The tort of conversion involves a wrongful interference with the goods of another, such as taking, using or destroying these goods in a manner inconsistent with the owner's right of possession.
The tort is one of strict liability and accordingly it is no defence that the wrongful act was committed in all innocence.
Boma Manufacturing Ltd. v. Canadian Imperial Bank of Commerce,  3 S.C.R. 727, at para. 31.
NOTE: Conversion is the tort equivalent of theft in criminal law.
