Operations at Toronto's Pearson International Airport were in recovery mode on Saturday after nearly 190 flights were cancelled or delayed one day earlier due to a labour disruption.

In a tweet sent out Saturday morning, a spokesperson for the airport said operations were "running normally." However, travellers were still encouraged to check the status of their flight before heading out. 

On Friday, 185 flights had to be cancelled or delayed due to a protest by workers who are facing potential job losses when a refuelling contract changes hands in the fall.

Beginning Oct. 1, a number of airlines are switching their refuelling business to Service International Group in Toronto.

According to a union spokesperson, employees of Consolidated Aviation Fueling Services will be required to apply for similar positions with Service International. The workers, however, will likely be paid less and will not have a pension.

A release by the union says approximately 300 of its members in Toronto and Montreal will lose their jobs by October.

"Basically these guys are all going to lose their jobs Oct. 1, and so I think frustration is they key phrase," Bill Trbovich of the International Association of Machinists and Aerospace Workers told The Canadian Press.

He said workers currently earning between $18 and $23 per hour will likely start at minimum wage, up to a maximum of $14 per hour.

The labour disruption mostly affected Air Canada, which uses the Toronto airport as its main international hub.
