Get ready for another day of heavy traffic and clogged parking lots in the capital.

Thursday marks the third in a series of rotating one-day strikes by Local 591 of the Syndicat uni du transport, which represents bus drivers and mechanics for Gatineau's transit service.

The union has been locked in a labour dispute with the Société de transport de l'Outaouais (STO) and earlier this month announced they would begin weekly one-day strikes.

The transit workers have been without a contract since December 2014.

Last week's strike day saw parking spaces in downtown Ottawa fill up quickly, almost certainly because of an influx of Gatineau commuters who decided to drive to work.

OC Transpo buses are running to Gatineau.

One saving grace is that the local forecast calls for sunny skies and a high of 7 C — so some of those drivers might just choose to bike or walk instead.
