Moving to Saskatchewan
If you and your family are moving to Saskatchewan at the same time, you will have Saskatchewan health coverage beginning on the first day of the third month following the date you established residency in Saskatchewan. Normally, your home province will cover you and your family until your Saskatchewan benefits take effect.
For example, if you established residency in Saskatchewan September 27, then your Saskatchewan health coverage would begin December 1.
Married/Common-Law Couples Moving on Different Dates
If you move to Saskatchewan, and your spouse will be joining you within 12 months of your arrival, then you will both have Saskatchewan health coverage starting on the first day of the third month following the arrival of your spouse in the province.
For example, if you arrive in Saskatchewan on January 1 and your spouse arrives on June 10, then you will both have Saskatchewan health coverage beginning September 1.
If your spouse does not join you within 12 months of your arrival, then you will each be considered individually. You will have Saskatchewan health coverage beginning at the end of the 12-month period and your spouse will have coverage beginning on the first day of the third month following his or her arrival.
For example, if you arrive in Saskatchewan on January 1, 2017 and your spouse joins you in June 2018, then your Saskatchewan health coverage begins January 1, 2018 (at the end of the 12-month period), and your spouse's coverage begins September 1, 2018.
In both situations, your former province of residence will continue to cover you while you are in Saskatchewan, until your Saskatchewan coverage takes effect.
