The 23-year-old was picked up by Winnipeg Police Service members Friday around 5 p.m. CT at a home on Carlotta Crescent in the Charleswood neighbourhood, Manitoba's chief federal prosecutor Ian Mahon confirmed Friday night.
"I believe that Mr. Driver has been taken into custody as his surety withdrew," Mahon said, without providing further detail.
Driver was initially arrested and his rental home was raided earlier this month. Investigators invoked a section of the Criminal Code and obtained a peace bond to limit Driver's activities.
"Police may pursue the order [a recognizance] with conditions such as to keep the peace and be of good behaviour if they have reasonable grounds to believe that a person may commit a terrorism offence," the RCMP said in a statement earlier in June.
Driver was eventually released on bail, but with 25 conditions.
According to a recognizance document obtained by CBC News earlier this month, Driver was ordered to:- Wear an electronic monitoring device around the clock.
- Take part in "religious counselling" and forward the counsellor's name to RCMP.
- Follow an overnight curfew (from 9 p.m. to 6 a.m. daily) and stay at his home in Winnipeg's Charleswood neighbourhood. The home was raided earlier this month.
- Surrender any passports he has and not apply for any passport from Canada or any other country.
- Not possess any desktop, laptop or tablet computer. Any cellphone he has must be approved by RCMP, and the phone number must be submitted to police.
- Provide passwords and access to his cellphone at the RCMP's request, with "such requests not to exceed two times per month."
- Stay away from social media websites, including Facebook, Twitter, Kik, Surespot and Telegram encrypted chat.
- Have "no contact or communication directly or indirectly with any member of ISIS, ISIL, Islamic State of Iraq and Syria and Al Qaida in Iraq." He must also not possess anything bearing the logos or names of any of those groups.
CSIS, Canada's spy agency, has been tracking Driver's pro-ISIS activity on Twitter, where he uses the name Harun Abdurahman.
Driver has yet to be charged for anything.
Mahon said he expects Driver will be back in court Monday in Winnipeg.
