit hypothetical of course.
