Thank you for reaching out.


Getting charged for weed possession is a serious offence and if the charges stick, it will have negative implications on your friend's life for many years to come. For 30+ years I have represented many young offenders facing drug charges in the GTA. Please have your friend contact me for an initial free consultation and we can discuss his/her options. In the meantime, please advise your friend not to talk to the police and do not provide or sign any statement. My direct contact info: Phone: (905) 886-9535 x 23 and my email is:
