Toronto rock band Ontario Power Generation was sent a cease-and-desist by provincial nuclear concern Ontario Power Generation. OPG (the band) was getting to be known around town for their geeky one-off cover sets. Star Trek and Street Fighter II are two that have been caught on tape. The story started on local blogs but has now been picked up by the city's tabloid, The Toronto Sun. This isn't the first time a band had to change it's name when it came in conflict with a government agency.
