Help! 3 Tickets

Today I was issued 3 tickets and have been summoned to court. My tickets include:

1) use plates not registered for vehicle-sec 12 (1) (d)

2) use validation not furnished for vehicle-sec 12 (1) (e)

3) fail to apply for permit on becoming owner-sec 11 (2)

Does anyone know what the fines/demerit point deduction will be?

Will I be able to fight the tickets in court/get tickets reduced?

I have a clean criminal/driving record.

THANK YOU, THANK YOU, THANK YOU

I believe the first two tickets would be a $170 fine each and the third $110, so a total of $450. No demerit points.

You can probably work out a plea deal where they'll drop one if you plead guilty to the other two.

Thank you so much!
