Maybe I'm reading too much into it, but I actually thought this one line was very telling and shows that Sousa knows the issue (but just won't/can't say it).

"Could be speculators" (*cough* foreign investors)
"could be people from outside the country" (*cough* foreign investors)
"could very well be the many who are now moving into Ontario" (*cough* foreign investors)

The way the statement was made makes it appear like he's referring to different groups but as with all good politi-speech, maybe... maybe not...
