When i first came to canada and applied for work permit at port of entry i answered no about criminal convictions as my police record was clean. However when i received a new police certificate to apply for PR it came back with no live trace meaning i have an old record. When i applied for PR i sent a letter explaining ten years ago i had received a warning from police for marijuana possession. Well i be denied PR due to misrepresenting myself on work permit even though i told the truth on my PR application?
