New immigrants in Canada are all 70-year-olds. Can they enjoy Canadian benefits?

If he is 70 years old, his son or daughter will make sure that he will come here. At the time of guarantee, he signed a written decision to be responsible for the 70-year-old man for everything in 10 (usually starting from 7- 10, depending on the immigration officer at that time). As for other benefits, he can certainly enjoy them. There is no problem, but the problem lies in the welfare.
