Canada

The key is to base eligibility

And that's how you know this is the usual contempt and hatred for Canadians behind a proposal trying to use the philosophical clout of UBI in a despotic corrupt way.

Their scheme is to reduce old age spending by forcing their kids to support their parents.

UBI is inherently a zero cost program. Government gets no say in what to do with any tax revenue meant for it, and does not pay for administering "eligibility". Its just another (refundable) tax credit that gets paid by higher taxes on others, but who also inherently qualify for UBI.

UBI becomes an easy cost savings program when other programs are eliminated. UBI that is higher than social programs and EI, means programs can be eliminated to the benefit of people both receiving them and not. Unconditionality means no poverty trap preventing them from seeking additional income. Eliminating crime and homelessness is such a massive quality of life increase to all, including tourism related businesses. Massive economic growth and wage (that multiplies economic growth even more) benefits of UBI, means that the rich get richer even after tax hikes.
