The Vancouver community has a JCC, and the dairy restaurant there is called Nava, and is under BCK Orthodox hashgacha. There is an excellent meat restaurant closer to downtown called Maple Grill, also under BCK. THere are a couple of others, including a pizza place, but these two are the best. The community high school, King David, is next to the JCC. There are 2 or 3 Chabad centres, including one downtown down the block from the Holiday Inn, and another chabad affiliated learning centre upstairs from Maple Grill. Congregation Schara Tzedek is the large Orthodox shul, MO mostly, which also has youth programs and NCSY. THe Rabbi is very welcoming, as is the whole congregation. There’s also an orthodox shul in Richmond, I think called Eitz Chaim.
The community is very nice. A couple of things to consider. Beyond the frum community there is a huge amount of assimilation and intermarriage. There is also alot of opportunity for kiruv.
The city itself is magnificent – one of the most beautiful cities in the Western Hemisphere. But for anyone considering living there, be aware that real estate prices – especially in areas where much of the frum community lives – are three times higher than comparable property in other Canadian cities like Toronto, and way, way more than in US cities where real estate has declined in the last 3 years.
