opp encrypted ?

I'm a newbie and just purchased a BCD436HP, I am familiar with the old scanners but was hoping with all of the intentions of listening to the OPP, Fire, Ambulance again in the Stormont, Dundas and Glengarry Cornwall area region, I've picked up one OPP encrypted 142.0350MHZ MFN . Picking Ottawa Ambulance really well but not Cornwall, and no Cornwall fire dept. ? Am I reading this right as the summer begins the opp and so on are all going encrypted ?

opp encrypted ?
