What are some strengths and weakness of the current Canadian immigration policy?

A few different points would be best.
Answers:   
Strengths: They don't let just anybody in; have a relative there is not enough; they have a points system for age, rearing, etc.

Cons: They are too restrictive with age, which leaves out a lot of skilled people over 50; they lose greatly of artistic types who may not have education or means within the traditional sense.
