YUP, I have done this for quite a few Ottawans, as I used to live on Ottawa, and know the lay of the land. You have 2 transmitter locations: Camp Fortune in Gatineau, and the Rogers Tower in Herbert's Corner in Manotick, and they are far enough apart, and in different directions to require 2 antennas to get everything that is available to you. If you are using only one TV, and are willing to mount outdoors, you can use a single broadband antenna mounted on a rotator, but most Ottawans are loathe to do that because the rotators freeze at times in winter, which locks you into one transmitting location or the other.
The Camp Fortune tower has both VHF and UHF channels on it, however, the Herbert's Corners tower is now all UHF. Since CIII, channel 6 Global, is still on VHF-low band channel 6, you'll need a broadband VHF-UHF antenna aimed at camp Fortune, and a UHF antenna aimed at Herbert's Corner.
I would use an AntennaCraft HD850 mounted on your roof aimed at the Camp Fortune tower, which is located virtually due north of your location. On the same mast, but separated by at least 4', use a UHF Yagi-style antenna like an AntennasCraft MXU-47 aimed at the Rogers Tower, 125 degrees compass heading.
Run a coaxial RG-6u coaxial cable from each antenna to your TV location, and connect each cable to a good-quality RF A/B switch, which will allow you to easily switch from one antenna to the other: remote control A/B switches are available if you don't want to get out of your chair...LOL. You need to be sure to ground the coaxial cable using a coax ground clamp and grounding rod where the cable enters the house to be sure to discharge any static electricity that builds up in the atmosphere and can damage your TV set.
If you plan to run multiple TV sets from this antenna system, there are a couple of extra steps to take, and I will outline them if you need that information. This setup will get you all of the Ottawa-Gatineau stations perfectly: most likely better than you'd see them on cable or satellite.
