No. Not unless you run a Garmin unit, and then your options are very limited too, and probably not as good as the Navionics maps for CA. Lowrance has added the “Gold” mapping package to some of their new units for 2011, like the Elite-5 DSI Gold. Gold units include 125 Canadian lakes, preloaded. But as far as adding a map chip to a current Lowrance or Humminbird unit, Navionics CA is your only option unless you are just going to Rainy/LOTW.
