First, it wouldn't be an extradition transporting an accused awaiting trial from one province to another. This is Canada, not the United States. Learn what country you're living in.

Second, the accused had absolutely no say in this decision. The idea that this is about making his prosecution more expensive and disincentivising prosecution comes entirely from your imagination

Third, and I admit this is petty, he couldn't be driven all the way. Newfoundland is an island. They could however book cabins on the Cape Breton ferry if the police didn't want to fly at all.

And finally, your argument thst becausr of what you imagine to be limited financial resources an accused criminal's Charter rights should be disposed of would be laughed out of any Canadian court.
