From a media release:
Discovery announced today that production is underway onÂ HEAVY RESCUE: 401, a new original Canadian series set to debut in 2017 based on the networkâ€™s hit series HIGHWAY THRU HELL. With the support of the OPP, Ministry of Transportation of Ontario,Â York Regional police,Â maintenance contractors, andÂ several other organizations, the new documentary series follows the men and women who keep Ontarioâ€™s 400-series highways operating at any cost.
Spanning the Greater Toronto Area and southern Ontario,Â HEAVY RESCUE: 401Â follows multiple major tow operators, rescue, and maintenance crews day and night along North Americaâ€™s most intense stretch of highway. From Sarnia eastbound to Toronto and north to Barrie, the cast of heroes work diligently to keep Canadaâ€™s most important and busiest series of highways open through any weather condition. From monster snow storms creating kilometers of mayhem to trucks spilling their loads, these efforts safeguard the countryâ€™s most important trade route with the U.S. from grinding to a crippling halt through the worst of the winter driving season.
