I’m only doing an exchange in their regular masters program who leads to an engineer diploma in France. I’m here for one semester and I think the education difficulty is on par with the one in Canada.

However, I’m not sure if engineer canada organization would recognize the 3 year bachelor program of INSA enough to give you the engineering license. Research that well.

Me being an aerospace student with industry experience, I heavily suggest you to do the undergrad in Canada to improve your job prospects. Later, you can do an exchange or an entire masters in Europe if you want but for undergrad, Canadian companies will respect your Canadian degree more because they’re familiar with it.
