I have no personal experience with that tent, but it looks pretty good. I am partial to lighter weight models, but then I typically operate in a dryer environment. You have the really critical item, strong aluminum poles, and what looks like a competently designed shell.
I might suggest checking out the REI Half Dome 2 Plus, which sells for $200 (and even less if you catch it on sale). It is just slightly lighter. I believe it has only one entrance, though. For me that would not be a deal breaker.
I would bet that at some point you will add a light weight solo tent to your inventory or try a bivy sack/tarp combination. The weight savings can be significant. Even then, the tent you are contemplating will still be useful and versatile.
I have never dealt with MEC, but if they are Canada's version of REI, that is good enough for me.
