A new round of Canadian tariffs is now in effect, escalating the trade dispute between the United States and Canada—and raising concerns about the potential impact on Montana businesses, producers and tourism.
Canada's retaliatory tariffs took effect today, September 8.
The tariffs range from 15 to 50 percent and apply to approximately 20 billion dollars worth of American goods.
The action follows new U.S. tariffs on Canadian products, and comes after trade negotiations between the two countries broke down.
Canada's tariffs affect a wide range of American products, including steel, agricultural products, electronics and other manufactured goods.
The new tariffs could be particularly significant for Montana because Canada is the state's largest international trading partner.
Montana exported approximately one billion dollars in goods to Canada in 2025, with Canada accounting for nearly half of Montana's total goods exports.
That makes Canada, by far, Montana's number-one foreign market.
Montana's exports to Canada include agricultural products, livestock, minerals, energy products, machinery and other manufactured goods.
The state's farmers and ranchers could be watching the trade dispute particularly closely.
Montana is a major producer of wheat and beef, while the state also has strong connections to the Canadian energy, mining and transportation industries.
The effects of the trade dispute could also extend beyond products crossing the border.
CANADIAN TOURISM IS ALSO A CONCERN.
Canadian visitors have traditionally been an important source of tourism dollars for Montana.
But travel by Canadians to the United States has fallen sharply during the continuing political and trade tensions between the two countries.
Canadian trips to the United States fell about 25 percent in 2025, according to reports based on Canadian government travel data.
Canadian spending in the United States also declined by billions of dollars as many Canadians chose to vacation within Canada or travel to other countries instead.
The decline has already had an impact in parts of Montana.
In Kalispell, tourism officials estimated Canadian visitation fell by about 38 percent in 2025.
There were signs of improvement this summer, with Canadian traffic increasing in July. But tourism officials expressed concern that the latest round of tariffs and worsening relations between the two countries could slow that recovery.
That could be important for Montana communities that attract Canadian visitors for shopping, recreation, skiing, fishing, hunting and vacations.
Canadian visitors are particularly important to businesses in communities near the border and in western Montana, including hotels, restaurants, retail stores and recreation-related businesses.
The latest trade dispute could also affect cross-border travel in Northeast Montana.
Montana shares more than 500 miles of international border with Canada, and communities along the border have long depended on travel and business moving in both directions.
Even a decline in Canadian visitors coming south for shopping, entertainment or recreation could affect local businesses.
Nationally, Canadian tourism to the United States remained down sharply compared with levels before the trade dispute, although there had been some signs of improvement during the summer.
Tourism industry officials are now concerned the latest escalation in tariffs could discourage more Canadians from crossing the border.
For Montana, the concern is that the effects of the trade dispute could be felt in more than one way.
Farmers and ranchers could face uncertainty in one of their largest foreign markets.
Manufacturers and businesses could face higher costs or reduced sales.
Transportation companies could see changes in the movement of freight.
And Montana's tourism industry could lose Canadian visitors.
The dispute comes at a time when Canada remains Montana's most important international trading partner.
So, for Montana, the relationship with Canada isn't simply about tariffs.
It involves agriculture, energy, transportation, business—and tourism.
And with billions of dollars in goods and significant numbers of travelers moving across Montana's northern border, an extended dispute between the United States and Canada could have consequences on both sides of the border.
