n. — Alberta, Administration
an identification card proving eligibility for government-provided health care.
Type: 5. Frequency — While not a nation-wide Canadianism (see Chart 1), the term qualifies as a regionalism because it is the established term in Alberta (see Chart 2, see the 1992 and 2014 quotations). In the three Canadian territories, the term also has considerable currency. The term is an older variant (see the 1978 quotation) that was institutionalized in these regions. As the quotations and Chart 2 show, the term is occasionally used elsewhere in Canada.
