I have. I think it was in the late nineties or early 2000s. Someone I was searching for was a fugitive from overseas and was wanted in Canada. I located him. We ended up arresting him. He was deported back to a Caribbean country. When he returned there, he called me on my personal cellphone and told me he was going to kill me. Not thinking anything of it because he was back in his own country, when I looked at the telephone number, I saw it was a local Toronto number. A few days later, he sent someone to my home, apparently to try to kill me. The RCMP did a threat assessment, and they moved me and my family out of the country for a period of time. I worked at a diplomatic posting overseas.
This was in relation to an investigation with CBSA.
