I've been to china and have spent a lot of time there both studying and working and the first thing you experience in China is the diversity. There's a small part of the Chinese population that would actually consider hell money as apart of their culture.
User "stupandaus" had a good point about the different waves of Chinese immigration to US/Canada which included different ethnicity and even language that would give a reason why hell money isn't seen in some areas.
Based on the responses in this thread, it seems to be more prevalent in areas with Cantonese populations.
The tradition reminds me of the Egyptian rulers who were buried with everything they might need on the other side.
