I have contacted the CBP-Blaine WA ,CBP-Edmonton, AB, CBP-Calgary, AB today and learned that they are still waiting for proper directions and details from the DHS on essential travels. Now that the airports are shutting down, they have advised me to go to the nearest border, which is Montana SG - POE for me and attempt to get the TN renewed. I have tried to the reach out to the CBP Montana but with no luck. I am taking a chance by driving tomorrow to the border to get my TN renewed with all the necessary documentation and drive back to Canada. If you think my idea is bad then please caution me.
