Singapore is nonsensical, because that’s a completely different jurisdiction.

For Ottawa-specific laws, there is probably no real choice but to stay in Ottawa. For provincial and federal laws, there are options. I don’t necessarily agree that change of venue should be a given, but it is a commonly accepted means of trying to ensure impartiality. I’m not sure that there is anywhere in Canada where this trial could be conducted without the spectre of bias, but, whether we like it or not, change of venue is one of the tools available.
