As Toronto continues to crack down on illegally parked vehicles, police say an ICS Courier van is the city's worst parking offender with 612 outstanding tickets.

That amounts to approximately $33,400 in outstanding fines, the Toronto Police Service's parking enforcement unit says. The same company also has the second-most ticketed vehicle, with 468 outstanding tickets and more than $28,000 in fines owing.

Both vehicles have Alberta plates.

Under old city rules, out-of-province vehicles would not have been included in Toronto's "Tag and Tow" campaign, which aims to reduce gridlock during rush hour by ticketing vehicles illegally parked along major roads.

But in January, Mayor John Tory expanded the city's zero-tolerance towing policy to include vehicles from other provinces and states that are repeatedly written up for parking illegally. The new parking policy came into effect this month.

Out-of-province vehicles with three or more outstanding Toronto tickets are now immediately towed. Drivers are also subject to towing fees of approximately $200, and a storage fee of up to $80 per day.

In a statement to CTV Toronto, ICS says it is "committed to serving Torontonians in a timely and secure manner without adding to the city’s traffic congestion.”

It added that, "along with other courier services, we are working with the Canadian Courier and Logistics Association to find workable solutions to this industry issue."
