Yesterday someone stole my bag which has all the important immigration documents like PR card, All work permit and passport but luckily all were photocopies and originals are still with me.
Can they still be misused? Should i be worried about it?
Of course they can be misused - someone stole photocopies of your identifying information. Make a police report, contact IRCC to tell them, and contact anyone else who issued a document where a copy was stolen (passport, credit card, etc)
