The British Columbia ports labour dispute continued on Tuesday, impacting exports at Canada's biggest port in Vancouver with no sign of negotiating progress.

Dock employers in British Columbia said they will shut out workers on Monday in response to a union’s strike notice, grinding trade to a halt at terminals across Canada’s busiest and third-busiest ports.

The BC Maritime Employers Association said it would lock out workers on Monday at Canada's Port of Vancouver after a negotiating deadline passed, potentially disrupting exports of coal, potash and beef.
