Traveling to Cuba... from Canada?

I will traveling to Cuba for a one week vacation this coming weekend. I have a question in regards of the below of what my travel agency has sent me my ticket, which states:

"Cuba immigrants required a minimum of spending money of 50 CUC/PESO/DAY to holiday in Cuba. Failure to do so could cause refusal of entry"

What does that mean? Does that I mean I require to bring in 50CUC/PESO/DAY in cash? or I will be refused to enter??? or it means that how much I spent in my cuba vacay should be 50 cuc or more????????

So basically u need a minimum of 350Peso because your staying there for 7 days. It means that u gotta spend 50Peso per day from the information u gave me.

hallo,
you have to bring along the document which will prove that you've got sufficient funds required for your trip to Cuba. it doesn't mean you must bring money in cash.
