I, a US resident, have a MEC membership and they will ship to me. I believe their online stock does not always match what may be available in their stores, but I am a happy user of their rainpants and overboots.

I'm also looking for shorts to commute in. My commute just jumped a few miles, and it's no longer feasible to ride in my work clothes, plus I've worn out half a wardrobe worth of crotches in the last two years. I'm not normally that rough on clothing. I'm expecting to find some cargo shorts or an equivalent with reinforcements and wear them over lycra I already own.
