The online portal is now open to accept responses from every household. The questionnaire appears after an access code, unique to each person, is input as instructed, said Marc Melanson, area manager for the Atlantic provinces for the census. And while the census encourages everyone to complete it by May 11, this is not a hard deadline, Melanson said. If someone does not have access to the internet or does not wish to complete the census online, it can also be completed over the phone or by calling the phone number listed inside to have a paper copy mailed to you, he said.
