I write this for journalists, first year economics students, and the general (non-economist) public. Yes I'm being pedantic. But I hope it helps. I'm trying to clear up a very common confusion in how we talk about inflation.
Your car has an odometer, which measures kilometers driven. And your car has a speedometer, which measures kilometers per hour.
The CPI price level is like the odometer. It tells you how high the price level is (compared to some arbitrary base year, which is set at 100 for convenience).
The CPI inflation rate is like the speedometer. It tells you how quickly the price level is rising (usually per year).
[OK, assume your car is a vertical rocket ship, or at least pointing uphill, if that helps. And the CPI is just the price of a basket of goods, so it averages out the prices of the individual goods.]
The only difference is that Statistics Canada only checks the odometer once a month. And the speedometer (usually) measures how many kilometers traveled per year, compared to the same month last year (so they don't have to worry about seasonal adjustment). And the speedometer can record a negative speed, which means the car is going in reverse and the odometer is going backwards (remember Ferris Bueller?)
If you say "the Consumer Price Index (CPI) rose by 1.2% in November, compared to 0.9% in October and 1% in September" that actually means something quite different from what you probably think it means or meant to say. [That's an actual quote from a UK newspaper, except I have substituted the actual 1.2% for the 1.1% economists had predicted.]
