Cross Border Shipping ( Stallion / Chit Chats) Post May 2nd US Tarriff changes - Slow Down / Stoppage

Does anyone have any info on what exactly is happening at the US border - exports from Canada. The news from Chit Chats is that US Customes is refusing trucks and that Chit Chats is now inspecting every package it is transporting. Absolutely radio silence from Stallion. Anyone got any news?
