I read through this entire thread and found it very interesting....very insightful.
Make sure you are upfront with service Ontario regarding your absence and your need to start the 3 month waiting period again. Much betrer to be upfront then to risk getting caught and being charged with fraud. Many people are unaware of the 3 month wait period and that it also applies to citizens that have been living out of the country. Many people arrive right before their due date so you are lucky because you will have coverage for the end of your wife's pregnancy and delivery.
