Well if the government is not going to spell it out then the workplaces will. 

 I personally am aware of several workplaces that sit all the non-Canadian newcomers down in a group session and go over what is appropriate hygiene for the workplace.   The talk suggests taking a shower with soap daily (the French from France might disagree with that one),  wash your pants and shirts regularly, and most importantly do not squat on the toilet seat or wash your elbows and feet in the public washrooms.  There are also signs to this effect on the washroom walls.

The women who used to give this talk said it was done politely and tactfully and they never had any issues but prior to the 'welcome' sessions there were lots of complaints to HR. 

Personally if I was moving to a far away location for a new job I'd want them to offer the same advice to me.  When in Rome do like the Romans.
