Their searchable database lets you search during specific years, by province, by the type of incident, and by the number of cartriges/spin cycle used by the officer. You then get a list of reports and can read the details from the report.
In a quick look I found that there were 23 recorded times when eight or more stun and cartrige cycle were used since 2002. And That there were six recorded incidents of tasers being used on cell blocks.
On the CBC website they write:
“By putting a searchable version of our database online, we hope that people can discover a few more details about the use of a device that has been the subject of increased public scrutiny and political debate after the death of a Polish immigrant, Robert Dziekanski, who died shortly after being stunned five times with a Taser at Vancouver International Airport in October 2007.”
