[The Purge] How do Canada and Mexico spend Purge day?

Given that their biggest neighbor goes fucking crazy for a day, how do these countries react?

I'm thinking a complete lockdown of the borders (no one in or out) and full military presence in the bordering towns, just in case.

Canada is way more affected since its major cities are very close to the border. 

Would they close schools and business for 24 hours? Or the people just don't care and go about their day?

Edit 1: some are saying the USA government wouldn't let anyone leave. How?? Desertion is not a crime during the Purge.

I'd expect every soldier and even more so police officers to just go home to take care of their family instead of guarding the borders.

Likely they'd close the ports for the day and increase security but assuming that US laws keep people inside the borders on purge night more than likely it'd be a minor influx of poorer people fleeing rather than lunatics chasing them into another country.
