The veteran goalkeeper has played just once for Harry Redknapp's side this season and is set to join the likes of Jermain Defoe in Major League Soccer ahead of the 2014 World Cup
The Brazil No. 1 joined QPR in the summer of 2012 but has featured just once - in an FA Cup defeat to Everton - following relegation to the Championship, with manager Harry Redknapp preferring Robert Green.
Cesar has been selected for the March friendly against South Africa and is set to gain some valuable playing time in MLS ahead of the 2014 World Cup on home soil.
"Julio is in our group [for the South Africa game], he should be officially introduced to his new club," Scolari told reporters. "Toronto should be finalizing the last few details, and he should be in great condition. There will be no problem with him.
"Lots of players arrive in the United States thinking it will be easy and then end up not playing. They stay for four or five months and then leave. We wish he were playing and now he will be. The MLS is not the end of [a] career."
Brazil technical coordinator Carlos Alberto Parreira added: "The MLS is technically not one of the best in the world, but it is very competitive. It was really important for us that he played.
"Julio played the last match for us and he hadn't been playing. He was really well, playing well, his reflexes were all perfect. If he plays 10, 15 matches until the World Cup it will be great. And he has that quality of still being the same player despite not being active."
Toronto recently announced the signing of Tottenham striker Jermain Defoe, who will join the club at the end of February, and American midfielder Michael Bradley.
