The usual YMMV caveat applies, but... just in case anyone in Canada is nervous about ordering from RA with border "stuff" going on... I rolled the dice and ordered some parts a few days ago (about $120usd). Had it shipped FedEx (just in case UPS is different). What I was charged up front (~$41) on the RA site is ALL I paid. No further tariffs etc. Whew!
Anyhow, just thought people up here would want to know.
