We are also from Canada but now we travel the other way.... from Belize to Canada (West Coast) return. We found flights from Belize City to Vancouver round trip for 2 for less than $1500 total. That is American Airlines. We just kept checking until we found reasonable prices. However, if you are coming from the west coast, there is no way you can make it in less than a full day. Now if you are from Alberta, I would suggest you try out of Calgary - cheaper than from Edmonton and you can find 7 - 8 hour flights. I hope this helps, if you need more information, PM me.
