I’m not convinced that lead has evaporated or even substantially dropped, if we’re using public polling as a measure. Accounting for outliers to either side, on the balance the LPC still seem to have a comfortable lead:

The question of Carney vs LPC, and Poilievre vs CPC is also fair game. Poilievre personally seems to co to use to underperform his party more broadly in opinion polling, as has been discussed here recently.

Fournier from 338 Canada on exactly this, and the discussion at that time did reflect the present polling averages. Part of the discussion was how ‘nothing happens over summer’ and Canadians largely tune out, so gauging public opinion meaningful may need to wait til a couple weeks after Parliament resumes.
