No nothing new. Expect a P25 system and almost certainly encrypted.
I've been a firefighter for a while, and have been friends with numerous ones most of my life. And if experience has shown me anything it's that most guys know squat about the radio system, the technology or much else about it. Turn the radio on and talk, that's what they care about. Yes KW does run medical calls but very little patient info is transmitted over the air, and online streaming isn't nearly the issue that it is for police.
Off the top of my head Hamilton is the only encrypted fire agency in SWO. There just isn't a big need for it or the expense.
Saw my buddy on the long weekend who is a firefighter in the region. He basically said what mrozitis said. Fire will be encrypted because they cant share details over the air due to online scanners and no MDTs in fire trucks. The low grade encryption is free on radios now though. Will be sad to see the last analog system go in the GTA.
Update I could find:

The new Waterloo system is 100% encrypted, all infrastructure, all users, all the times and that is why the changes to the in building coverage testing. It apparently will be like Hamilton with everything from the little sidewalk snowplow to the emergency services 100% encrypted.
They did spec out three options I believe and all three mandate full encryption at AES-256 bit but one of the options allows for low-level ADP encryption for a link with Brantford police. It's done, I saw Harris radios being installed last August and I am sure most have the new hardware by now....can't confirm tho.
Does Harris even support ADP?
I'm not even sure why they would have a link with Brantford anyways? Their areas don't even border on one another.
