The public health measures at the beginning of the pandemic were the absolute driver. It was the fact that the Public Health Agency was collecting the information it needed from incoming travellers in paper and was not able to process that paper in a timely way to get provinces and territories the information they needed. It was for enforcement and compliance to be undertaken by the Public Health Agency.
This was very quickly discovered, which is why, the same month that the pandemic was declared, the request came to CBSA to develop an application that could digitize those forms.
