Just returned from British Columbia/Alberta covering some 2500km using my TTone with Map 885-4087 Canada/Alaska and the latest Speed/Safety cam updates I could find.
Only once did the Map fail, while in Banff I was told to turn right, yet the map said left.
As for the speed camera's not once did any alarms sound as none was seen, correction some schools having warning displays indicating your speed but warned they have a camera within the matrix. The only alarm that sounded which was for the Stoplight (or Redlight as they call them) camera's, but this is grossly outdated.
So anyone travelling to BC or Alberta, watch the for the Stoplight (Redlight) camera (which you are warned being present with signs) at Junctions and Police who hide behind lamp posts and do random speed checks mostly in town or city.
