In order to apply for Canadian citizenship you must:
You will be required to provide a police certificate for each country, other than Canada, where you were present for a total of 183 days or more during the four (4) years immediately before the date of your application.
For this calculation only, it does not matter if the absence was before or after you became a permanent resident of Canada. Each day spent outside Canada counts as a full day in the other country.
Once you obtain your Canadian citizenship, you will be entitled to all of the rights and freedoms afforded to Canadian citizens.
