Sure.
I should be clear that I'm not an engineer, but the standards are set by Industry Canada and are designed primarily to ensure that the device can operate safely, because we are talking about an electrical device. It's similar to what you'd see for any electrical device. The standard is set to ensure that it will not harm the user, and a plug-in electrical device into a complex network could cause damage, I'm told.
It's not something that we see frequently nowadays. The standards have been in place for a long time and most devices are very much in compliance.
