re: Renting out property without mortgage holder's consent

The first house I bought I got a 1st time home buyers grant. The grant said I had to live in the home 9 years or pay back the grant(pro rated). Lived in it one year and then started renting it out. Homestead was dropped and the insurance policy was changed to a rental dwelling policy. I paid all payments on time and never heard a word out of anybody about it being rented. The home is now paid for and I have owned it 22 years.
