What is the impact of a Mareva injunction on the assets of a fraudster?

I am referred, amongst other authorities, to the recent decision of Mr. Justice Myers in Lonneberg v. Onca, 2021 ONSC 6196, in which Justice Myers emphasized the importance of enforcing Mareva injunctions, saying this at paragraph 40: Mareva injunctions must be rigorously enforced. A fraudster is not likely to be dissuaded from his greed and criminal bent by a piece of paper or a computer screen displaying a fancy red seal. If victims are to be able to obtain the enforceable remedies and compensation that the law promises, the court’s Mareva injunctions freezing assets and requiring asset disclosure must be enforced with the court’s full arsenal of authority and power. Otherwise, Canadians are sheep waiting to be fleeced.
