The deed and the records of how the land was acquired, whether purchase, inheritance or family transfer, plus the mortgage agreement, the lender's advance, and bank statements tracing the money from the loan to the enterprise. The collateral's history is part of the source-of-funds evidence.
Trace the collateral as carefully as the cash
Source-of-funds review looks at where the money came from and, for borrowed capital, at how the investor came to own what secures it. Hypothetical example: the land was bought in the early 2000s partly with savings and partly with a farm loan since repaid, and one parcel came by inheritance from a parent. The file should contain the original purchase agreement and deed, evidence of the earnings that funded the down payment, the old loan and its discharge, the probate or estate documents for the inherited parcel, and property tax records showing continuous ownership.
Then add the current mortgage agreement, the lender's commitment letter, the statement showing the advance, and the wire transfer into the enterprise's account, so that each link is visible. Canadian records in English need no translation; any French document requires a certified English translation. If some early records are lost, explain what happened and provide the best alternative evidence, such as land registry abstracts, rather than leaving a silent gap.
