Hello mhakhaou - my sister had the same case ("reckless imprudence resulting to damage to property") that was dismissed more than 10 years ago. her application was approved and they are now PR in Canada.
This is what we did - we filled out the Court Records Retrieval Request form - we paid the fee and then scanned this form and OR - we used this as first page cover to court records, affidavit. we submitted them all as one file in GCKey. we also added a scan of the page on the court ledger that contains handwritten notes about the case.
If the court no longer has copies of your case documents, ask them to write it on their letterhead and include the reason (e.g. flood, fire, institutional policy to destroy records that are more than 10 years old for minor cases etc ).
In my opinion, if your dismissed case involves damage to property only and no injury to the other party, you should be okay. Just provide all court records.
