I'll update my experience also for those who are searching.
Spouse crossed border with me at vancouver coming from the states. She already had a tourist visa so they just asked to see the marriage certificate. Aside from that they just wanted to make sure we had a quarantine plan. If you dont have quarantine plan, they will ask you more questions. Who will be staying with you, where, how you getting there, how you going to get food and stuff etc. We had a good plan so we were in and out within 2~3 min
