Canada’s nuclear energy industry is experiencing a significant revival after a prolonged slump that led to widespread job losses and operational shutdowns. This resurgence is driven by renewed global interest in nuclear power, positioning the country’s uranium mining and reactor sectors for expansion.
At the heart of this revival is Saskatoon-based Cameco, one of the world’s leading uranium producers. Following a decade marked by challenges, including halted production at several key sites, Cameco has restarted operations at its McArthur River and Key Lake facilities. Plans are underway to open a new section of the Cigar Lake mine in 2030, although production remains suspended at the Rabbit Lake mine. The resurgence comes amid heightened demand for uranium as countries worldwide invest in nuclear energy to meet growing electricity needs.
Canada’s federal government has outlined an ambitious vision to expand its nuclear capacity, proposing the construction of 10 new reactors by 2040. This includes Ontario’s development of a small modular reactor at the Darlington station and Saskatchewan’s plans for a similar small reactor in the coming decade. Ottawa also aims to increase uranium exports and promote Canadian-made reactors internationally.
The nuclear industry’s recent upswing contrasts sharply with the fallout from the 2011 Fukushima disaster in Japan, which triggered a sharp decline in uranium prices and dampened public support for nuclear energy globally. That crisis led to shutdowns, layoffs, and financial hardship for many workers in Canada’s mining sector, with some forced to sell homes at a loss and uncertain about the industry’s future.
Despite these setbacks, industry leaders emphasize the ongoing demand for nuclear power as a stable, low-carbon energy source. The renewed investment in reactors and uranium extraction reflects growing recognition that nuclear energy plays a key role in meeting the world’s escalating power requirements.
If sustained, this nuclear renaissance could bolster Canada’s position as a major player in the global nuclear market while providing economic benefits for mining communities long affected by industry volatility.
