However while people in Windsor doesn't have the luxury of high paying jobs that GTA residents have, is it just a temporary fever of buying houses, or there is really something going on in this city ? 

Nice job! 

Throughout the year I come across situations where people need to sell there home due to a variety or reasons, job loss, income loss, health, divorce, etc.

If you need a new job once you move, you will need an offer letter prior to closing on your new home (and you will need 6 months reserves in order to be able to use the offer letter as income). 

Looking for ways to expand my network as well as possible job opportunities. 

In Columbus, you can still find the 1% rule and there's amazing appreciation potential due to how much population growth, job growth, and companies moving/developing there (recently Anduril just announced another 4,000 jobs coming to Columbus Ohio on top of Intel, Google, Amazon, FB, Nationwide, Ohio State University, etc.).

Not to mention the economic development steps the town is taking in ensuring the growth of town (roads, schools, zoning) stays on par with the future expected population growth and new jobs that are going to be a result of the new factories opening.  

With people continually migrating from CA, more jobs moving here (Tesla Semitruck factory being built as I type this), I don't know how this gets solved. 

The markets open up if you are not planning on doing the management yourself.There are many markets that are growing in population and jobs throughout the country if you are willing to look at OOS investing. 

Currently work a day job and have no capital to start off with.
