Canada and the United States share one of the world’s most integrated energy relationships, but many people are surprised to learn just how important Canadian electricity exports are to the American power grid. While Canada is widely known for exporting oil and natural gas, electricity exports from Canada to the U.S. have quietly become a major part of North America’s energy system.
The question many Canadians are now asking is simple: Why does the U.S. buy electricity from Canada? And if electricity exports decline because of trade disputes, tariffs, or changing energy policies, what could happen to electricity rates in Canada?
The answers reveal a complex relationship involving affordability, hydropower, energy security, and billions of dollars in cross-border trade.
Why Does the U.S. Buy Electricity From Canada?
The U.S. buys electricity from Canada because Canadian power is often reliable, affordable, and available exactly when American states need it most.
Unlike many imported products, electricity cannot simply be ordered from another continent. Power grids must remain connected in real time, meaning neighboring countries become natural trading partners.
Canada has enormous hydroelectric resources that generate clean electricity at relatively low costs. Provinces such as Quebec, Manitoba, and British Columbia produce large amounts of surplus hydropower that can be exported south of the border.
American utilities purchase this electricity because it helps stabilize local grids and often costs less than building additional generation capacity.
The U.S. electricity grid and Canadian electricity grid are deeply interconnected through dozens of transmission lines crossing the border.
When demand spikes in places such as New York, New England, Minnesota, Michigan, or parts of the Pacific Northwest, Canadian electricity can help meet those needs quickly and efficiently.
This is one reason why electricity exports remain an important part of Canada’s economy.
How Much of U.S. Electricity Comes From Canada?
Many people assume America depends heavily on Canadian electricity. In reality, the percentage is relatively small on a national scale.
Only about 1% to 2% of total U.S. electricity consumption comes from Canada. However, Canada supplies the vast majority of imported electricity entering the United States.
While the national percentage appears small, Canadian electricity plays an outsized role in certain regions.
New England and New York
New England and New York frequently rely on Canadian hydropower, especially during winter demand peaks.
At certain times, imported electricity from Canada has supplied significant portions of regional power demand. During periods of extreme weather or high consumption, these imports become especially valuable.
The Upper Midwest
States including Michigan and Minnesota receive contracted electricity from Manitoba.
These long-term agreements provide stable electricity supplies and help utilities manage costs.
Pacific Northwest and California
Hydroelectric power from British Columbia contributes to balancing electricity systems throughout the western United States.
When renewable generation fluctuates, Canadian hydropower can help fill the gap.
This regional importance explains why electricity imports from Canada remain strategically valuable even though they represent a small share of total U.S. electricity use.
What Happens If Canada Exports Less Electricity?
Many Canadians assume that reducing electricity exports would automatically lower domestic electricity bills.
The reality is often the opposite.
Electricity exports generate billions of dollars in revenue for provincial utilities. Those revenues help support infrastructure investments, maintenance costs, and public energy programs.
If exports decline significantly, utilities may lose an important revenue source.
That could create pressure to recover costs elsewhere, potentially resulting in higher electricity rates for domestic customers.
This is why energy experts often describe electricity exports as beneficial not only for American buyers but also for Canadian consumers.
A reduction in exports could mean lower revenues at home, fewer opportunities to spread fixed costs, and potentially higher electricity prices for residents.
Which Province Has the Cheapest Electricity in Canada?
When discussing electricity costs, one province consistently ranks at the top for affordability.
Quebec Has the Cheapest Electricity in Canada
Quebec enjoys some of the lowest residential electricity rates in North America thanks to the massive hydroelectric network operated by Hydro-Québec.
The province’s extensive hydroelectric dams generate enormous amounts of low-cost renewable power.
As a result, Quebec residents generally pay some of the lowest electricity rates in Canada, often around 7 to 8 cents per kilowatt-hour.
This affordability has helped attract businesses, manufacturers, and data centers seeking access to inexpensive electricity.
Provincial Electricity Rate Rankings
Electricity costs vary dramatically across Canada because each province uses different energy sources, regulatory systems, and utility structures.
Lowest Electricity Rates
- Quebec – Approximately 7.8 cents per kWh
- Manitoba – Approximately 10.2 to 10.6 cents per kWh
- British Columbia – Approximately 11.4 cents per kWh
- New Brunswick – Approximately 13.9 cents per kWh
- Ontario – Approximately 14.1 cents per kWh
Higher Electricity Rates
- Newfoundland and Labrador – Approximately 14.8 cents per kWh
- Nova Scotia – Approximately 18.3 cents per kWh
- Prince Edward Island – Approximately 18.4 cents per kWh
- Yukon – Approximately 18.7 cents per kWh
- Saskatchewan – Approximately 19.9 cents per kWh
- Alberta – Approximately 25.8 cents per kWh
Most Expensive Electricity
The highest electricity prices are generally found in Canada’s northern territories.
Nunavut and Northwest Territories face unique challenges because many communities are not connected to major continental power grids and rely heavily on diesel generation.
Transportation costs, fuel expenses, and remote infrastructure requirements significantly increase electricity prices.
Why Hydropower Gives Canada an Advantage
Canada possesses one of the world’s largest hydroelectric systems.
Hydropower offers several major benefits:
- Low operating costs after dams are built
- Minimal fuel expenses
- Reliable electricity generation
- Reduced greenhouse gas emissions
- Large export potential
Provinces such as Quebec, Manitoba, and British Columbia have leveraged these advantages to become major electricity exporters.
Their abundant hydropower resources make Canada one of the world’s leading clean electricity producers.
Why U.S. Demand for Canadian Electricity Will Likely Continue
Despite political debates and occasional trade tensions, most energy analysts expect the United States to continue purchasing Canadian electricity.
Growing electricity demand from artificial intelligence, electric vehicles, manufacturing expansion, and data centers is increasing pressure on American power systems.
At the same time, Canadian hydropower remains a reliable source of low-carbon electricity.
That combination makes cross-border electricity trade attractive for both countries.
For the United States, Canadian electricity helps maintain grid reliability and affordability.
For Canada, electricity exports create valuable revenue, support provincial utilities, and strengthen economic ties with America’s largest trading partner.
The Bottom Line
The U.S. buys electricity from Canada because Canadian power is affordable, reliable, and readily available through an interconnected North American grid. Although only about 1% to 2% of total U.S. electricity consumption comes from Canada, those imports play a critical role in regions such as New York, New England, the Midwest, and the Pacific Northwest.
At the same time, electricity exports benefit Canada by generating revenue that helps support provincial utilities and infrastructure investments. Contrary to what many people assume, lower electricity exports would not necessarily lead to cheaper Canadian power bills. In some cases, reduced export revenue could actually place upward pressure on domestic electricity rates.
Meanwhile, Quebec continues to hold the title for the cheapest electricity in Canada, thanks to its vast hydroelectric resources, while northern territories such as Nunavut and the Northwest Territories face some of the highest electricity costs in the country.
As energy demand continues rising on both sides of the border, Canadian electricity exports are expected to remain a key part of the North American energy landscape for years to come.
