3- rel=Canonical is not replacement of 301 Redirects
The critical difference between both is: a 301-redirect takes the visitor to the canonical URL, while a rel=canonical tag does not. Because rel=canonical is just a hint or signal to guide the crawler bots for which page should be taken as preferred.
