Striking transit workers aren't backing down as York Region takes them to court over their picketing tactics during the nine-week-old strike.

York Region Transit workers who walked off the job Oct. 24 continued to picket Tuesday, despite the region's decision to seek a court injunction against the picketers.

For the second consecutive day, workers blocked vehicles, including garbage trucks, at a Miller Transportation yard on Woodbine Avenue in Markham.

Workers also picketed outside a Veolia Environmental facility in Pickering, a facility on Jane Street north of Highway 407, and a transit garage at Keele Street and Bowes Road, where they held up buses for several minutes at a time.

The TTC's 107 Keele North and 35 Jane buses were among those delayed.

For people who are frustrated by delays caused by the picket lines, there is some good news. Striking workers will take a break from picketing during the Christmas holiday.

York Region is seeking the injunction against Amalgamated Transit Union locals 113 and 1587, accusing them of staging "unlawful" pickets that have caused "unreasonable delays" for people who live and work in the region.

An injunction would limit picket lines and, according to York Region, ease delays.

The region claims the picket lines by striking York Region Transit/Viva workers have created unsafe conditions for transit riders, motorists and pedestrians.

A lawyer will be in court Thursday to ask for an injunction.

Pickets have ramped up their efforts and caused significant delays in recent weeks, setting up outside YRT facilities, transit stations and a Miller Transit facility.

More than 550 workers, employed by Miller Transit, First Canada and Veolia Transportation, who are all contracted by York Region, went on strike Oct. 24, shutting down about 60 per cent of the region's bus routes.

The strike is affecting more than 44,000 riders every day.

ATU Local 1587 represents about 340 bus drivers and mechanics in YRT's southeast and north divisions, while 220 Viva employees are represented by ATU Local 113.
