They did to a degree, but when it came to freedom-destroying election issues, the parties pretty much focused on our very own C51.
The TPP was mentioned here and there, though more with respect to the secret courts (aka sell your sovereignty to the highest non-domestic bidder) than copyright.
Supposedly Trudeau's cabinet was going to "review" the TPP, whatever the hell that's supposed to mean. I can't imagine they did anything thorough in the amount of time they've been in power -- the treaty text is just too damned long and convoluted. Regardless, they're still planning on signing it so I guess any review they did manage to get done ended up as "status quo."
No mention of CETA that I saw, though that's not just during the election -- CETA gets significantly less coverage across the board than the TPP. I have neither the time nor legal expertise to work it out for myself but from what I've read, the two treaties are quite similar other than the participants, suggesting that CETA will probably screw us at least within an order of magnitude of the TPP... but it's missing the "ermg we'll be taken over by America!" factor that makes the TPP so much more newsworthy up here.
