It's Columbus day in the US and Thanksgiving in Canada
Monday is a semi-holiday in the US -- Columbus day -- so that will crimp activity. The CME and NYSE are open and SIFMA doesn't recommend a bond closure. However there is no economic data on the schedule so that could keep it quiet.
In Canada it's a different story with all markets shut for the Thanksgiving holiday.
European and Asian markets are all open but the economic calendar everywhere is light.
