Agreeing with other comments, it is a Chinese domain and a Chinese news site so doesn't necessarily reflect Canada as a whole.
The article is talking about an n = 1570 study where 61% or people say they supported the trade deal with regards to EV (the article doesn't specify whether the canola export portion of the deal may have influenced perceptions). All in all, it's the other side of a trade deal pointing at roughly 1000 people saying they are for the deal and saying "see? Canada supports the deal".
All this said, had I been asked I would be in the "strongly support" camp (noted as 24% in the article). The EV tarrifs were not completely removed, but removed for up to 49000 total sales under a certain value per year. Those tariffs were put in place as a measure to a) dissuade the Americans from increasing tariffs against us and b) prevent cheaper Chinese EVs from undercutting Musk's market share. The tariffs were increased anyways and why should we continue supporting that piece of trash.
Do I think Chinese EVs will save the world? No. Do I think that China is an objectively good state? No. But I do think that removing those tariffs is a good thing.
