4G LTE & 5G Coverage In Ontario

The table below shows the proportion of Ontario with coverage from different cellular technologies.

Network	4G Coverage	5G Coverage
AT&T	100%	100%
T-Mobile	96%	97%
Verizon	100%	96%
Dish	0%	85%

Don't be alarmed by Dish's lack of 4G coverage in Ontario. Dish has a newly-built network that's 5G-only.

US Cellular And Dish Roaming Coverage

US Cellular does not have native coverage in Ontario. However, some US Cellular subscribers may still have coverage in Ontario thanks to roaming agreements.

The 85% figure for Dish may understate what subscribers in Ontario experience after accounting for roaming agreements.

Ontario Cell Signal Strength

There are 1,104 map hexes within the census-defined boundaries of Ontario. The table below shows the proportion of hexes at various levels of signal strength. Where both 4G and 5G coverage is available, data is drawn from whichever technology offers a stronger signal.

Network	Strong	Decent	Weak	None
AT&T	35%	65%	1%	0%
T-Mobile	30%	63%	7%	0%
Verizon	44%	56%	0%	0%
Dish	4%	51%	30%	15%

For most purposes, decent signals are perfectly sufficient. Weak or non-existent signals cause far greater degradation in user experience.
