Tried to book TLL-YYZ for later this year. Online, I could not get the full thing to show up.
As a multi-city, it priced out close to 150k p/p in J and ~$120 in tax:
TLL-ZRH-YUL on LX was 70k p/p in J
YUL-YYZ was 79k p/p in J

Called in and they were able to book as a one-way which priced out to 69k and $79 in tax p/p.
