Note that discrepancies may be observed when running more than one instance of the tool. The location in which events are occurring may differ due to the randomization of the modelled data.

Some demographic events of the population clock (emigrants and non-permanent residents) are modelled as a net number in order to facilitate the calculations.

A net emigrant is calculated by adding emigration and net temporary emigration and by subtracting return emigration.

Net non-permanent residents represent the variation in the number of non-permanent residents. This variation can be positive or negative. A non-permanent resident is a person who is lawfully in Canada on a temporary basis under the authority of a valid document (work permit, study permit, Minister's permit or refugee) issued for that person along with members of his family living with them. This group also includes individuals who seek refugee status upon or after their arrival in Canada and remain in the country pending the outcome of processes relative to their claim.
