It also marks a tiny decline in the proportion of women holding portfolios compared to the Liberal cabinets under then prime minister Paul Martin.
Martin named 11 women to his 39-member cabinet in 2003 and had nine women among the 37 MPs holding portfolios when his government was defeated, representation rates of 28 per cent and 24 per cent, respectively.
Women make up about 22 per cent of the new 27-member Tory cabinet, which was sworn in at the Governor General's official residence in Ottawa on Monday morning.

Another prominent Tory in Harper's cabinet is Edmonton's Rona Ambrose, who is fluent in several languages and served in Harper's shadow cabinet.
Ambrose, one of the youngest MPs at age 36, was touted during the last election campaign and widely considered a sure bet for cabinet. She becomes minister for the environment.

Prominent Calgary MP Ablonczy omitted from cabinet
One high-profile MP who was touted for a cabinet position but didn't make the cut was Diane Ablonczy, a party stalwart from Calgary who most recently served as the Tory's immigration critic.
In an interview with CBC News, Ablonczy said she discussed the matter with Harper and was told that she wasn't chosen because the party had so many other prominent Alberta Conservatives vying for portfolios.
"There cannot be too many of us from Calgary and that was a sad fact of life," said Ablonczy.
She said Harper had made it clear that he respected the work she had done for the party and asked her to be parliamentary secretary to the finance minister.
There are 14 women in total among the 125 MPs.
