Check your local bylaws
The rules regarding antenna towers seem to vary from place to place. However it appears that most areas in Canada now seem to leave it to federal guidelines. Ottawa recently tried to enact a draconian bylaw but was shot down by a big push from Ham radio operators who use the same antenna towers (and more) as OTA enthusiasts. Generally if the tower is less than 15m (49ft) there doesn't seem to be too big an issue in the city and definitely not in urban or rural areas.
Recently I was talking to a friend who wanted to put a single antenna on his roof. He was stopped due to condo rules, yet it seemed he could have put up a satellite dish wherever he wanted. Then he realized that he could even install a 15m antenna tower next to his house and 1.5m from his neighbour. But no antenna on his roof, no can't do that!
Really check your local bylaws and try not to offend your neighbours.

In Ottawa the following are key excerpts. (http://ottawa.ca/en/city-hall/planning-and-development/how-develop-property/policy)
5.1 Residential Use Antenna Systems (RUAS)
The purpose of these guidelines is to encourage the development of RUAS in a manner which mitigates the visual impact on the adjacent property owners.A proponent of an RUAS proposed on a lot less than 1 acre in size should ensure the RUAS:
a) If located within the front yard:
i. Contains only a self-supporting (non-guyed) mast or pole with a diameter no greater than 3 inches at its widest point and used solely for a wire antenna;
ii. is less than 15 metres in height; and,
iii. is set back at least 1.5 metres from all lot lines;
b) If located within a side yard, including the extension of a corner side yard into a rear yard.
i. is set back at least 1.5 metres from all lot lines;
ii. is less than 15 metres in height; and,
iii. does not consist of a guyed or lattice tower, unless the tower abuts and is attached to the principal building;
c) If located within the rear yard, excluding the extension of a corner side yard into a rear yard:
i. is less than 18 metres in height; and,
ii. is set back at least 1.5 metres from all lot lines if less than 16 metres in height; or
iii. is set back an amount equal to a quarter of its height if 16 metres or more in height; and,
d) A wire antenna, not including a tower, need not comply with (a) through (c) above
e) if located on the roof of the principal building:
i. is less than 16 metres in height, and if 15 metres or more in height:
1. is located on that half of the roof closest to the rear yard; and,
2. is setback from all lot lines at least 1.5 metres; or
ii. if the building is greater than 3 storeys in height, the RUAS does not exceed a height equal to 25% of the existing height of the building.
A proponent of an RUAS proposed on a lot at least 1 acre, but less than 5 acres in size should ensure the RUAS:
a) is no higher than an amount equal to the lot width to a maximum of 29 metres;
b) if it includes a guyed or lattice tower, is located outside of the required front yard; and,
c) is set back from all lot lines an amount equal to a quarter of its height;
A proponent of an RUAS proposed on a lot 5 acres or more in size should ensure the RUAS is:
a) no higher than 29 metres; and,
b) setback from all lot lines an amount equal to a quarter of its height;
