How water filtration in Vancouver, Canada differs from the one in Tehran, Iran?

I will emmigrate to Canada,legally.I have the choice between Toronto,Vancouver and Calgary,wich one to choose?

• I learned that all three cities are wonderful places to live in and that is why I have a decision very difficult to made.I shall appreciate any help. Until now I have only visited Toronto myself,Calgary and Vancouver I only know them from books,tv and internet. Toronto has the advantage of being the so called "capital" of canada finance and industry so jobs are quite easy to get. Calgary is in economic boom due to its natural gas reserves so jobs are even easyer to get.Vancouver on the other hand was quoted as best city to live in by the UN. Tough decision to get,huh?!:-)

• Answer:

  The majority of immigrants to Canada choose to settle in Toronto. It may be beause they don't know of any other cities (my experience in the Middle East was this was often the case). We are fortunate in that there are many wonderful places to live in Canada, whether small rural towns or large, metropolitan cities. You can choose from either coast, to vast prairies, to our nation's capital, Ottawa. If your English skills are good, you might be comfortable in most places. If not, you may want to settle near a community from your home country. I would suggest that you think about the following issues: 1. do you want to settle with others from your home country 2. what kind of work do you intend to seek? Different industries are concentrated in different parts of the world? 3. do you want the urban life, or a more rural existence? 4. what kind of climate are you searching for? - these three cities are each quite different - Vancouver is most temperate, with a great deal of rain. Calgary has great sumemrs and harsh winters. Toronto has wet, cold, miserable winters and humid summers. At the risk of causing a firestorm, I would suggest that, stereotypically, Calgary has a reputation for intolerance with respect to different races. This might be unfair, however, since Alberta apparently offers more "second language" options than any other province. Perhaps of all the factors, your employment prospects are the most important. Without a solid employment situation, you will find it much more difficult to enjoy your new-found home.
