I may travel to Canada in the future, but these are the currencies I have:
- Kuwaiti Dinar (1 KD = C$4.50)
- Omani Rial (1 RO = C$3.60)
So, they are worth more in face value. The question is: will money changers in Canada accept or recognize them on directly converting to CAD despite these currencies being uncommon? Also will I really be allowed to bring either 5000 RO (C$18,100) or 2000 KD (C$9,025) in cash?


You could try looking at a currency exchange business.
It could be a longshot because of the currency type, but I go to one every now and again to exchange Pound Sterling.
