Pearson US Immigration office hours

Hi all,

I am going to apply for the TN in Pearson Airport before my flight. However my flight is pretty early at 9 am and I will be at Pearson by 5-6am.

I am wondering if the US Immigration office that processes the TN visas have office hours or if they are 24/7?

Thanks,
Andrew
