Is it ok to use both 301 redirect and rel= “canonical’ at the same time?

Hi everyone,

To fix the problems in our website considering duplication I have the possibility to set up 301′ s and, at the same time, modify our CMS so that it automatically sets a rel= “canonical” tag for every page that is generated.

Would it be a problem to have both methods set up?

Is it a problem to have a on a page that is redirecting to another one?

Is it advisable to have a rel= “canonical” tag on every single page?

Thanks for read!
