Yes, it is a requirement and is usually checked by immigration, much before you get to the crossing point. My wife had to do it several times and its a quite simply and fast process. We used a letter provided by the Government of Canada site and had brought it to city hall to have it certified. The process took a few mins for a nominal fee (under $10 IIRC).
Once I did not have that document because the mother was nowhere to be found and instead presented the court order awarding me sole custody of the children when immigration asked about the mother. That also worked but required more checking. The former is more common, so if you can have the letter and the mother sign it, it would be best.
