Those STRONG local transmissions will prevent the use of a antenna amplifier and the stations that are far away are Very Weak and the low power stations that are close are Very Weak.
You could install a Winegard HD7084P antenna with No amplifier or a HD7698P antenna with No amplifier and something I seldom recommend (antenna rotor) and aim the big antenna at the Weak stations at favorable TV DX times and receive those Weak stations.
The HBU33 is good , it is not all that directional and has some forward gain and receives channels 7 thru 69.
May I suggest a Winegard HD7000R , it is not all that directional and has some forward gain and receives channels 2 thru 69.
The reason I suggest the HD7000R is , tvfool is not up to date on channel assignments of Canada , however tvfool does show Analog channels 4 and 6 being transmitted.
Anyway the aiming direction for reception at your location is about 140 degree magnetic compass.
Here is how to aim antennas ,

http://www.antennacraft.net ,
http://www.3starinc.com , some Canadians buy from the States and have it shipped to relatives or friends close to the border on the USA side. .
The satellite mount can be used for the HBU44 , HBU33 or HD7000R , mounting antennas above the high point of a roof is usually the best for reception.
I do not recommend the satellite mount for big antennas like the HD7084P or HD7698P.
Here are some Strong and Sturdy antenna mounts that will work with any antenna.
