Janine Beckie scored the first goal but host Brazil responded with three of its own, including two from Monica, for a 3-1 victory over Canada on Sunday in the final of the international women's soccer tournament in Natal.
Monica's first goal of the game, on a header off a corner kick in the 63rd minute, stood as the winner as Brazil remained undefeated in the four-team tournament.
"I think the girls gave it everything they could tonight," said Canadian coach John Herdman. "Brazil just had a little bit more quality on the attack, whether it was with their set pieces or delivery."
Canada finished second after going 2-1 in group play. The Canadians' only other loss of the tournament was against Brazil in the final game of the preliminary round.
Beckie opened the scoring in Sunday's game with a shot on the run down the left side early in the second half.
Less than a minute later, Brazil tied the game on a goal from Andressa Alves. Alves was given a yellow card when she celebrated her goal by running up a set of stairs to hug her family.
Monica made it 3-1 on another header from a corner kick with 10 minutes remaining in the second half.
"We know with Brazil that you have to open yourselves up a little bit to get something off them," said Herdman. "There were two great chances in the second half, and had we capitalized on them the game could have gone a totally different direction."
Four teenagers made their first appearances for Canada's national "A" squad in Natal — Gabrielle Carle (17), Kennedy Faulknor (16), Marie Levasseur (18), and Deanne Rose (16).
Canada's next international tournament will be the 2016 CONCACAF women's Olympic qualifying tournament in February.
