Singing an impromptu ditty on a Winnipeg bus could land you a $100 fine.

The city's executive policy committee approved a new transit bylaw on Wednesday that makes singing on a Winnipeg Transit bus a ticketable offence.

The rule came as part of a larger transit bylaw that makes it against the law not to pay your bus fare and establishes an array of “inappropriate conduct” for which someone can be kicked off a bus or fined.

The provision for the city’s more “musical” guests, says without permission from Winnipeg Transit, no one can play a musical instrument, sing or offer a live musical performance on a city bus or face a fine of $100 plus court costs.

The new bylaw also made provisions for banning people from the public transit system and limiting the time a person can wait in a bus shelter to 90 minutes.

The bylaw listed a number of fines associated with each infraction. Specific fines for “minor offences” would be $100 “plus court costs.”

Earlier this year, Winnipeg saw numerous musical performances on buses as part of JunoFest, and in 2007, the White Stripes make an unscheduled appearance on a city bus.

The duo sang to fans on the bus before getting off for an acoustic set on a city bridge.

Winnipeg Transit itself released an ad in the 1980s that featured singing bus drivers. The ads encouraged ridership while a chorus of voices sang, "Why don't you take a bus and leave the driving to us?"

The bylaw will now go for a final vote before city council.
