Canada Day is the official start to summer vacations. If your not heading out of town or to the cottage why not hang around amongst the masses.
If you are not ready to tackle the big crowd downtown, why not host a BBQ for your friends and family? Or simply grab a blanket and pack a basket and head off for a nice picnic. Ottawa and Gatineau have many great areas for picnics.
