For your reception situation , 1 antenna will do it all.
A Channel Master CM4228HD UHF/VHF antenna will receive the local Canada Digital Tv stations/channels.
The local channels are -->Very Strong Signal Strength<-- and the CM4228HD UHF/VHF antenna will receive the local Digital Tv stations/channels at the front and back of the CM4228HD UHF/VHF antenna because the local Digital Tv stations/channels are Very Strong Signal Strength.
No preamplifier or distribution amplifier is required for reception of the local Digital Tv stations channels.
Aim the CM4228HD UHF/VHF antenna at about 150 degree magnetic compass direction.
Here is how to aim antennas ,

A Tv antenna rotator is not required.
________________________________________
For 1 Tv connected use No splitter.
For 2 Tv's connected use a simple common 2 way splitter.
For 3 Tv's connected use a simple common 3 way splitter.
______________________________________________________________
For reception of some USA Digital Tv stations/channels.
The Same<->Channel Master CM4228HD aimed the same direction at about 150 magnetic compass direction.
150 degree is a in between aim direction for reception of the USA Digital Tv station/channels.
As always , the starting antenna aim direction is the --> starting antenna aim direction.
The antenna aim direction can be adjusted to provide the best reception.
Most Digital Tv's have a signal strength meter and some Digital Tv's also have a signal quality meter.

The Canada Digital Tv stations/channels are Very Strong Signal Strength , so a amplifier that has high resistance to being overloaded is required for reception of the USA Digital Tv stations/channels that are Very Weak Signal Strength.
Install a Winegard 'Boost' amplifier , LNA-100.
The LNA-100 is not weather/water resistant , so the LNA-100 is installed at a location that is out of the weather/water.
The LNA-100 is installed before the input side of the splitter.
The best practice is to install the amplifier closer to the antenna , to get the most and strongest signal from the antenna before any signal strength losses through long lengths of coax.
Reliable reception of the USA Digital Tv stations is the goal.
