Statscan released the 2008 Canadian Community Health Survey today. A major finding: 91% of Canadians said they were "satisfied or very satisfied with life". Even among those who report a stressful time of it, the number is still 82%.
This, despite (or maybe because !): we're a bit chubby (51%); 21% still smoke (that's down 5 points since '01) and 6.8% say that they've been diagnosed with a mood disorder, (depression, bipolar, mania) - that's a 1.5% increase since '03.
These, and other health indicators, can be found on at the Health in Canada section of the Statscan website.
