HELOC interest for home purchase

Hi, I am wondering under what heading/topic I enter interest paid on my HELOC.

This money was used as a downpayment for a second property, and the transfer of my principal residence into a rental property.  I have a substantial bridge loan interest and then ongoing HELOC interest I'd like to deduct, which the appropriate documentation saying this $ was being used to pay for a property.

I've seen the "line" as directed by the CRA but have no clue what heading that actually goes under in TT>

Thanks
