The game is a "milestone" for the league, designed to grow the popularity of the women's sport outside the United States, Commissioner Cathy Engelbert said, amid repeated calls for the league to expand.
"I’ve spoken often of the global popularity of women’s basketball and, this past season, WNBA games were broadcast in 207 countries and territories, including in Canada, where fans have shown a great appetite for WNBA action," Engelbert said in a statement.
"We’re looking forward building on the momentum."
It is only the third time that a WNBA pre-season game has been played abroad, after games in Monterrey, Mexico, and Manchester, England, were held in 2004 and 2011, respectively.
