CJAD broke a story last fall about a young woman who was attacked by a cabbie. When victims started speaking to the media and the problem became known, the provincial government put in place mandatory background checks for taxi drivers. That came into effect last month.
But the number of sex assaults in cabs spiked two years ago, going from 12 in 2012 to 33 in 2013.
Montreal police constable Ian Lafreniere says they didn't launch a public awareness campagin sooner because that number is considered very low.
"It could look like a pretty big number but when you look at the number of rides that these people are doing, we're talking about 37 million rides per year, and again one is one too many, but it is safe and it is still the right way to go home at the end of the day," he said.
In 2014, there were 27 reported sex assault cases, one arrest was made. That person has not been prosecuted yet but should appear in court within a few weeks.
Lafrenière says of 200 cases over the last decade only 20 suspects were prosecuted mainly because the court process is long and challenging for victims.
"A lot of people decide not to go further in court and we respect that," he said.
