Yes my husband did not me. But I don't think that it is an issue. Because I know a lot of people from my country who invited their parents with asylum even their parents had never travelled abroad, had no jobs or were pensioners, had no house on their names but they got the visitor visa from first or sometimes second attempt . My friend applied at the same time with me for her mother and mother-in-law. Her mother-in -law was rejected even though she has a house and a car on her name, job and bank account with 11k Cad, but my friend's mother's visa got approved and she had only 3k CAD on her band account no job no house.
This is unfortunate but I believe this is main reason
Every case worker is different. and you can't put some standard Rule on this
Ex: When we applied for our PR 8 years back one was requirement Employer letter . Few organization don't provide any such letter for Immigration (PR) purpose.
Out of many of us explained this while submitted PR Application , Few got PR approved , and few got rejected based on this missing document .
Now it all depend who is working on your File and how case worker is looking into this. (You can not challenge on this)
its not some written rule for few of things for Immigration purpose
Good Luck
