On June 2, 1981 the "Normac" was struck by the "Trillium", a ferry operated by Metro Toronto Parks. The crash was caused by a mechanical failure aboard the "Trillium" which prevented the engine from reversing to slow down. The crash occurred at relatively slow speed, as the "Trillium" was in the midst of attempting to dock. None of the 132 passengers aboard the "Trillium" nor the 290 diners aboard the "Normac" were injured. Repairs were immediately made to the "Normac", and for two weeks no leak was observed on board. However, on June 16, 1981, the "Normac" suddenly sank. This set off a long legal battle between Letnik and the city. The Federal Court initially ruled in favour of the city, as Letnik could not prove the collision caused the sinking, and because he failed to properly maintain the boat after converting it into a restaurant. This decision was overturned on appeal, and Letnik was awarded damages, though reportedly not enough to compensate for the destruction.
