Your view is a very naïve one. 
There are certainly Chinese in Canada that support the Chinese Gov't.
There are certainly Chinese in Canada stealing our technology for their Gov't -Nortel was one example where National Defence which is relocating to the former Nortel HQ in Ottawa, found many bugs planted by the Chinese as they renovated. You might also take note of our own Gov't publicly acknowledging Chinese cyber attacks on our Gov't institutions.
China, and their agents, are not to be trusted.
