Pro IFR Vancouver
In a word, pretty good. They have two divisions to the school - Pro IFR and Pro VFR, but are mainly specialists in IFR. They fly the Duchess, which is a very simple and solid IFR twin trainer and their "IFR training system" as they like to call it is very well put together. Don't expect to stay with one instructor only though (a notion which I found a bit odd coming from smaller schools) - you will find you may be with three or four different ones throughout your training depending on who is available on what day.
They operate out of Boundary Bay, 18 miles south of Vancouver. Its a busy training airport, pretty well located and itself has a VOR approach only. All your training will be done at Abbotsford, about 20 miles away, but the initial approach fix is only about ten miles away at White Rock NDB. Flight test is normally with their in house DFTE, who is also the owner.
Pro are certainly not the cheapest on the field, but as I said the equipment and availability is normally good so if you can afford it, go for it.
