Narrative:

Landed on runway 15 at tlc (mmto). Tower told us to roll out to the end of the runway and turn right on taxiway Q. I rolled out to the end and made a right turn on taxiway 'east'. Tower informed us that this taxiway was not authorized and we were to stop and wait for a tow. Taxiway 'east' is at the end of runway 15 but there is no sign or any other indication that this is taxiway 'east'. Taxiway 'Q' is 200 ft into the overrun. There is a sign for taxiway 'Q', however the sign was unlighted and not visible from the end of runway 15. I feel that if proper signage were used this problem would not have occurred.
