Hi Folks,
This one is good! I can't find squat on much of any of this...nor can I find anyone who can answers.
Please advise and thanks!
My mother is:
1. Canadian citizen by birth, lived there for 30 years
2. US Resident Alien for 27'ish years BUT
3. Recently became a naturalized US citizen
4. No spouse; no kids that she's trucking around with her.
Just her.
Situation:
1. She has elderly parents in Canada that require her assistance when she's available (more time may be needed going forward)
2. She lives in the US
3. She owns property in Canada
5. Prior to the last few years (while a US green card'er), she spent all but 2 weeks only outside of the US, the rest at her US home
4. Prior to her US naturalization and for the last few years only, she spent the minimum in the US allowed by law b/c of the aging parents.
5. She is retired, holds no job in either country, has no plans/need to, and lives on her private savings that were earned in the US prior to retirement.
6. Files a US tax return; no Canadian.
Questions:
1. What does she need to fill out to consummate on the Canadian side that she is a dual citizen of Canada & USA?
2. Where should she claim permanent residency? Does one benefit the other? Or allow for more relaxed travel between the US and Canada?
3. Does she need to spend 6 months + 1 day in one of the two countries?
4. She pays US medical insurance but coverage in Canada on that policy is horrible. Can she qualify for Canada Medicare / MSI (in Nova Scotia) while in Canada? If so, how and what does she need to give up on the US side, etc.?Because most of my reading says you can't be a PR of Canada (to get CAN Medicare while in CAN) but a PR of US also.
5. If she spends 6 months + 1 day in Canada (without *official* Canadian PR), does she need to file a Canadian tax return? Remember, she is retired and earns no wages in Canada.
6. In general, what would you do if you were US naturalized & PR, Canadian by birth, need to spend a majority in Canada to assist parents for now, and might spend more than 6 months in US one year and more than 6 months in Canada the next, etc.
7. How long can a Canadian PR spend in the US consecutively? How long in a the US over a given time period (i.e. 6 mos PER CALENDAR YEAR)?
8. Why is it sooo hard to get these answers elsewhere....and the answers not be conflicting among sources...uuurg.
She wants to do the right thing but it's so difficult to figure out what the right thing is. 
If all of these questions can be answered here, who in the world should she ask?!
Thanks folks! Sorry this one didn't really fit into a single forum category.
