Have you ever had to sign a tourist form that asks:-

1. Are you , or Have you ever been a member of a terrorist organization?
2. Are you, or Have you ever been a war criminal?

I think the above exercise is useless, like asking about Canadian values.

 The more intelligent system is to allow younger people to immigrate. They are much more likely to adapt, less likely to need medical care or welfare, less likely to feel their career suffered by taking a more junior position than they were used to. a 40 year old with teenage kids is going to have a harder time assimilating than a 25 year old whose kids are born in Canada.
