hI I found this info..
Non-Conviction
You do not need to apply for a pardon if charges against you were dismissed, stayed or withdrawn, or did not result in a conviction.
If charges did not result in a conviction, but your record is on the RCMP system you may contact the arresting police force and ask them to request that the RCMP return your fingerprints and all information taken at the time of arrest for destruction. The police forces may choose to deny this request.
Retention and Destruction of Non-Conviction Information - Adults
The RCMP has introduced a new Policy for the Retention and Destruction of Non-Conviction Information – Adults which outlines the criteria used by the RCMP to determine whether non-conviction information contained in the National Repository of Criminal Records is retained or destroyed. “Non-conviction information” refers to criminal charges with court decisions other than “guilty”. These decisions include acquittals, withdrawals, stays of proceedings, peace bonds, and findings of “not guilty”.
His case was 2006 apr. and it says withdrawn and stayed proceedings on the disposition..and on top of the clearance it's conditional and absolute discharges...And i'VE read also that absolute and conditional discharges (offences inside canada) are not inadmissible.
It says also at the RCMP site that absolute and conditional charges should be automatically purged after a year(absolute) and 3 yrs for conditional.....hmmm I hope I've read and understand it well.
