My son was from Preschool to JK at Sidney Ledson, at the end of Pre-K he was reading at the end of JK he was a proficient reader, he had 10 word's quiz spelling test every week his vocabulary grown tremendously, the school was convenient at that time for my because was 5 minutes away from work, sadly my company is located now in Mississauga. Then he went to a school closer to home for SK, his teacher told me that he already knew all the curriculum for SK. He just finished G1 at French immersion school doing excellent, mostly because Sidney Ledson was the foundation of his education. SLI staff is on top of every children, the only con is that there was not outdoor playground, to balance this situation the principal provide after program classes (for additional fee) such as martial arts, ballet and chess club. Forgot to mention that they teach them piano no extra charge as part of learning program. Overall excellent school and for the same price of a regular daycare.
