Protests by Wet'suwet'en supporters spread across British Columbia again on Monday afternoon, blocking public transit, the Port of Vancouver and the stairs to the B.C. Legislature.

The fresh demonstrations came after police in Ontario made several arrests earlier Monday while clearing a rail blockade in Tyendinaga Mohawk Territory erected in support of the Wet'suwet'en hereditary chiefs who oppose the Coastal GasLink pipeline in northern B.C.

All West Coast Express trains heading east from Vancouver to Mission were cancelled Monday afternoon during the rush hour commute as protesters blocked tracks in the Port Haney area.

The tracks were clear by evening, and the trains are expected to run regular service Tuesday morning.

Crowds gather at B.C. Legislature

By mid-afternoon, hundreds of people had gathered near the entrance to the B.C. Legislature.

Police stood on the stairs flanking protesters, but there were no reports of arrests. Later, protesters blocked the progress of a police van that arrived at the legislature. They linked arms and chanted, "peaceful and with love, unarmed and non-violent.''

We're bringing one of our vans to the Legislature driveway. This is to keep our officers warm - it's chilly down there. This is NOT a precursor to arrests. <a href="https://twitter.com/hashtag/yyj?src=hash&ref_src=twsrc%5Etfw">#yyj</a> <a href="https://twitter.com/hashtag/F208353?src=hash&ref_src=twsrc%5Etfw">#F208353</a> —@vicpdcanada

Some protesters locked themselves to a gate at the legislature, which was the scene of a large protest on Feb. 11, which prompted the province to obtain an injunction when entrances to the building were blocked.

Organizers said Monday they're staying for the long haul.

"We are not here seeking arrest,'' said Indigenous youth leader Ta'Kiaya Blaney, speaking with a megaphone. "We are here as our duty as Indigenous youth. Bring your blankets, it's going to be a long night.''

Protest at Vancouver port

Nearly 100 people also blocked access to the Port of Vancouver at East Hastings Street and Clark Drive, preventing container trucks from leaving the port.

An injunction, granted by the B.C. Supreme Court on Feb. 9, is still in effect at the port. A spokesperson with Port of Vancouver said it is working with police to address the protest.

More than 50 demonstrators were arrested at ports in B.C.'s Lower Mainland in earlier protests this month.

A new CN Rail blockade was also set up in northwestern B.C. on Monday near New Hazelton, north of Smithers, less than two weeks after one was dismantled at the same location.

The railway runs through the territory of Gitx'san Nation, members of which were at the blockade.

On Monday evening, several people were arrested at the blockade, according to Linda Stephens who saw her husband Gitx'san Nation Hereditary Chief Spookw arrested by police.

"People are pretty upset that these hereditary chiefs are being arrested on their own territory," she said.

A number of people had been occupying the Mohawk territory for weeks in solidarity with the hereditary chiefs of the Wet'suwet'en First Nation, who oppose the development of the Coastal GasLink natural gas pipeline — a project that would cross their traditional territory in northern B.C.

The Ontario blockade has brought freight and passenger rail traffic to a virtual standstill since it was built on Feb. 6, near Belleville. On Monday morning, dozens of police officers arrived at the encampment and began making arrests after demonstrators stayed past a midnight deadline.

Numerous similar rail and road blockades have sprung up in multiple provinces throughout the month, halting freight and passenger train service for much of the country.

A representative with Monday's demonstration in Vancouver said solidarity actions will continue until the demands of the Wet'suwet'en hereditary chiefs have been met.
