From Midnight Poutine, a Montreal blog:

Every Monday on my street, there is a parking ban from 9:30 - 10:30am. Ostensibly, during this hour the streets are cleaned. In reality, the chances of seeing a street cleaner on our street during that window of time is about as likely as seeing a dodo bird and unicorn filming a porno in front of our apartment. However, the chances of seeing a meter maid come by to dole out parking tickets during that time is about 110%. The city is great at fining people for not following parking signs; it's just not so great at using that revenue to follow through on the infrastructural purpose of those signs. Only Alanis Morrisette could sift through the multiple layers of irony.
