I mean not necessarily. HOVs are ultimately "underutilized" compared to regular lanes and theoretically could be removed to see slight improvements in traffic.
Along the QEW in Halton, MTO originally built the corridor for 10 lanes, IIRC, but the decision to implement HOVs meant they could only do 8 lanes as the HOVs were wider. In that case, MTO could relatively inexpensively eliminate the HOVs and convert the highway to a 10-lane cross section, substantially improving capacity.
I don’t think that was the intent there. Five through lanes would still bump against the QEW/403 split at Burlington, which is already very congested.
But the suggestion that “just one more lane will fix it” for the QEW sounds like a very bad idea.
