Is there any easy way to know if you suffer vitamin D defeciency? I'm in Vancouver, and especially at this time of year you end up inside for pretty much all the daylight hours Monday-Friday.

It's diagnosed through a blood test. As far as I know, you can't really diagnose it accurately in any other way. But in developed countries the rule of thumb on that is:
Do you work outside in the sun? Do you eat a lot of fish? Do you take a vitamin D supplement? If you answered "no" to all of these questions then you probably have a vitamin D deficiency. Vitamin D deficiency is very common.

Vitamin D deficiency was defined as a serum 25-hydroxyvitamin D concentrations ≤20 ng/mL (50 nmol/L). The overall prevalence rate of vitamin D deficiency was 41.6%, with the highest rate seen in blacks (82.1%), followed by Hispanics (69.2%).
