At least, not today. According to an article from CNN:

The White House declined Monday to commit to reopening its northern border to Canadians after Canada’s government said vaccinated US citizens would be able to enter on August 9.

“We are continuing to review our travel restrictions and any decisions about reopening travel will be guided by our public health and medical experts,” press secretary Jen Psaki told reporters at the White House briefing. “We take this incredibly seriously but we look and are guided by our own medical experts. I wouldn’t look at it through a reciprocal intention.”

While this will not impact as many Canadian travelers as the Canadian announcement impacts US travelers, Canadians living in border towns looking to cross into US via land is still a no-go. Canadian folks who wish to get cheap gas or make a visit to that Costco 10 minutes south of the border will just have to keep waiting.

Keep in mind this does not impact air travel in any way, as Canadians have always been able to fly to the US throughout the COVID-19 pandemic.
