Branstine represented the United States from 2014 to February 2017, but started representing Canada, the birth country of her mother, in March 2017.
Branstine was born in Irvine, California to an American father, Bruce, and a Canadian mother, Carol Freeman, from Toronto. She has two older sisters, Cassidy and Constance, both of whom play collegiate tennis. Her cousin Freddie Freeman is a professional baseball first baseman for the Atlanta Braves of Major League Baseball (MLB). Branstine accepted an offer from Tennis Canada to train at the National Training Centre in Montreal, starting in October 2016.
Branstine played her first junior tournament in November 2014 at the ITF G4 in Atlanta and won the doubles title. Two weeks later at the G4 in Boca Raton, she captured her first junior singles title and also won in doubles. In March 2015, she played her first professional tournament, losing to Karolína Stuchlá in the first round of the ITF 10K in Gainesville. In June 2015, she won the doubles title at the G4 in Haverford. Branstine qualified for her first junior Grand Slam main draw at the 2015 US Open in September, but lost to Evgeniya Levashova in the opening round. She also reached the second round in doubles.
In March, Branstine captured her second junior singles title with a victory over Ann Li at the G4 in Newport Beach. She won her third junior singles title in June at the ITF G4 in Plantation. In September, she reached the quarterfinals in singles of the junior US Open, upsetting the No. 2 seed Olesya Pervushina in the second round. In November, she advanced to the semifinals in doubles at the ITF 50K in Toronto with partner Elena Bovina. Also in November, she reached the doubles semifinals at the ITF GA in Mexico City. In December, Branstine made it to the semifinals in singles and to the quarterfinals in doubles at the Eddie Herr ITF G1 in Bradenton. The next week, she advanced to the semifinals of the ITF GA Orange Bowl.
In January at the junior Australian Open, Branstine reached the third round in singles and captured the doubles title with Bianca Andreescu. She started representing Canada officially in March and played her first tournament as a Canadian at the ITF G1 in Carson at the end of the month, where she went on to win both the singles and doubles titles. In June at the junior event of the French Open, Branstine lost in the opening round in singles, but won her second straight Slam doubles title with fellow Canadian Bianca Andreescu. In July at the G1 in Roehampton, she won the doubles title with Marta Kostyuk. The next week at Wimbledon, she lost in the quarterfinals in singles and in the semifinals in doubles with Kostyuk, ending her hopes of winning a third straight junior doubles Grand Slam title. In August at the Rogers Cup, she was awarded a wildcard in the doubles main draw with compatriot Bianca Andreescu, her first WTA main draw. They upset Kristina Mladenovic and Anastasia Pavlyuchenkova in the first round before falling to the first seeds Ekaterina Makarova and Elena Vesnina in the next round. At the junior US Open in September, Branstine was defeated in the second round in both singles and doubles. The next week at the Coupe Banque Nationale, she advanced, with compatriot Andreescu, to her first WTA doubles final where they were defeated by the first seeds Tímea Babos and Andrea Hlaváčková.
