I've been a Virtual Post Mail (https://www.virtualpostmail.com/) customer for 10 years so far and they've been great. Reliable and very quick to respond to support emails on the rare occasion it was needed.

I have been using ClevverMail for personal stuff since about 3 years ago and I am happy with it. I do not receive a lot of mail on that address (incidentally in Toronto as well) so it usually costs about $5/month. They have a lot of locations and mine is a UPS Store that handles the scanning/mailing etc.

For UK specifically I've been using ScanMyPost which comes out to even less per year and is run by the same people that keep track of your credit score (and potential fraud) and I'd trust them even more.

I've been using MailboxForwarding.com for several years. $15 per month gets you 50 items received and 15 scanned. They also offer additional services like parcel storage/forwarding and check depositing. Been solid since I have been using them.

Definitely be careful about choosing such a place and the services they offer. When I was running a solo startup I used a mail handler that promised email notifications of all arriving mail. But those notifications never came, I got busy with other things, and an important document sat in a mailbox for months. I should have been more diligent about following up, but the net result was that a possible large deal became a guaranteed nothing, due to my reliance on a service that failed me.

Yup. And as a bonus, they'll throw out all the junk mail. Also, if you travel a lot, or often relocate overseas, for a very reasonable rate they'll bulk mail you everything on whatever frequency you would like.
