The accused was charged with four counts of possessing explosive substances and one count of counselling mischief not committed, arising from his activities prior to the G20 Summit in Toronto.
Police found various chemicals and laboratory equipment in his home, which the Crown alleged were intended to make explosive substances.
The accused maintained the chemicals were for innocent purposes, including amateur rocketry, gardening, and testing the security system.
The court found the Crown failed to prove beyond a reasonable doubt that the accused intended to create explosive substances, accepting that his interest in rocketry and other hobbies raised a reasonable doubt.
On the counselling charge, the court found the accused's tweets about design flaws in the G20 security fence merely described how mischief could be committed but did not actively induce or advocate the commission of the offence.
The accused was acquitted of all charges.
