Driving Ticket - Canada

So I'm on my way to a job interview, which I did get to on time, and got the job. That's beside the point. So I am driving 95 km/h (The Speed Limit is 100 km/h when I see a police car coming down the road the opposite direction as me. As he passed my car, he flicked his lights on, slammed on the breaks and pulled me over. He took my license and insurance slips (Which where all up to date and accurate) went to his car for what I'm sure was close to half an hour at the least. When he comes back he returns my information and gives me a ticket for
"Drive without due care, and attention'' with a fine of $280.00 CAD. It turns out the vehicle behind me reported that I was swerving, and driving like a fool, and the reason they did that I am sure is because I was driving to slow and they couldn't pass as traffic was crazy. I just want to know how in the world the judicial system thinks that this is fair? I am going to court for this to try and get the ticket dropped because it is bullshit, which means I already have to take a day off of a job I just started.. complete bullshit and I can't believe my first ticket is for something I didn't even do.
