I've done a comparison below to show some other details of the two cities. Cape Town occupies a larger space and has more people. People in Cape Town are less likely to be able to afford a house than they are in Vancouver.
Summer weather is similar in both cities, although Vancouver has slightly fewer sunlight hours, slightly more rain and a slightly lower temperature. Even though the stats below don't show it, Cape Town really is much warmer than the average of 20 indicates. Daily highs are often in the 30s. Daily highs in Vancouver are mostly in the mid 20s. (Celcius).
The winters are quite different as Vancouver gets much colder and gets a lot more rain than Cape Town (or for that matter, anywhere else in the world!!)
Vancouver is getting ready to host the winter Olimpics in 2010 and Cape Town is getting ready for the Soccer World Cup in 2010.
Vancouver was voted the most liveable city in the world.
According to The International Salary Calculator, the cost of living in Vancouver is 14 % higher than the cost of living in Cape Town.
DISCLAIMER: Please note that most of the data is from 2001. Also, the data has been collected using google, and I cannot vouch for its accuracy. Since the data is from 2001, things like house prices are much lower than they really are today (In both cities)
