Manitoba is tightening its borders and ordering all travellers to self-isolate for two weeks, over concerns they may bring new, and more transmissible, coronavirus variants across provincial lines. At a hastily called news conference Tuesday, Premier Brian Pallister announced changes to public health orders that require anyone who enters Manitoba to self-isolate for 14 days. The move will take effect Friday. It will include travellers from Western Canada, the northern territories and west of Terrace Bay, Ont. — who are not required to self-isolate under current health orders.
