According to "West's Encyclopedia of American Law, edition 2 Copyright 2008", I would suggest that the learned Judge was correct in querying Schuck's grasp of the subject matter.
After having perused numerous law sites and their definitions of the terms involved, (purely for the educational benefit of my fellow AvCanadians) I believe it can be stated with a fair degree of certainty that according to at least one of the following definitions most of us are guilty of said offences, possibly even the OP.
(It seems I myself am doomed to cross the river Styx due to "oral copulation". It will be a solitary crossing. Sadly, with remuneration in aviation being as it is, I fear many of my AvCanadian brethren won't even have a coin left over to pay the boatman.)
I suspect that Justice Marshall Rothstein will have the last laugh here as the items are somewhat different historically. The definitions have now almost merged in popular literature but retain a certain distinction which I am sure a Supreme Court Justice can see clearer than a lay person.
(Note: The following is from US law, but the history of the law is the same as in Canada until it was repealed)
To wit:
1) Buggery:
The criminal offense of anal or oral copulation by penetration of the male organ into the anus or mouth of another person of either sex or copulation between members of either sex with an animal.
Buggery is historically referred to as a "crime against nature." It is an offense under both Common Law and statutes. Although prosecution for buggery is rare, the punishment upon conviction can be a fine, imprisonment, or both. The term is often used interchangeably with Sodomy.

2) Sodomy,
Anal or oral intercourse between human beings, or any sexual relations between a human being and an animal, the act of which may be punishable as a criminal offense.
The word sodomy acquired different meanings over time. Under the Common Law, sodomy consisted of anal intercourse. Traditionally courts and statutes referred to it as a "crime against nature" or as copulation "against the order of nature." In the United States, the term eventually encompassed oral sex as well as anal sex. The crime of sodomy was classified as a felony.
