Philly one of the trickiest and most provincial places I've ever witnessed.

Technically, the difference is that owner-occupied properties receive a rebate of the provincial portion of the property taxes assessed and only pay the municipal portion.

They must register with the Canadian government (federal, not provincial) and setup with an account number.* Every month they collect the rent for you. 

I live near Boston and would be interested in hearing some provincial local advice.

They (the provincial govt) had a plan for payment of back rent starting in Oct.

I know where some of my rentals are, we have a check list from the provincial government and it actually lists having the carpets professionally cleaned as one of the things the tenants have to do when they move out.

Everyone is pretty bang on here, but I would make sure that you have and air tight lease/rental agreement.Also, know and your local and state/ provincial tenancy laws and by laws.  

As a land surveyor I am constantly working with local municipal governments (the list is many and varied) and provincial government on projects.

For the most part, privacy law does no permit trade in such information.Depending upon the province, you will need to consult the local municipality or the provincial land registry to find the owners of a property.  

Or Is there any specific law regarding this from the provincial/federal govt.?
