@reginafacenda 5. TEMPORARY SINs
SINs that begin with the number 9 are issued to temporary residents who are neither Canadian citizens nor permanent residents, such as foreign students or individuals on work visas. These SINs have an expiry date.
6. GEOGRAPHY OF NUMBERS
The first digit of the SIN identifies the province where it was registered. 1 covers Atlantic Canada (Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador), and overseas residents. 2-3 is used in Quebec. 4-5 is used in Ontario, excluding northwestern Ontario. 6 is for prairie provinces (Manitoba, Saskatchewan and Alberta), Northwest Territories, Nunavut and northwestern Ontario. 7 is used in the Pacific region (British Columbia and Yukon). 8 and 0 are not used.
By the sounds of this i assume they mean 9, because no SINs start with 0
EDIT: Additionally, people whose social insurance number begins with “09” don’t meet the
Netfile requirements. This number applies to temporary workers who are not citizens or permanent residents. Those with an address outside of Canada, non-residents, and people who recently emigrated to the country, also don’t meet the qualifications to use Netfile.
They for sure mean 9
