Due to many of our lead and company records not having populated country fields, I’ve created a series of smart lists to find other populated attributes that show them as Canadian: a province in a state field, the first three letters of a Canadian postal code in a postal code field (codes were found on Wikipedia), phone numbers starting with a Canadian area code, or the inferred country being Canada. When running the lists I first look at the lead data, and if that doesn’t give me an answer I look at its company record.
