To my knowledge, CBSA still has my old laptop and my new laptop, including any files on there. There are quite a number of recovery services available, either through the private sector or through others, to recover files and hard drives that have even been burned.
What services CBSA has undertaken so far, I can't speak to and I'm not aware of; although, I know there's an investigation. I think, more importantly, as I said at the beginning, these emails do not exist on only this laptop, but anybody I sent an email to or anybody cc'd would still have copies. Anybody who sent me emails that they would like to provide as evidence, even if they were presumably gone from my laptop, could provide it and say, “I sent this email on this date to Mr. Doan”, and all these other people cc'd would have a copy as well. There are a number of measures possible as well as some of the backups that would be available on Shared Services' servers because the email was not managed by CBSA.
