The overnight spray-painting incidents at the Ottawa Muslim Association mosque and the Parkdale United Church were condemned in the House of Commons.
Liberal MP Ken Hardie says many are concerned about what appears to be a spike in the number and severity of incidents targeting Canadian minorities with messages of exclusion, fear and hate.
Conservative MP Pierre Poilievre said the people of Ottawa stand united against the twin evils of racism and anti-Semitism.
Two Ottawa synagogues and the home of a Jewish faith leader were vandalized earlier in the week.
The National Council of Canadian Muslims denounced the spate of attacks.
“These hateful acts are disturbing,” said council executive director Ihsaan Gardee.
“As Canadians, we stand united against all forms of hatred which seek to instil fear in our communities. We remain proud of our inclusive communities and will continue to speak out with one voice to condemn those who act out on their ignorance and prejudice.”
