CDC says people fully inoculated against the virus can drop some precautions when gathering with others.
However, at least two provincial health ministers, in Ontario and B.C. say existing public health advice for this country holds for now.
One infectious disease specialist says virus variants with the potential to break through vaccine protection are a ''wild card.''
Under the new protocols from the CDC, vaccinated people can visit other vaccinated people indoors without masks or physical distancing.
Canada's case count sits at 890,698.
The virus has claimed 22,276 lives across the country.
