Bondi Gave a Mortgage to Dante on a Parcel of Land

Bondi gave a mortgage to Dante on a parcel of land (located in Ontario), which he owned. Bondi later sold the mortgaged land to Green. Green, some time later, sold the land to Jones. Jones defaulted on payment of the mortgage. As an alternative, Dante might take action against Bondi, the original mortgagor, on his covenant to pay.
