"Roughly 90% of Canada’s total oil exports go to the U.S., with about 16% of that specifically destined for the Gulf Coast."

Pretty close. The net sifter says about 18.6%.

How much oil does Canada export to the US? About 4.3Mbod, in 2024.

So, 18.6% of Canadian exports to the US, which go to the Gulf Coast, amounts to about 800,000bpd.

How much oil does Venezuela export? About 800,000bpd.

How much oil does Mexico export to the US? 733,000bpd, in 2023.

So, by seizing all Venezuelan exports, at current levels, Generalissimo Trump the Magnificent can replace virtually all Canadian, or Mexican, crude refined in the Gulf. Venezuelan production could be doubled, and find a ready market in the US Gulf refineries, displacing more Mexican and Canadian.

And flow in a pipeline can be reversed. The Seaway line was reversed some years ago.
