If she's busy with her grandchild, then in CIC's eyes, she's already working illegally. I totally agree with you, I think it's silly to refuse a family member for that reason, as almost every family would have a relative watch their kids. It's normal in Canadian society. However, that's not how CIC sees it.
Honestly I don't have a clear answer for you. I don't know if we have a caregiver shortage in Canada due to not many people liking the job, or if there is an abuse of the live-in caregiver program.
Again, I'm definitely not speculating about this. I've personally seen on this forum, with ACTUAL people going through this experience, and what they've told me, both through private messages and publicly. I've even seen their GCMS notes sometimes. I'm not a super expert, but I have definitely gone through this experience myself.
My wife is a citizen of Vietnam (a country which is difficult to get a visitor visa from), she was married to me at the time she applied for the visitor visa, also had her spousal PR application pending (by the way, you frequently mentioned in your old posts that the chances of getting a visitor visa are slim when a spouse is in Canada). And guess what? She not only got the visitor visa, she got one that's valid for the life of her passport and when she landed, they allowed her 6 month entry. Basically, she got the best possible result, despite the odds stacked against her, and the frequent comments by other forum users here saying it's impossible to get a visitor visa. Although part of the reason for the visa might have been luck, both of us spent 3 days compiling our documents and constantly exceeded the 4MB file limit, that we had to compress our font, remove some pics, to make the file fit. We absolutely did all our power to show she will not overstay, and my wife was then granted this TRV.
And another thing that might surprise you as well. My mother-in-law, who is also from Vietnam, is applying for a supervisa to come here. And just this morning, she got approved for a 10 year visa, which is the maximum allowed for a super visa. And once again, I helped prepare her application, and did everything I can to show she will not overstay or work illegally. My wife's due to give birth in June, and we stated on the purpose of visit that my mom in law will NOT be taking care of our child, but rather she will simply spend time with us and our family. To further drive home that point, I mentioned on the application that my mom in law won't be working illegally taking care of our child since my wife will also be staying at home with the baby, my mom in law is just simply there for support and being with us.
I don't consider myself an expert in visitor visas, but I've not only witnessed what other forum users have gone through, but I've also gone through the process myself. As you can see, my wife and mom in law, both Vietnamese, both requiring biometrics to enter Canada (you know how hard it is to get a visitor visa when you're one of few countries that require biometrics to enter, and Hong Kong doesn't even require biometrics), and yet both got the best results for their visitor visas. I always get a new message every couple days from someone asking for help with their visas, and I'm always happy when I help someone avoid an interview, or get approved. I don't know how much you yourself have experienced doing the visas, and you seem like an intelligent man, but it makes me a bit upset when you say that I'm "speculating" when I'm simply going off first hand experience.
So let's see, I got both women maximum length of stay for their visitor visas, my wife's only PR visa took only 6 months compared to 30 month posted time for Singapore visa office, maybe I'm just lucky right? Or maybe I just knew how to compile their applications to the best of my ability and prove to CIC that both women are not overstay risks? Yes that's right, I have first hand experience with this. I might not know every single thing, and I even sometimes post incorrect info, but this subject, I definitely feel I got it down.
Maybe I'm wrong, but I think maybe you're just bitter because your own mother in law was refused or you guys didn't do a good enough job to convince CIC your mother will leave Canada. That happens, sometimes you can have the best documents in the world and still be refused.
