A large industrial building sustained extensive damage following a fire in a machine shop near Dufferin and Dupont Streets on Saturday morning.

The two-alarm fire on Geary Avenue broke out just after 9 a.m. and inflicted about $400,000 of damage on the building, which houses a machine shop.

No one was injured.

Toronto Fire Services says the cause of the blaze hasn't been determined, but it's not being considered suspicious.
