I am unsure how one can disagree with a fact.  Very odd.

The crime of rape has very specific elements and  was defined as follows prior to 1982:

"Criminal Code, R.S.C. 1970, c. C-34, s. 143.

Rape
143. A male person commits rape when he has sexual intercourse with a female person who is not his wife, 
    (a) without her consent, or
    (b) with her consent if the consent
        (i) is extorted by threats or fear of bodily harm,
        (ii) is obtained by personating her husband, or
        (iii) is obtained by false and fraudulent representations as to the nature and quality of the act. 1953-54, c. 51, s. 135.

That formulation proved problematical on a number of grounds in the courts.

"Rape" was abolished in 1982. The same statute created the offences "Sexual assault," "Sexual assault with a weapon, threats to a third party or causing bodily harm," and "Aggravated sexual assault."
