Improper Pleading of Evidence Details:
Statements Containing References to How a Fact Will Be Proven
Last Updated: July 03 2026
Question: What should I include in an Ontario civil court pleading, and what details about proof should I avoid under the rule against pleading evidence?
Answer: A civil pleading for a claim or defence in Ontario should include a concise statement of the material facts you rely on, but not the evidence or proof details you plan to use at trial to prove those facts. In practice, keep your pleading focused on the constituent elements and the facts that are provable at trial and can affect the determination of your rights, and leave out how you will prove the point, because Ontario’s Rules of Civil Procedure require material facts without evidence by which those facts are to be proved, per Rules of Civil Procedure, R.R.O. 1990, Regulation 194, at section 25.06(1). Courts distinguish material facts from evidence as a matter of degree, and pleadings that effectively describe proof may be struck, including in Carducci v. Canada (AG), 2022 ONSC 6232; Jacobson v. Skurka, 2015 ONSC 1699; and Stedfasts v. Dynacare, 2020 ONSC 8008.

Understanding the Rule Against Pleading of Evidence
A pleading document, whether such is the claim document or a defence document, is to contain allegations of fact without containing details of the evidence that will be used to prove the allegations of fact. Simply said, the pleading document should state the facts as if the fact is true without stating how the fact will be proven true.
The Law
The Rules of Civil Procedure, R.R.O. 1990, Regulation 194, mandate that pleading documents contain factual statements only without containing details about how the factual statements will be proven wherein it is specifically stated:
Material Facts
25.06 (1) Every pleading shall contain a concise statement of the material facts on which the party relies for the claim or defence, but not the evidence by which those facts are to be proved.
Interestingly, confusion can sometimes arise as to what is a statement containing a material fact and what is a statement containing evidence. Clarification of the difference can be found within various case law decisions including:
[71] Rule 25.06(1) distinguishes between the “material facts” and “the evidence by which those facts are to be proved”. The prohibition against pleading evidence is designed to restrain the pleading of facts that are “subordinate” and that “merely tend towards proving the truth of the material facts.” See Jacobson v Skurka, 2015 ONSC 1699 at para 43.
[30] Material facts include facts that the party pleading is entitled to prove at trial, and at trial, anything that affects the determination of the party’s rights can be proved; accordingly, material facts includes facts that can have an effect on the determination of a party’s rights.[6] A fact that is not provable at the trial or that is incapable of affecting the outcome is immaterial and ought not to be pleaded.[7] A pleading of fact will be struck if it cannot be the basis of a claim or defence and is designed solely for the purposes of atmosphere or to cast the opposing party in a bad light.[8] As described by Riddell J. in Duryea v. Kaufman,[9] such a plea is said to be “embarrassing”.
[31] “Material” facts include facts that establish the constituent elements of the claim or defence.[10] The causes of action must be clearly identifiable from the facts pleaded and must be supported by facts that are material.[11]
[32] A pleading shall contain material facts, but it should not contain the evidence by which those facts are to be proved.[12] Pleadings of evidence may be struck out.[13] The prohibition against pleading evidence is designed to restrain the pleading of facts that are subordinate and that merely tend toward proving the truth of the material facts.[14]
[44] A pleading should not describe the evidence that will prove a material fact; pleadings of evidence may be struck out: Sun Life Assurance Co. of Canada v. 401700 Ontario Ltd. (1991), 1991 CanLII 7050 (ON SC), 3 O.R. (3d) 684, [1991] O.J. No. 915 (Gen. Div.). The difference between pleading material facts and pleading evidence is a difference in degree and not of kind: Toronto (City) v. MFP Financial Services Ltd., [2005] O.J. No. 3214, [2005] O.T.C. 672 (Master), at para. 15. What the prohibition against pleading evidence is designed to do is to restrain the pleading of facts that are subordinate and that merely tend toward proving the truth of the material facts: Grace v. Usalkas, [1959] O.W.N. 237 (H.C.J.); Phillips v. Phillips (1878), 4 Q.B.D. 127 (C.A.). Even a pleading of an admission, which is a type of evidence, may be struck out: Davy v. Garrett (1878), 7 Ch. D. 473 (C.A.); Sun Life Assurance Co. of Canada v. 401700 Ontario Ltd., supra.
Conclusion
Within lawsuit documents, the pleading of material facts is proper; however, the pleading of evidence is improper. The pleading of evidence involves details about how a material fact will be proven.
