Here is how they all stack up by time in office - underlined means currently in office, bold means won at least one election.
- Eva Aariak Nunavut 1827 days
- Christy Clark BC 1715 days
- Nellie Cournoyea NWT 1469 days
- Catherine Callbeck PEI 1353 days
- Kathy Dunderdale NF 1148 days
- Kathleen Wynne Ontario 1016 days
- Alison Redford Alberta 898 days
- Pat Duncan Yukon 884 days
- Pauline Marois Quebec 581 days
- Rita Johnson BC 217 days
- Rachel Notley Alberta 183 days
- Kim Campbell Federal 132 days
Next March Christy Clark will become the longest serving female first minister in Canadian history.
Each time I have looked at this I have considered how many person days each first minister has governed for - this is time in office multiplied by population governed. I think that in many ways it is a better measure of the relative impact of women in politics. As you can see Kathleen Wynne tops the list when you calculated it this way.
The number is person days governed
- Kathleen Wynne Ont 13,057,000,000 Lib
- Christy Clark BC 7,546,000,000 Lib
- Pauline Marois Que 4,582,000,000 PQ

- Nellie Cournoyea NWT 92,000,000 na
- Eva Aariak Nu 58,300,000 na
- Pat Duncan Yk 24,800,000 Lib
What is also interesting is that four of the women did significantly better than expected in their elections - that being Alison Redford, Christy Clark, Kathleen Wynne and Rachel Notley.
On the other hand two women were forced out of the office of premier in an atypical manner early on in their first term as elected premier.
