Section 66

A first mortgagee shall, as between himself and the mortgagor, be entitled to custody of the instruments of title to the mortgaged land so long as any liability under the mortgage subsists, but upon a request by the mortgagor, and upon payment of his proper costs and expenses, the mortgagee shall produce such instruments at the Land Titles Registry to allow the registration of any subsequent mortgage, or of any other authorised dealing by the mortgagor.[62
