COVID-19 Pandemic Logistics Update

Due to government mandated lockdown rules and closures, we are obligated to operate with reduced staff under extraneous requirements. Carriers such as Fedex/DHL/CanadaPost also have lockdown issues and delays.

We are doing the best we can under the circumstances and we thank you for your patience. This may take a little longer than usual.     — Support Team
