On May 25, 2019, Riviere was named to Canada’s women’s national team roster for the 2019 FIFA Women’s World Cup in France, before which Riviere had only recorded five caps (career international appearances). Just 24 hours before Canada’s second game against New Zealand, Riviere, Team Canada’s second youngest player at the time, learned that she would be starting the game at right back (defender), replacing Allysha Chapman, who played every minute of Canada’s 2015 World Cup run. The match against New Zealand was Riviere’s second career international start. Overall, in the 2019 FIFA Women’s World Cup tournament, Riviere played in three games (one start, two substitutions). In total for Canada’s senior national team in 2019, Riviere played in eight games (three starts, five substitutions) and accrued 321 minutes played.
