ORRI (Overriding Royalty Interest) in Canada

I was wondering what the tax implications are for owning an ORRI in Canada such as if an American would be double taxed with a foreign withholding? Are their added expenses that would lower the yield? Also, could the orri payer alter the current currency that the ORRI is paid in, from a check drawn in cdn dollars to American? Any info on this and any other regulations would be appreciated.

I have lost money to the currency conversion. If we sign again, I would start an account in Canada. Maybe go there for medical stuff and spend the money that way. HA Ha ! Please consider my group for free hold owners in Canada. Lori.
