My grandmother was from Nova Scotia. Lots of family still there today. She came to Boston to study Nursing in the 1910’s and never left. She spoke fluent French. A cousin researching that side of the family connected with another branch of the family who traced their roots back to France. Anyway, my family growing up visited Nova Scotia, and I remember driving up to Montreal, as well.
In light of this thread, I thought I would try to research a little bit of why student nurses were sent from Canada to study Nursing (as they sometimes were from various other countries during different times over the years such as Ireland, China, Russia and the Philippines, as examples).
Here’s what I got in the short time I had yesterday (as I am working this weekend; she was the first, that I know of, of four generations of nurses in my family).
Apparently, before there was the American Nurses Association, there was the
Nurses’ Associated Alumnae of the United States and Canada (1896-1901). So there was a formal association there

likely due to shared camaraderie in service during wars of the 19th century.
Boston and Nova Scotia formed an alliance which exists to this day (with their still sending a tall spruce tree down to erect on the Boston Common every December, in perpetual thanks for doctors and nurses from Boston rushing up there to help with the tremendous devastation from the
Halifax Explosion in 1917, as well as great financial assistance from the state of Massachusetts). It’s a nice tradition here and makes the nightly news every year.
The following year, as their community was still recovering from the Explosion, nurses from Halifax “repaid the debt” by rushing to Boston during the Spanish Flu Epidemic of 1918 when that city was hit particularly hard and sent out an SOS for help.
“At least 32 Nova Scotia nurses worked in Boston in the fall of 1918. Research shows at least 12 made the ultimate sacrifice, dying of the very flu they were fighting.“ 
This is a very interesting article about that experience, and there are many uncanny similarities to what we are seeing today from a medical standpoint.
The Nurses Who Repaid Halifax’s 1917 Debt To Boston.
So somewhere in that time period, when my grandmother was a young woman, she, too, wound up in Boston, from Halifax, to answer the call to duty.

I got to speak to her shortly before she passed, when I was in nursing school myself, about her experiences. It was fun to hear what she had to say - boy, I wish I could’ve recorded it! And I would definitely have some follow up questions today in light of this new (to me) information. My guess is that she either had a relative or family friend who was working in the hospital system there and they put out the word that it would be a good opportunity for her, which is what I’ve heard from other nurses I know who came from other countries to work as nurses. My friend from China was chosen as a very young girl to study science because she had excellent grades, and was one of a very few nurses chosen to come to the U.S. to work.
