"Ion propulsion system designed partly in Canada." The last I looked, the most advanced ion engine was primarily designed by Ad Astra in Texas. It's the VASIMR engine. Yes, Canada builds one of the main pieces of hardware for it, yes they were involved. I'm not trying to take that away from Canada, its just that you obviously skipped over any details of the origin of the engine, or you didn't bother to do any actual independent research. Or you're just the Al Gore of Canada, inventing the internet AND ion engines.
"The ion drive engine is able to turn electrical power into thrust, which would make solar panels extra useful." Do you think solar panels would generate enough electricity to reliably power these things? The current VX-200 generated 201 kilowatts, enough to keep the ISS afloat using .3 tons of fuel. I've seen estimates for a Mars mission requiring a 10-20 megawatt ion engine. That would require some serious solar panels... but then again I hear they build everything bigger in Texas. Maybe they'll have a couple of square miles of solar panels strapped to that baby.
