Eh, I kinda doubt that this still true at this point in time. Also, the Trump flags next to F*ck Trudeau stickers is jarring.
That is certainly not universally true. There are aspects that are certainly different from US conservatives and in some cases (e.g. firearms) it is because they cater to a radical minority.
So I would say that Canadian extreme right has less sway over the party than in their equivalent in the USA (which at this point is largely dominating the party). However, especially on the provincial level conservatives are adopting (perhaps milder) US style campaigning and have sowed vaccine skepticism (https://www.nationalobserver.com/), tend to ignore climate change and for some reasons are obsessed with trans folks.
Looking at the US election, 44% of Canadian conservatives prefer Trump over Harris (36%) (https://www.environicsinstitute.org/docs/default-source/default-document-library/read-the-report6589c781-7dd1-40c2-b3ad-372bb98c1aa1.pdf?sfvrsn=cac8947f_1). That is clearly more US Independent territory than Democrat.
Likewise, on abortion rights, Canadian conservatives are far more in favour (66%) compared to the US Republicans or even Independents (34%/58%) but still less than US Democrats (89%). Canadian Liberals are closer to US Democrats (91%). Economically, on statements of social and economic justice (i.e., government should do more to make sure racial minorities are treated fairly and government should reduce income gap between poor and rich), Canadian Conservatives (62% and 58% in favour) are close to US Independents (64%/50%) than US Democrats (93%/87%). The percentage is still higher than US Republicans (36%/34%).
Still, while Canadian conservatives as a whole are are more to the left of US Republicans, they are closer to Independents rather than Democrats. Some surveys do show further movement to the right in Canada, especially in some provinces, suggesting that the polarization in USA, which has been largely absent until ~2019 in Canada might also start to settle in.
