The spontaneous generation of parity- (P) and time-reversal- (T) violating masses in (2+1)-dimensional QED is studied in the large-N limit, where N is the number of two-component complex fermions. Energy considerations of various symmetry-breaking patterns indicate that P and T are not spontaneously broken, even though masses which individually violate these symmetries are dynamically generated.
