On my visa (in my passport), there was an expiration date. Try:
http://www.google.com/search?q=Canada+skilled+workers+visa+expirationYes, we also got skilled worker (PR) visas, just like you. Once you get the gray envelope and send in your passports, just check the sticker visa that gets applied. You must land before that date, as far as I am aware.
"I may not have been clear that we are "landing" soon, then moving later."
Ok. Then you are good to go as long as the visa is still valid *when you land*, and you respect the time rule *after you land*. But, I thought on www.britishexpats.com there was some mention of filling out some form when you land, but don't intend to reside there until later (don't quote me on this! :) ).
Unforts, you aren't really eligible for medical until you reside there (BC took 6 weeks to cover us).
When you "land", make sure you go to Service Canada and get your SIN numbers (takes 15 minutes), and open a bank account while you are at it (Coast Capital is a decent CU). While you are at the bank, get a Desjardins Visa (for each of you) and try and get a security backed loan (they put a few thousand into a fund you borrow, you make monthly automatic payments, then after the term, the money is yours--costs next to nothing in interest and boosts your credit rating). You may also want a PO Box, so they have some place to send your PR card in a few weeks.
BTW, any purchases you make with American funds there, well, you may want to get a US Capital One credit card before you leave. They waive the transactions fees and give you air miles. It allows you to do a straight conversion if you pay it off from your US bank account. If you need cash, go to a low-overhead exchanger (if you are in Victoria, try FX Connectors--Ive found no one that beats their rates and the guy there is real nice).
Don't buy a house. BC is a massive bubble. Half a million for a buy in, in the greater Victoria area. Rent out you home in the states for two years, wait out the market, and rent in BC (you need two years of tax returns anyway to get decent rates on mortgages). Be patient. The Liberals have really put BC in a jam, and the economy will go through the shitter and things will readjust
Oh yeah...on the financial stuff....your life just got a little more complicated! Just try and adjust and save some money. :)
I can tell you what we know. We are still learning the ropes too! I definitely love the experience so far and wouldn't change a thing. Im so happy to be able to raise my children here (one was just born here!).
