Hi, thank you for using TurboTax AnswerXchange
AgriStability and AgriInvest Programs report income on a form T1163 or T1273 depending on the province the farm is located. There is a detailed discussion of reporting income and expenses available at the Canada Revenue Agency (CRA) at the following link:

Generally a partnership reports the total income minus expenses for the farm/business and the resulting net income is split and reported by each partner based on their percentage ownership. The above link has discussions for partnerships. Farms in a partnership maybe reported on a T5013 slip based on rules set by CRA :

Hope this helps
