That is correct. The Canadians used this stance -- backed up by the Canadian Supreme Court -- that laws that proscribe discrimination (or, in this case, "discriminatory speech") on the basis of race also reflexively apply to "sexual orientation," a leap that has not yet been made by American courts.
From a Lifesite.com blurb on the decision that tarred Dr. Laura north of the border (third item down):
The decision is very disturbing to pro-family Canadians as well as others who respect the findings of peer reviewed scientific and medical research. Dr. Laura identifies homosexual acts as "aberrant", "deviant", and "disordered" in keeping with her Jewish Orthodox faith, but demonstrates her own brand of hard-nosed concern for the individuals who engage in such practices. Nevertheless, the C[anadian] B[roadcast] S[tandards] C[ouncil] would not recognize this separation of behaviour from the person: "Since the sexual practices of gays and lesbians define them as homosexuals and are inseparable from their personas, any attempt by [Dr. Laura] to justify her statements on the basis that she is speaking about the practices rather than the individuals must fail."
