Do you have more context for the gerrymandering attempt? I don’t remember that one, and web search is terrible now so I can’t find more about it either.

In Canada, independent commissions handle the process, which makes gerrymandering much more difficult to get away with. An article discussing it:

“Independent commissions now handle the redistricting in every Canadian province”

Eventually, in 1955, one province — Manitoba — decided to experiment, and handed over the redistricting process to an independent commission. Its members were the province’s chief justice, its chief electoral officer, and the University of Manitoba president. The new policy became popular, and within a decade, it was backed by both major national parties, and signed into law.

Independent commissions now handle the redistricting in every province. “Today, most Canadian ridings [districts] are simple and uncontroversial, chunky and geometric, and usually conform to the vague borders of some existing geographic / civic region knowable to the average citizen who lives there,” writes JJ McCullough.

“Of the many matters Canadians have cause to grieve their government for, corrupt redistricting is not one of them.” Hoffman concurs, writing, “The commissions have been largely successful since their implementation.”
