Yes, they can I believe. I had my phone seized once and they did a celebrite download. They advised me the phone was going to be forfeited to the crown (basically I never get it back). I had a duty lawyer represent me and request my phone be returned due to a few reasons e.g. I was young and needed my phone, stuck in a contract for x amount of months, how much the phone was costing me per month, etc.
I would talk to your lawyer and ask them if they can request it back since they've done what they needed with it.
