                           Calgary neurologist Dr. Serena Orr injecting a patient to help treat migraines.  Researchers in Calgary are spotlighting a promising treatment for people living with severe migraines: occipital nerve blocks . This approach involves injecting a small amount of anesthetic near the occipital nerves at the back of the head, which can interrupt pain signals and provide rapid relief. Neurologist Dr. Serena Orr of the University of Calgary has been at the forefront of this research, recommending updates to the American Headache Society’s guidelines for emergency departments.

ICE Confirms Roshel Armoured Vehicles Built in U.S. Under Buy American Rules

 

The emblem of a Roshel armoured vehicle is seen at the Canadian Association of Defence and Security Industries annual defence industry trade show CANSEC in Ottawa on Wednesday, May 28, 2025. 


U.S. Immigration and Customs Enforcement (ICE) has clarified that the fleet of armoured vehicles it recently ordered from Canadian defence manufacturer Roshel will be produced in the United States, ensuring compliance with Buy American provisions.

ICE is sole-sourcing 20 Roshel Senator emergency response tactical vehicles in a contract worth approximately $10 million CAD. The agency stated that while Roshel is headquartered in Brampton, Ontario, the production of these vehicles originates in the U.S., allowing the procurement to meet domestic manufacturing requirements.

The vehicles, designed to withstand bomb blasts and heavy gunfire, are intended to support ICE agents in high-risk field operations. Similar Roshel Senator models have previously been deployed internationally, including in Ukraine’s defence efforts against Russian aggression.

Despite repeated requests, ICE has not provided a named spokesperson for the announcement, and Roshel itself has not commented publicly on the matter. The procurement has drawn criticism from some advocacy groups concerned about the militarization of immigration enforcement, while others highlight the urgency of equipping agents with advanced protective technology.

This purchase underscores the growing role of Canadian defence firms in U.S. security operations, while also reflecting the complex balance between international partnerships and domestic production rules.
