Mr. Speaker, the Minister of Immigration, Refugees and Citizenship did not order the change of the word "illegal" to "irregular" on IRCC's website. The decision to standardize the terminology was made by the department to minimize the mischaracterization of asylum seekers as being in Canada illegally. In accordance with Canadian and international laws, until their claim is decided, or if they are found to be a refugee, a person will not be charged with an offence based on how they entered Canada. The updates to the website were made on an ongoing basis, and incrementally from the fall of 2017 to the summer of 2018 to reflect the fact that it is not illegal for someone to claim asylum in Canada after entering at any point along the Canada-U.S. border.
