Where/how do I enter info from a K-1 (Form 1065)? How do I know what currency the amounts are in? K-1 is from Brookfield Infrastructure Partners L.P. Thx in advance.

You should receive a T5013 (the Canadian equivalent of a K-1) from either from Brookfield directly or your broker. You would then put the T5013 on your Canadian tax return. This page from Brookfield has more information: https://bip.brookfield.com/stock-and-distribution/tax-information
