Depends on where the package is coming out from, to where its going... assuming that its coming from a major area in Ontario, it should take 2-3 days to reach Regina. I used xpresspost to ship chaetomorpha from Edmonton to Prince Rupert and it took a couple of days... I believe the chaeto went through the experience still green. Check out
www.canadapost.ca for more info... or talk to the people at your local post office (LPO?
