 The Canal Street subway station was actually filmed in Torontos  "Bay Lower" unused subway station. $150,000 was spent on set  dressing alone. The TTC (Toronto Transit Commission) was so  impressed with the New York conversion that they actually requested  the set to be left up after filming was completed to attract future  filming revenue. The set remained for about three weeks until TTC  fire inspectors deemed the set a hazard (steel girders, signs and  benches were plastic and wood), so the set was torn down and  disposed of.
