Team GB boss Hope Powell has admitted that Canada will provide "a different threat" when the teams meet in the Olympic quarter-finals on Friday.
Powell's side, who beat Brazil to top Group E, will take on John Herdman's side this evening, and she has praised Canada's organisation.
"Canada pose such a different threat. Brazil, are silky skills and flair, whereas Canada are organised and structured. It is about how we are going to break a team like that down," Powell told the BBC.
The winner will face the United States in the semi-finals.
