Default [Q] Unlocking + Using in Canada

So I bought the HTC One M8 with the intention of unlocking the phone and using in on Canadian Carriers, but as I try to unlock the phone, I am increasingly becoming worried that sucha a thing is not possible.
I see that band Sizes on the CDMA Sprint versions match up with those on Canadian carriers (Except LTE).

I'm trying to get an unlock code from paid websites, but all of them are to be used with GSM carriers. Am I boned?
