Anything to worry about?
As Wolfie and MIT said, it depends on the reason and their past travel patterns. The CBP official is going to be concerned with whether your in laws are using a non-immigrant visa as an immigrant visa. You should consider whether they have a good travel history and if everything is documented (flights, hotels, etc.). They should also be prepared to show why they went to Canada so that they officer can see that it wasn't just to reset the visa. There are consequences to being refused at the border, so you're wise to be asking the questions you are. Finally, don't lie to CBP.
To correct a few things said here. There are US transit visas and there is US transit. If they have a B1/B2, your inlaws don't need a transit visa. Applying for a visa and applying for entry are very different processes that are under very different laws. Extensions are commonly granted, but not as commonly granted again. In any case, I believe the extension terminates when they leave since the extension is extending a stay, which terminates when they leave. And God help anyone that drives back and forth between Detroit and Windsor 10 times in a day. Being refused entry would be the least of my concerns.
Hope that helps. Good luck.
