Caniza has always been a regular in the Paraguay national football team because of his versatility, as he can play as a side defender or as a centre-back. After the 2006 FIFA World Cup, Caniza announced his retirement from the Paraguay national team. However, when coach Gerardo Martino took the helm of the national team Caniza was called back and accepted to return to play for Paraguay. After Gerardo Martino took the head coach job in the Paraguay national football team, Caniza was voted for his teammates to become the captain of the team, so every time he plays (when he is not injured or suspended) he captains the Paraguay national football team.
In December 2014, Caniza announces his retirement at the age of 40 and his intention to have wanted to retire at Olimpia Asunción.
