Some Canadian hospitals are collecting used N95 masks so that they can be decontaminated and worn again should new ones become impossible to find amid a global scramble for personal protective equipment caused by the coronavirus pandemic.
The issue has become more pressing in Canada after the United States blocked some exports of protective gear. On April 5, Canada's chief medical officer, Theresa Tam, said hospitals should not throw away medical masks, including N95 respirators, because it may be possible to disinfect and re-use them.
The CHEO Research Institute in Ottawa is preparing to sterilize the masks with ultraviolet light for the CHEO pediatric health center.
US President Donald Trump has directed federal agencies to use any authority necessary to keep highly sought-after medical supplies in the country, kicking off a diplomatic spat with Canada over N95 masks produced by 3M Co.
Canada's deputy prime minister, Chrystia Freeland, has characterized the market for medical equipment as "a Wild West," and the government is encouraging more domestic production of medical supplies.
