Your wife still has her status as a PR. There is nothing to re-instate. Her being approved for the PRTD is one fact that she is still a PR.
The other member posted about requirement for provincial healthcare coverage.
It's different in each province.
To be eligible for Ontario health insurance coverage, generally speaking a person must:
- have Canadian Citizenship or other immigration status as listed in the regulation
- make his/her primary place of residence in Ontario; and
- be physically present in Ontario for 153 days in any given 12-month period
In addition, most new and returning applicants for OHIP coverage must also be physically present in Ontario for at least 153 of the first 183 days after establishing residence in the province (exceptions are noted in Regulation 552).
