the most common reason for court to appear is for child support. Is there any address attached to the inquiry? I wouldn't dispute it with the CRA as the law makes no difference between "soft" and "hard" but rather the difference is between inquiries that can be disclosed to third parties and those that can't. In other words, the non-PP penalty applies to both what we call soft and hard inquiries. I would pursue this as a case of non-PP until the instigator can prove otherwise.
If there isn't an address listed on the report you obtained, this may be a good instance to actually call the CRA.
