There are a number of different scenarios that could present themselves. Generally speaking, if travelling Canadians find themselves in trouble in a foreign country, there are United Nations conventions that would engage the consular services of Global Affairs. I won't speak in any detail about their engagement and how they do it and why they do it. That's what they do.
In terms of INTERPOL, I don't know specifically that people who are travelling, who find themselves in trouble, would reach out to it at all. It's not what it is for. INTERPOL is a platform for police to share intelligence and evidence of criminal investigations.
