I took a right turn on yellow turning to red at Castle Frank and Bloor St. and was issued a ticket based on MTA 144(9).

Any tips on getting the ticket thrown out?

A sign is not a traffic control signal. A sign is articulated under s. 144(9), for which you were charged. You drove through a yellow on a traffic control signal system. A traffic control signal system is defined in s. 133.

You should've been charged under ss. 144(15) or 144(18).

You cannot be convicted for something you did not do. You did not violate s. 144(9) unless there is a sign that forbids right turns.

Is there a no right turn sign at this location?

Read ticketcombat's website on procedure and for what you should do.
