To your attention please.
Be aware in case of medical emergency of your clients to whom you helped in anything in any way you may be financialy responcible. You should advise them to buy Visitors to Canada medical emergency insurance. It is available online.
I have three different companies for your choice. If you need I can embed the link(s) on your websites with all necesarry explanations.
In case your clients refuse to buy medical insurance you have to get it in writing from them with their signature.
Good luck!
A lawyer or consultant who did not advise a client to buy medical insurance is NOT liable financially for costs that may be incurred unless they told the applicant that medical insurance was NOT necessary. But the onus is not on the representative to advise the client that they need this. The client is accountable for their own decisions or lack thereof in this regard.
