AFAIK only the F-100 from Navinata uses a Spy-1 system though I'm not sure if Aegis is part of it (as Aegis is the entire defensive system not just the radar). Personally I think Aegis is a little bit overrated (not saying it isn't good, just not as good as it publicist would suggest). It would also be in Canada and the US's benefit to have different defence and sensor systems. This means they will each have different advantages and disadvantages so can cover each other off in combined operations.
What you're primarily looking at is a version of the APAR/SMART-L system from the Dutch, Germans and Danish. A Sea Fire 500 or variant from the French and a Selex ES from the Italians. The British Type 26 is currently looking like it will mount a type 996 3D radar. I'm sure I missed something but really going by just odds its a 1 in 8 chance of Aegis.
