Could this be "The Screwfly Solution" by Raccoona Sheldon? (AKA Alice Sheldon, AKA James Tiptree Jr.)?
Per wikipedia, the main character is a researcher working in South America. At the end she's hiding out in Canada which she describes thusly:
"Up north, Anne was biting her lip in shame and pain."
The story begins with an exchange of letters and news clippings
between Alan, a scientist working on parasite eradication in Colombia,
and his wife Anne at home in the U.S., concerning an epidemic of
organized murder of women by men. Some scientists suspect a biological
cause for this sexually selective insanity (selected observations of
lab animals indicate that the normal male sexual urges are spiraling
out of control, resulting in death), but the murderers feel it is a
natural instinct and have constructed elaborate misogynistic
rationalizations for it. For example, a new religious movement is
spreading along with the murders: the Sons of Adam, who believe that
women are evil, that the garden was a paradise before women were
introduced, and that God is telling them to get rid of all of the
women. When the religion initially arises, prior to the organized
murders, little is done to stop the ideology's spread, nor are their
actions of evicting women from the areas the men control prevented.
Alan realizes that the disease causes male sexual impulses to instead
become violent impulses.
Alan, a sensitive, kindly man, realizes that
he himself is succumbing and tries to resist the impulses, as well as
isolate himself from women. While this occurs, his wife and teenaged
daughter have a number of mother-daughter conflicts: the daughter,
faithful to her father, refuses to believe her mother's warnings about
him. She sneaks off to visit her father, and he murders her, killing
himself after the horrific realization of his action. Anne flees
north, to Canada, since the disease began in the tropical zones and
spread outward. After most of the world's women are dead, adult men
start murdering boys.
In the end, Anne, pursued by an entire society
bent on femicide, discovers the source and motivation behind the
plague: an alien species is intentionally causing the human race to
destroy itself so that the aliens can have Earth for themselves.
The sole example I can find of it being collected with other female authors is in the very recent "Sisters of the Revolution: A Feminist Speculative Fiction Anthology" from 2015, but this work has been repeatedly collected and is always been lauded as a strong example of female-orientated science fiction since it was first published in the late 1970s.
