Forum member @BillHyatt made these suggestions on another thread. Hope this helps:

"Intent to Reside is based on four key factors that OINP looks:

1) How you will benefit more from Ontario as compare to other provinces?

2) What jobs opportunity will you get in Ontario?

3) Your Intent for further studies in Ontario?

4) Health and Government Services you are looking for?

So your answer should cover at least these four areas. For instance saying my Professional network is more established in Ontario as compare to others as most of the relevant businesses are based here. Therefore, it provides more job opportunities and Professional development & growth. Top Ranked universities are based here especially those associated to my field of study. Other benefits provided includes Health and Government services that are easy to access.

Making proper points out of these ideas shall be sufficient to prove your intent even if you don't have any established links in Ontario."
