Truck trains rolled slowly through Alberta and Saskatchewan on Saturday, while demonstrations in support of Canada's oil and gas sector continue.
Medicine Hat police in Alta estimated that 650 vehicles participated in a convoy that began on the Trans-Canada highway east of the city and continued west to scales before turning around and dispersing.
A similar event in Estevan, Sask., Brought about 450 trucks, according to a police estimate.
Truck trains started last weekend in Alberta. An event on Wednesday brought more than a thousand vehicles to Nisku, south of Edmonton.
Jerry Sabine, the train organizer at Medicine Hat, says the trucks were driving slowly to show people "the frustration of how slow the oil fields are."
Premier Scott Moe of Saskatchewan tweeted his support for the event in Estevan, saying people in western Canada are fed up with what he called the Trudeau government's indifference to the energy sector.
"What a strong message sent today from the truck rally in Estevan," Moe said. "Your SK government is with you in support of this critical industry."

Other recent rallies, including a major rally in Calgary on Monday, target federal lawsuits that critics say will hamper pipeline construction. They include Bill C-69 to renew the National Energy Council and Bill C-48, which would ban oil tanker traffic off British Columbia's north coast.
Proponents of Saturday's trains lined the streets in both cities. Most of the billboards they owned contained messages calling for the construction of an oil pipeline, the end of carbon taxes and the defeat of Prime Minister Justin Trudeau.
Some of the signs also expressed opposition to the United Nations.
Jay Riedel, organizer of Estevan's convoy, said concern over the signing of the United Nations pact on migration is part of the protest, noting that he believes the pact gives Canada's immigration policy to outside powers.
"We definitely need immigrants arriving in Canada, but we also need to get jobs for them and them," Riedel said.
"If we do not have jobs for these people, our whole social system will fail."
Police in Medicine Hat and Estevan praised the conduct of the train drivers.
"Appreciate the public's patience during the train convoy protest. Also enjoy the professionalism of those involved," said a tweet from Estevan police assigned to chief Paul Ladouceur.

More trains are being planned, including one that will travel to Ottawa in February. Sabine said some of the trucks involved in the Medicine Hat train had traveled from all over the province to support the event.
"We just released a pair three days ago and it really turned into a snowball," Sabine said.
