(Google Earth is fun!) If the definition is the closest part of the airport, then a much larger part of the city (including the downtown/Beltline and university areas) are off-limits.
If the 9 km rule also pertains to heliports, then virtually the entire city is off-limits; the only residential communities (mostly) over 9km from the airport or a heliport are Bridlewood and Somerset, Rocky Ridge and Nolan Hill; parts of Sage Hill and Tuscany qualify too, as does a portion of the SE industrial area S of 61 Ave, E of 44 St and north of the irrigation canal.

If you have to name a single point which the exclusion zone radiates, it would the airport reference point N51°06'50.00" W114°01'13.00" as described in the Designated Airspace Handbook. That's where our control zone radiates from. It actually isn't 9km distance, but 5 statute miles (we use imperial in aviation). Newspapers usually translate all our imperial measurements into metric. And yes, a helipad is an aerodrome, so are private airports. They are all listed in the Canada Flight Supplement, available at your local pilot supply shop. There are around a dozen in the Calgary region. People also fly from unregistered or abandoned aerodromes.
Drones are a big grey area and frankly I don't want them near any aircraft I am controlling. If a drone is 200 feet above ground (AGL) and below, it shouldn't be an issue, but that all changes directly near airports. At airports there are many more low flying aircraft that just by the runways, lots of helicopters and small aircraft can be in all areas by an airport.
Even not near an airport there are low flying aircraft. We have almost daily pipeline patrols that are only a couple hundred feet above ground, as well as crop/mosquito spraying, forestry operations, fire fighting etc.
