Given that Canada allows transit and has flight to Europe and Mexico, you can do Europe-Canada-Mexico-14 days-USA, assuming no additional restriction is imposed in coming days (not a safe assumption, so only do this is absolutely urgent and necessary).
The Canadian Embassy in Switzerland suggested to Canadian citizens in Switzerland there are still flights operating from London Heathrow or Frankfurt by Air Canada.
UK has no current restrictions for European passengers transiting. But Germany may deny entry (at land borders, at least). Transiting to home countries is allowed by Germany but I'm not sure if this kind of itinerary will be accepted by the border.
The flights to Toronto (YYZ) offer the possibility of airside transfer if the terminal is the same and baggage is checked through. You can check if a pair of flights is compatible at https://www.torontopearson.com/en/connections. Overnight connections may require you to pick up your baggage.
The Orders exempt foreign nationals in transit through Canada to another country. Given the interplay between the interim order under the Aeronautics Act and related emergency orders under the Quarantine Act, the airport of arrival into Canada must have the facilities to permit the foreign national to connect to their destination without the foreign national having to present themselves for examination to enter Canada.
Canada has a mandatory mask requirement for air passengers. You will be refused boarding without appropriate face coverings.
If you are planning to return to Canada, please note the new Transport
Since 20 April, Transport Canada will require air operators to verify
that all travellers have a removable cloth face covering available for
use during their trip, even if the travellers are not showing any
symptoms. When travelling by air, you will be asked to cover your
mouth and nose where possible, and must do so when a two-metre
distance between you and others cannot be observed. At a minimum,
- at airport screening checkpoints, where the screeners cannot always keep two metres of separation from you;
- when you cannot physically distance from others, or as directed by the airline employees; and
- when directed to do so by a public health order or Public Health official.
If you do not have one available for your trip, the air operator will
be required to deny you entry into the sterile area, or boarding on
It is your responsibility to bring the required cloth face covering to
the airport. You will not be provided with one if you do not have one.
Consular officials from the government of Canada will not be in a
position to provide masks either.
How to make simple cloth face coverings
There are many online resources available with information on how to
make simple cloth face coverings. The Public Health Agency of Canada’s
(https://www.canada.ca/en/public-health/services/diseases/2019-novel-coronavirus-infection/prevention-risks/instructions-sew-no-sew-cloth-face-covering.html) provides suggestions for simple “do it yourself” cloth
covers that can be easily made from inexpensive materials found at
home, or even while travelling. In general, though:
choose fabric that can be laundered without damage;
- include multiple layers of fabric;
- allow for breathing without restriction; and
- think about having more than one for each traveller, so it can be replaced if damp or soiled.
Cloth coverings should fit snugly but comfortably against the side of
your face, be secured with ties or ear loops and cover your face and
nose. It should be easy to put on and take off when necessary (e.g.,
identity verification check).
Cloth face coverings should not be worn by:
- children under the age of two;
- anyone who has trouble breathing; or
- anyone who is unconscious, incapacitated or otherwise unable to remove the mask without assistance.
Also note that you may be asked to remove your face covering for the
purpose of identity verification at the boarding gate and the
customs-controlled area when you arrive at the Canadian airport or
when asked to do so by Canada Border Services Agency officers or
public health officials.
You are encouraged to use hand sanitizer before removing and after
replacing your face covering.

Frankfurt (Hessen) requires face-nose covering.
Please note that since April 27, 2020, masks have been required all over Hessen in local public transport vehicles and in the public areas of shops, banks and post offices. This regulation also applies to the bus shuttle and SkyLine, as well as shops at Frankfurt Airport.
