I haven't bought any of MEC's recent offerings for cycling, but MEC has an unusually cycling-savvy selection of gear. I bought their Bernoulli cycling jacket quite a long time ago and still feel it is one of the best cycling rain jackets I ever bought (though heavy, but the polyester shell fabric sheds water much better than nylon). When you see a company that incorporates lots of venting options in their cycling clothes then you know that they do a lot of cycling themselves.
You may want to check out Burley Designs, a US-based cycling cooperative (Eugene, Oregon... where people really know their rain) that makes some of the best cycling rain gear around. They've been making their rainwear since the early 80's, when their rain jackets were the standard for touring in the rain.
MontBell makes some very nice cycling rain gear, but I'm not sure if they sell them in the States. My one complaint about their cycling rain gear is that they have few venting options. During all my years of cycling touring I have never been comfortable with cycling rain gear that doesn't breathe well, especially when slogging up those mountain roads when it's pouring. Even today I still use my Bernoulli for long tours. It may be heavy, but it really works.
