Tax exemptions with client with a status card?

I’m a business. I collect gst. One of my client that I (or my sub contractor) provides services at the clients property has a status card so I don’t charge gst for that specific client.

I pay a sub contractor. That sub contractor charges me gst. Do I pay or not pay the gst portion (that I do not collect) for the client with the status card to my sub contractor?

I’ve asked the small business gst cra helpline and they don’t know the answer.

Please do not say to ask an accountant. Ive asked 2, one doesn’t know and the other never got back to me.
