We have 2 children, both were born here, in Canada. My question is: should we include them in the application for the PR, since they are Canadians? I'm not sure about this. Please, help.
Yes, everyone whose kids are Canadians should include them in the application (which is logical ). Later, in the application process, there are questions about citizenship etc.
No, you should declare your Canadian citizen kids, but not include them in your application. Of course it doesn't do harm if you include them in the application except you would pay more money to CIC.
