The 17-year-old male will live with his grandparents, wear an electronic bracelet and be subjected to a curfew.
The teenager -- who hails from Manitoba and can't be named under Canadian law -- will participate in counseling and be banned from using computers.
Active on Twitter, he pleaded guilty last September to encouraging an offense related to terrorism.
The adolescent, who converted to Islam, told investigators he would attack targets in Canada if he could not join IS group fighters abroad, the public broadcaster CBC reported.
He apologized in court yesterday for his actions, committed at age 16, saying he had been suffering from an identity crisis.
