NeeStaNan project would use port location selected by Canadian government more than 100 years ago
Building a port on Hudson’s Bay to ship natural resources harvested across Western Canada to the world has been a long-held dream of Canadian politicians, starting with Sir Wilfred Laurier.
Since 1931, a small deepwater port has operated at Churchill, Manitoba, primarily shipping grain but more recently expanding handling of critical minerals and fertilizers.
A group of 11 First Nations in Manitoba plans to build an additional industrial terminal nearby at Port Nelson to ship liquefied natural gas (LNG) to Europe and potash to Brazil.

Robyn Lore, a director with project backer NeeStaNan, which is Cree for “all of us,” said it makes more sense to ship Canadian LNG to Europe from an Arctic port than it does to send Canadian natural gas all the way to the U.S. Gulf Coast to be exported as LNG to the same place – which is happening today.
“There is absolutely a business case for sending our LNG directly to European markets rather than sending our natural gas down to the Gulf Coast and having them liquefy it and ship it over,” Lore said. “It’s in Canada’s interest to do this.”
Over 100 years ago, the Port Nelson location at the south end of Hudson’s Bay on the Nelson River was the first to be considered for a Canadian Arctic port.
In 1912, a Port Nelson project was selected to proceed rather than a port at Churchill, about 280 kilometres north.
The Port Nelson site was earmarked by federal government engineers as the most cost-effective location for a terminal to ship Canadian resources overseas.
Construction started but was marred by building challenges due to violent winter storms that beached supply ships and badly damaged the dredge used to deepen the waters around the port.
By 1918, the project was abandoned.
In the 1920s, Prime Minister William Lyon MacKenzie King chose Churchill as the new location for a port on Hudson’s Bay, where it was built and continues to operate today between late July and early November when it is not iced in.
Lore sees using modern technology at Port Nelson including dredging or extending a floating wharf to overcome the challenges that stopped the project from proceeding more than a century ago.

He said natural gas could travel to the terminal through a 1,000-kilometre spur line off TC Energy’s Canadian Mainline by using Manitoba Hydro’s existing right of way.
A second option proposes shipping natural gas through Pembina Pipeline’s Alliance system to Regina, where it could be liquefied and shipped by rail to Port Nelson.
The original rail bed to Port Nelson still exists, and about 150 kilometers of track would have to be laid to reach the proposed site, Lore said.
“Our vision is for a rail line that can handle 150-car trains with loads of 120 tonnes per car running at 80 kilometers per hour. That’s doable on the line from Amery to Port Nelson. It makes the economics work for shippers,” said Lore.
Port Nelson could be used around the year because saltwater ice is easier to break through using modern icebreakers than freshwater ice that impacts Churchill between November and May.
Lore, however, is quick to quell the notion NeeStaNan is competing against the existing port.
“We want our project to proceed on its merits and collaborate with other ports for greater efficiency,” he said.
“It makes sense for Manitoba, and it makes sense for Canada, even more than it did for Laurier more than 100 years ago.”

‘Alberta has never seen this level and volume of load connection requests’
Billions of investment in new data centres is still expected in Alberta despite the province’s electric system operator placing a temporary limit on new large-load grid connections, said Carson Kearl, lead data centre analyst for Enverus Intelligence Research.
Kearl cited NVIDIA CEO Jensen Huang’s estimate from earlier this year that building a one-gigawatt data centre costs between US$60 billion and US$80 billion.
That implies the Alberta Electric System Operator (AESO)’s 1.2 gigawatt temporary limit would still allow for up to C$130 billion of investment.
“It’s got the potential to be extremely impactful to the Alberta power sector and economy,” Kearl said.
Importantly, data centre operators can potentially get around the temporary limit by ‘bringing their own power’ rather than drawing electricity from the existing grid.
In Alberta’s deregulated electricity market – the only one in Canada – large energy consumers like data centres can build the power supply they need by entering project agreements directly with electricity producers.
According to the AESO, there are 30 proposed data centre projects across the province.
The total requested power load for these projects is more than 16 gigawatts, roughly four gigawatts more than Alberta’s demand record in January 2024 during a severe cold snap.
For comparison, Edmonton’s load is around 1.4 gigawatts, the AESO said.
“Alberta has never seen this level and volume of load connection requests,” CEO Aaron Engen said in a statement.
“Because connecting all large loads seeking access would impair grid reliability, we established a limit that preserves system integrity while enabling timely data centre development in Alberta.”
As data centre projects come to the province, so do jobs and other economic benefits.
“You have all of the construction staff associated; electricians, engineers, plumbers, and HVAC people for all the cooling tech that are continuously working on a multi-year time horizon. In the construction phase there’s a lot of spend, and that is just generally good for the ecosystem,” said Kearl.
Investment in local power infrastructure also has long-term job implications for maintenance and upgrades, he said.
“Alberta is a really exciting place when it comes to building data centers,” said Beacon AI CEO Josh Schertzer on a recent ARC Energy Ideas podcast.
“It has really great access to natural gas, it does have some excess grid capacity that can be used in the short term, it’s got a great workforce, and it’s very business-friendly.”

Mines demonstrate significant strides through technological innovation
Tailings are a byproduct of mining operations around the world.
In Alberta’s oil sands, tailings are a fluid mixture of water, sand, silt, clay and residual bitumen generated during the extraction process.
Engineered basins or “tailings ponds” store the material and help oil sands mining projects recycle water, reducing the amount withdrawn from the Athabasca River.
In 2023, 79 per cent of the water used for oil sands mining was recycled, according to the latest data from the Alberta Energy Regulator (AER).
Decades of operations, rising production and federal regulations prohibiting the release of process-affected water have contributed to a significant accumulation of oil sands fluid tailings.
The Mining Association of Canada describes that:
“Like many other industrial processes, the oil sands mining process requires water.
However, while many other types of mines in Canada like copper, nickel, gold, iron ore and diamond mines are allowed to release water (effluent) to an aquatic environment provided that it meets stringent regulatory requirements, there are no such regulations for oil sands mines.
Instead, these mines have had to retain most of the water used in their processes, and significant amounts of accumulated precipitation, since the mines began operating.”
Despite this ongoing challenge, oil sands mining operators have made significant strides in reducing fluid tailings through technological innovation.
This is demonstrated by reductions in “legacy fluid tailings” since 2015.
Legacy Fluid Tailings vs. New Fluid Tailings
As part of implementing the Tailings Management Framework introduced in March 2015, the AER released Directive 085: Fluid Tailings Management for Oil Sands Mining Projects in July 2016.
Directive 085 introduced new criteria for the measurement and closure of “legacy fluid tailings” separate from those applied to “new fluid tailings.”
Legacy fluid tailings are defined as those deposited in storage before January 1, 2015, while new fluid tailings are those deposited in storage after January 1, 2015.
The new rules specified that new fluid tailings must be ready to reclaim ten years after the end of a mine’s life, while legacy fluid tailings must be ready to reclaim by the end of a mine’s life.
Total Oil Sands Legacy Fluid Tailings
Alberta’s oil sands mining sector decreased total legacy fluid tailings by approximately 40 per cent between 2015 and 2024, according to the latest company reporting to the AER.
Total legacy fluid tailings in 2024 were approximately 623 million cubic metres, down from about one billion cubic metres in 2015.
The reductions are led by the sector’s longest-running projects: Suncor Energy’s Base Mine (opened in 1967), Syncrude’s Mildred Lake Mine (opened in 1978), and Syncrude’s Aurora North Mine (opened in 2001). All are now operated by Suncor Energy.
The Horizon Mine, operated by Canadian Natural Resources (opened in 2009) also reports a significant reduction in legacy fluid tailings.
The Muskeg River Mine (opened in 2002) and Jackpine Mine (opened in 2010) had modest changes in legacy fluid tailings over the period. Both are now operated by Canadian Natural Resources.
Imperial Oil’s Kearl Mine (opened in 2013) and Suncor Energy’s Fort Hills Mine (opened in 2018) have no reported legacy fluid tailings.
Suncor Energy Base Mine
Between 2015 and 2024, Suncor Energy’s Base Mine reduced legacy fluid tailings by approximately 98 per cent, from 293 million cubic metres to 6 million cubic metres.
Syncrude Mildred Lake Mine
Between 2015 and 2024, Syncrude’s Mildred Lake Mine reduced legacy fluid tailings by approximately 15 per cent, from 457 million cubic metres to 389 million cubic metres.
Syncrude Aurora North Mine
Between 2015 and 2024, Syncrude’s Aurora North Mine reduced legacy fluid tailings by approximately 25 per cent, from 102 million cubic metres to 77 million cubic metres.
Canadian Natural Resources Horizon Mine
Between 2015 and 2024, Canadian Natural Resources’ Horizon Mine reduced legacy fluid tailings by approximately 36 per cent, from 66 million cubic metres to 42 million cubic metres.
Total Oil Sands Fluid Tailings
Reducing legacy fluid tailings has helped slow the overall growth of fluid tailings across the oil sands sector.
Without efforts to reduce legacy fluid tailings, the total oil sands fluid tailings footprint today would be approximately 1.6 billion cubic metres.
The current fluid tailings volume stands at approximately 1.2 billion cubic metres, up from roughly 1.1 billion in 2015.
