That’ll be quite easy as you have your daughter to prove reason for travel and even accommodation if required.
@dianae, welcome to Canada 
. Please don’t call Canadian pet parents “clients”, as this encourages polite folks to take employer mindset

Not sure of your origin country. Or broader travel plans. We find that traditional travel insurance is pointless for extended housesitting - as most related coverage relates to start/end travel rather than any coverage during visit. That said, we always have emergency medical insurance. We use two different services, depending on continent of destination. In case useful, we find that Genki offers a usefully flexible duration emergency medical insurance policy - pay by-the-month (stop when want) with broad coverage options World-ExUS or World-IncUS.
Hope enjoy your adventures.
She will be traveling around and working on animal sanctuaries so I couldn’t stay with her but I’ve also got a step brother that lives in Vancouver so could use his address.
Thanks for your help.
I recently got a new credit card that actually provides travel insurance. I wonder if that would be considered sufficient.
I was dubious the first time travelling with just the credit card insurance, but when I looked into it, it was a standard travel policy with a reputable company. Have used it many times but never had to claim so I can’t report on that. No reason why it wouldn’t cover you for a country that requires it.
It is necessary to prove that you have medical/health insurance.
This is so the taxpayers of the country you are entering do not have to bear the full burden of any medical expenses while you are in country.
If you are asked about travel insurance, that might be another way for customs and border authorities to determine the veracity of your statements as such insurance when purchased is usually only purchased for the duration of your trip…further evidence of whether you are actually intending to leave.
Citizens of some countries require VISAs to enter Canada. Those can require onerous disclosure of financial resources (at home and for the visit) and related proof of intention to leave.
Americans and others who do not have universal healthcare are familiar with having to purchase health/medical insurance. If you are from a country with universal or subsidized health/medical insurance it can seem like a huge expense to have to purchase it just for a trip.
