Have you bothered to read through some of the older threads here? Verse and Chapter for this question get quoted on a regular basis.
There is no snow bird visa.
There is no retiree visa.
There is no homeowner visa.
Canadians can legally enter for 90 days or apply for a 180 day visitor visa. Be sure to have proof of binding ties to Canada and intentions of returning there. The option to extend this to 360 days while in the US does exist. None of these guarantee your stay up to the maximum amount of days. This is within the discretion of the immigration officer at point of entry. You will run into a problem with your medical insurance and potentially with taxes depending on the length of your US stay. Homework!
