Reais

The Brazilian money is call real (singular) or reais (plurial). Before you leave, make sure to find a good exchange rate. I've called five different currency exchange offices, and for 300$CND some places were offering me only 525 reias, and the best place 600 reais. This last place is called Globex 2000, and has several offices in Montreal. They don't charge fees nor commissions, that's why they offer the best rate.
