The B.C. Criminal Justice Branch says Tak Leng Daniel Lee is accused of assaulting a peace officer, mischief and taking part in a riot, while Jesse Opper faces charges of mischief, taking part in a riot and using a mask to commit an offence.
The latest charges bring the total number of people accused of taking part in the June 2011 riot to 366.
Many of those, 274 people, have already entered guilty pleas, including all the juveniles who were involved.
The branch says six of seven people who went to trial were convicted and one person was acquitted.
A justice branch statement says two dozen people are awaiting sentencing.
