Most of the organizations that financial advisors belong to have a function to find their members. The major ones are listed below:
Advocis seems to be the largest organization, with CFPs (Certified Financial Planners) and some Insurance designations. The Advocis advisor search feature can be found here.
FPSC is another organization that has a search for CFPs. Many of the same CFPs are in the Advocis database, but some aren't. The FPSC advisor search feature can be found here.
IAFP is an organization of Registered Financial Planners (RFP). The database is smaller but the designation comes with prestige and is meant to be a mark of quality. The IAFP advisor search feature can be found here.
Finally, there is a site — full disclosure, I am affiliated with it — called wealthprep.ca that has a large listing of advisors in Canada. You can filter by profession, specialties, and compensation type and there are ratings and reviews. Here is the page specifically for Toronto Financial Advisors.
