It's gotten worse since the hours-of-service laws changed a few years back. Drivers try to maximize everything. They don't do split sleeper berths, so if they don't plan their trips appropriately or if they get delayed due to accidents, traffic or weather, they end up stopping in places that don't have services.
I believe we have added two rest areas in northern Ontario. One is Batchawana Bay and one is right at the Manitoba border. I believe the one at Batchawana Bay has parking for six trucks. I can tell you that last week the road was closed at Batchawana Bay for 39 hours. Six trucks can park there. Six trucks can go to the washroom there. The others—I'm going to guess 1,000—can't. It's huge.
