Last Updated: August 27 2026
Question: Can a paralegal help me sue for trespass to chattels if someone wrongfully interfered with my personal belongings in Ontario?
Answer: A paralegal at PKM Legal Services can help you assess whether your situation fits trespass to chattels by focusing on wrongful, direct interference with your possession or control of a chattel (like an automobile or household items) rather than taking it from your possession as in conversion or detinue. You can generally claim actual loss from the damage (like devaluation) and, depending on the circumstances, possible general and punitive damages where the interference was troublesome, emotional, or malicious. If you explain what happened, what property was involved, and what losses you suffered, PKM Legal Services can guide you on next steps and evidence to gather, so call (519) 410-5250 today.

Wrongful Interference With Personal Belongings
Trespass to chattels involves wrongful harm by interference with chattels, chattels being legally defined as objects unattached to land that include personal belongings such as household furnishings, artwork, clothing, appliances, among other things, as well as commercial belongings such as moveable machinery, goods for sale as inventory stock, animals as livestock, among various other objects.

The Law
Trespass to chattels is similar to conversion and detinue whereas all three relate to wrongful interference with a chattel; however, the distinguishing nuance with trespass to chattels is that the object remains in possession or control of the owner or person with rightful possession which differs from conversion and detinue where the owner or person with rightful possession is deprived of possession. Perhaps the easiest way to explain the difference is to use the criminal law term in that conversion or detinue may arise from theft (criminal law term) of the object, being interference by removing the chattel from the possession of the rightful owner or person with right of possession and trespass to chattels may arise from vandalism (criminal law term) being interference without removal of the chattel.
The elements necessary to give rise to the tort of trespass to chattels were well articulated in Ontario Consumers Home Services v. Enercare Inc., 2014 ONSC 4154, where it was stated:
[50] In Hudson’s Bay Company v. White, [1997] O.J. No. 307 (Ont.Gen.Div.) Lederman J. at para. 8 referenced the criteria necessary for trespass to chattels:
In Clerk and Lindsell on Torts, 17th ed. (London: Sweet and Maxwell, 1995), at p. 705, the authors define trespass to chattels, or “trespass to goods”, as being concerned with “the direct, immediate interference with the plaintiff’s possession of a chattel”. Halsbury’s offers a similar definition at Vol. 45, para. 1491: “Trespass to goods is an unlawful disturbance of the possession of goods by seizure or removal, or by a direct act causing damage to the goods”.
Claimable Damages
Where chattels, such as an automobile as a personal belonging, or other thing, is harmed per the law of trespass to chattels, a lawsuit may make claim for the resulting actual loss suffered, meaning the devaluation of the object as a result of the harm to the object. Furthermore, depending on the circumstances, especially where the trespass was troublesome and emotionally disruptive, general damages may be appropriate; and additionally, where the trespass was intentional or egregiously malicious, punitive damages may be applicable.
Conclusion
The tort of trespass to chattels is found within the family of interference torts which include, among others, the torts of conversion and detinue. The key difference with the tort of trespass to chattels and the tort of conversion or the tort of detinue, is that with trespass to chattels, the chattels, meaning goods or personal belongings, remain with the rightful owner or person with rightful possession.
