[the purge] would Canada and Mexico close borders

Would Canada and Mexico close their borders with the USA, prior to the purge or would they let the Americans seek refuge? Also what would happen to the non-Americans during the purge such as truck drivers?

There would be little reason to close the borders.

Anyone who wants to "purge" can only do it on US soil, so they're not going to leave the USA... and anyone not of that mindset, is welcome in other countries.   The purge is a legal right of any US citizen, so they wouldn't count as refugees.  Instead they would simply be seen as tourists and help feed the Canadian or Mexican economy,  win-win.

Non-Americans (such as truck drivers) during the purge would (or SHOULD) know better than to be in the country during that period.
