No, I'm not at all saying that.
The 4th and current iteration of the welland canal opened in 1932, so the decision to go with 750' locks was made roughly a century ago, back when that seemed like a prudent lock size given that there were no vessels on the lakes in those days that exceeded that size.
Then, starting in the 1970s, American ship builders started building ore boats that exceeded 750' in length because American shipping on the lakes has always been focused on the ports in lakes Superior, Michigan, Huron, and Erie. The ports of lake Ontario and further down stream on the st. Lawrence have never been very prominent for American shipping interests on the lakes, so having ships that were too big to get through the welland canal, thus trapping said ships in the 4 upper lakes, was not seen as a terribly important issue.
However, from a Canadian perspective, the ports on lake Ontario and further downstream on the st. Lawrence have always been supremely important to Canadian shipping interests on the lakes, hence why all of the ships in the Canadian fleets still to this day max out at 740' in length, the welland canal/st. Lawrence seaway maximum.
There have been various plans over the decades to build a 5th welland canal with even bigger locks that could accommodate the largest of the ships on the lakes today, but it's never gotten past the planning stage due to money, I imagine.
Btw, the massive lake freighters I've been referencing, are self-unloading bulk carriers, not "tankers". They carry dry bulk goods like taconite (iron ore), coal, limestone, salt, grain, sand, etc., not liquid petroleum products, which are primarily transported via pipelines in the great lakes region.
There are some "tankers" on the lakes, but they're generally much smaller, in the 300 - 500' length range.
