Aaron Driver, 23, is not facing criminal charges but federal authorities were seeking a peace bond to limit his activities on the suspicion that he may help a terrorist group or activity.
Driver had been released on bail until the court decided whether to issue the peace bond.
He was released into the custody of a woman on $1,500 bail and required to live at her home, among other conditions, but that woman has now withdrawn her financial support and Driver was re-arrested Friday afternoon.
Published reports have said Driver posted messages on social media that praised terrorist activities, including the attack last October on Parliament Hill by Michael Zehaf Bibeau.
His next court date is July 9.
