Yes.  You are entitled to both credits.  According to CRA:

You can claim this amount if the rules are met for claiming the amount on line 369 of federal Schedule 1.

You can claim an amount of $10,000 for the purchase of a qualifying home.  A qualifying home must be registered in your and/or your spouse's or common-law partner's name with the Land Titles Registry and must be located in Saskatchewan.

The claim can be split between you and your spouse or common-law partner, but the combined total cannot be more than $10,000.

When more than one individual is entitled to the amount (for example, when two people jointly buy a home), the total of all amounts claimed cannot be more than $10,000.
