Hello
Thought I would offer my input. I have been living in Vancouver with my DH for more than four years. We are both British and came over here on his work permit, we are currently applying for permenant residency (which we could of done ages ago, but just got around to now).
BC coastal climate very similar to UK, rainy wet winters, summers hit and miss though July and Aug are usually great. You can drive inland 4/5 hours for much hotter weather though (Okanagan).
We live downtown and own our apartment, prices are fairly good for a major city, but rising all the time (Vancouver is one of the most expensive cities in Canada for living - the suburbs are better value for buying a house). Eating out is great value and there are fantastic restuarants at every budget.
Amenities are good, lots of libraries, sports clubs, gyms etc. Stanley Park is great for rollerblading, biking, jogging. The local mountains are 20 mins away for snowboarding/skiing and open till 10pm everynight (Dec-April).
We both love living here, but do miss family and friends from the UK - we try to travel back once a year and our families have been here a few times.
We have a mixture of brit ex-pat friends which are great for getting that British humor and gossip fix - as we have a shared 'heritage'. But our Canadian friends are all lovely too, very welcoming and sociable - mostly met through work.
I still read british magazines and we download a lot of british tv off the internet (UKnova).
Shops are a bit crap compared to what you get in the UK no topshop etc, fashion moves slower. But we did just get a H&M so improving.
I would say the average holiday allowance here is 15 days per year, I don't know anyone who gets just 10. We do get a couple more bank holidays than the UK, so we usually plan long weekends around those through the year and then save our holiday up for one long trip in either the summer or the winter (last summer we drove to the Rockies and this year my family is joining us for skiing in Big White resort).
Flights back to the UK are ok, but expensive to do often. Vancouver is a great base for exploring North America, Seattle is 2 hours drive, San Fran 2 hours flight, LA same, Las Vegas 2 and a half. But to get to the east coast (NYC etc.) it is nearly as much as flying home (cost and distance wise).
I don't know much about the childcare system here yet(first is due in Sept), most women take maternity leave for a year, then go back fulltime or to jobshare.
BC is really a beautiful place to live, and does offer a great lifestyle and I recommend moving here to anyone. I would just say do your reseach about which area you want to live and keep an open mind when you get here (takes awhile to make friends and feel settled). Good luck with your planning. Feel free to ask any questions.
