I have rental property in the US co-own with me brother (US citizen). Field for a SIN which my brother doesn't have. 9 0's failed with Rev-QC filing. Suggestions?

You would enter your share of the foreign rental income on "Foreign Income" slip, as "Other Income (line 130)" along with any foreign taxes paid in the field next to "Other Income". 

Rental income forms (T776 and TP-128) are used to report Candian rental income.
