Well, it's not like he's a professor of food with a claimed expertise in food supply chains. Go easy on him.

Now this looks useful for the Canadian climate policy modelling community, an analysis by @aleach.ca of what is actually legally allowable under Canada’s constitution … @naviusresearch.bsky.social @climateinstitute.bsky.social

My hope: Lewis wins the leadership, reduces the NDP to a single seat that isn't his, and I get to watch Shannon laughing exactly like this on an election night panel. If your NDP doesn't include people like Shannon, you're not going to get very far.

From last night. Don't let anyone convince you that "we export crude and import the refined products back to Canada." that's not how it works.

Andrew Leach @aleach.ca · 03/02/2025
Here's Canada's refined product sector. We basically produce what we use, with exports and imports on the margin for most products.

Andrew Leach @aleach.ca · 03/02/2025
Too many Canadians are under the impression that we export crude and import refined products in our trade relationship with the US. The first is true, and the second is true to a much smaller degree only in some parts of Canada for some fuels. In general, we're net exporters of refined products too.

Offered without comment: almost all of the US supply of nuclear fuel is imported. Here's where it comes from:

There was never a time when every hard worker had a pension. And if you factor in the share that are public sector here, a class of people PP likely doesn't think of as hard workers on the whole, the story gets even more ridiculous.

When was this Canada where "everyone who works hard gets a powerful paycheque and a pension?" And given that much of our remaining pension coverage is in the public service, how is PP going to make this happen? Expand the PS? Force private companies to offer pensions? Push unionization? What?

Glad to see the Feds moved in the direction of more flexibility in today’s announced Clean Electricity Regulations. This piece by @aleach.ca and me from a year ago holds up well… (Sorry about the paywall…) www.theglobeandmail.com/opinion/arti...
theglobeandmail.com
Opinion: Danielle Smith may be grandstanding, but Canada’s Clean Electricity Regulations do need a fix
It remains to be seen how our clean-energy transition will play out, but it would be wise for the federal government to add flexibility for fossil-electricity provinces such as Alberta

Those who enjoy reading the specific wording of the Constitution in terms of provincial jurisdiction over resources might want to take a glance at sections 91(2) and 92A(2) and (3). Section 92A(3) is particular worth reading carefully.

Where in the US does Canadian crude oil go? Mostly to the midwest, with increasing although much smaller volumes headed to the Gulf Coast. Not as much of a bump into PADD V (West Coast) as I would have expected w TMX. cc @roryjohnston.bsky.social

Seems that Alberta must have built a whole lot of wind and solar plants that all came online simultaneously on Jan 1, 2021 and drove up price levels and market volatility? Or, perhaps it was something else? Gee, I wonder what it could have been? An increase in market concentration, perhaps?
