In that case, however, that means that there would be a trial here, in Canada, before a Canadian court, to determine the guilt of an individual accused of breaking the law in a foreign country, whose laws and offences are not necessarily the same as in Canada. The degree of evidence could be different.
Many situations come to mind in which it could be complicated to hold a trial in Canada before a court or a judge who is completely or quite unfamiliar with the rules that apply in the other country.
Does such a proposal not pose too many procedural obstacles?
