They don't provide washrooms anymore. They told us to use washrooms at Eaton centre. They didn't put any sign on their washrooms that could inform customers there. There were few people waited for washrooms when I walked pass so I had to tell them.
However, you can secretly lol use washrooms at Best Buy or Starbucks :) we ended up with spent money there because I went there to use a washroom lol oh Best Buy's washrooms were very clean ^^ and no line up.
