Preference will be given to Canadian citizens. Please indicate in your application the reason for which you are entitled to work in Canada: Canadian citizenship, permanent resident status or work permit. More useful information about Citizenship requirements can be obtained on the Public Service Commission web site.
Even if you are not a Canadian citizen, you are still entitled to apply and be considered for positions, in cases where there is an insufficient number of potentially qualified Canadian citizens.
