Spiderdan I know that road like the back of my hand as it's on my commute home and probably only five minutes to my house.
The slippery when wet sign right at the base of the cliffs indicates 30km/h; the twisties ahead sign right before it is my cue to drop down from fourth to third and hammer on the gas to get that sweet sound of exhaust resonating off the cliff and go up the bends.

Most of the time I hang back from traffic ahead and put some distance between us so I can plant the throttle for a few moments.

It's fun on the way down, too, (exhaust is even closer to the cliffs!) but physics are against you should there be an "incident" and you wouldn't scrub off speed in the same way as if you are going uphill.
If people are wondering what it's about, here it is:

It's actually much more elevated than it looks.
Dan, I think you're right on the money re the officer's duties. While there are sometimes traffic enforcement RCMP on the road (you can tell them by their radar mounts and/or light strip on the inside of the back window) most of the RCMP that you'd see around there are on embassy, Prime Minister, or Governor General detail. They use the parkway a lot because the Protective Services campus as at the end of the parkway in Gloucester (St. Joseph Blvd) so often they're on their way to their assignment. Last year I had the same kind of treatment: I didn't get the lights, but an officer pulled up beside me at a stop outside of the GG's Princess Ave. gate and we had a chat about speed.
Ottawa's a funny place in terms of law enforcement. We have the RCMP (national force) for dignitaries, embassies, and federal properties and NCC roads; OPP (provincial) for 400 series highways, outlying areas, and will assist in water rescues; and finally, the Ottawa Police as our local municipal force for everything else. Pop over one of the bridges spanning the Ottawa River and then you add in the Sûreté du Québec as you've crossed into another province. Ah, the joys of the capital.
Unusually warm weather over the next few days, so I think another week of Spider weather. Yay!!
