COVID-19 pandemic had already led to difficulties, but a recent Manitoba vaccine mandate means school bus drivers are in even shorter supply, says the president of a local bus company.Some Manitoba school divisions — including Seine River south of Winnipeg — have suggested they’ll have to limit bus service only to those students who live further away if the situation worsens.BJ Langdon of Tony’s Team Transport told 680 CJOB the problem is months in the works and is only being exacerbated by further restrictions.“We talked about this in the summer, about how bad it was and how it was probably worse with COVID,” he said.“Now, I guess, with the vaccine mandate that’s in place and some of the regulations that started on Monday, it’s exaggerated.
