Also, laying asphalt is cheap compared to public transit. At say a million per km for the lane, that would only pay for 1.3 GO buses.

Asphalt isn't that cheap. Following Ontario's standards, an HOV lane requires a wider left side shoulder, as well as a striped buffer. An HOV lane is also wider than a standard left-hand freeway lane. So add all that up, and the pavement, and subgrade costs about 20% more than a similar widening for just a general purpose lane.
And that doesn't include costs associated with building new ballast walls under bridge abutments, or changes to drainage systems because the freeway cross-section needs to be wider than originally envisioned, or moving electrical systems, or heaven forbid the cost of additional property acquisition.
I'd bet the QEW widening through Halton Region could have been done for just over half of the price of what they paid for an HOV lane if they just added a fourth general purpose lane in each direction rather than going with an HOV lane.
