A picket line has formed in front of Niagara College in Welland.
Striking workers are picketing at all entrances, but are not holding traffic back for an extended period of time.
The workers are handing information leaflets to vehicles.
Faculty at Ontario's 24 colleges are walking picket lines today, with the labour dispute affecting more than 500,000 students in the province.
The strike involving more than 12,000 professors, instructors, counsellors, and librarians began late Sunday, after the two sides couldn't resolve their differences by a deadline of 12:01 a.m. Monday.
Both sides say there are currently no talks scheduled to end the dispute.
The Ontario Public Services Employees Union says it is up to the College Employer Council, which bargains for the colleges, to re-start talks.
The union presented a proposal Saturday night that called for the number of full time faculty to match the number of faculty members on contract but the colleges say it would add more than $250 million costs each year.
OPSEU bargaining team chair JP Hornick says the union remains ready to get back to negotiations.
