How to apply for Canadian citizenship after permanent residency

You need to have stayed in Canada for a total of 3 years out of the last 5 years, file taxes, and be able to show evidence of language and residency requirements. One can apply with a complete set of documents, take the citizenship test, and attend the oath ceremony to become a citizen. After that, you get your certificate of citizenship, which gives you the right and privileges to be a full citizen of Canada: working opportunities, giving your children the citizenship. That is pretty easy if you meet criteria.
