How to write an offer in Canada?

[Leandro Zhao]

Hi BP,

One of my acquaintance who does a lot of wholesaling told me to go knocking on peoples door asking if they would like to sell their property.

My question is how can I write an official offer? Do I need to register my offer here in Ontario, Canada? If yes, where do I go? Is there more source of information of step by step on how to do this in the Canadian market?

Thank you
